Quick take
- Typical self-pay range: many online U.S. options for Factor V Leiden mutation testing fall around $185–$389 total after obvious mandatory fees, although some providers list much higher prices.
- Lowest visible total is not always the best fit: compare the final checkout total, lab network, state restrictions, result turnaround, cancellation policy, and whether clinician review or genetic counseling access matters to you.
- This is usually a one-time DNA test: a clinical Factor V Leiden test looks for a specific inherited variant in the F5 gene. Your DNA result does not change over time.
- A positive result is a risk marker, not a diagnosis of a current clot: Factor V Leiden increases the tendency toward venous blood clots, but many people with the variant never develop one.
- Testing is most useful when it will change a decision: examples include a personal history of venous thromboembolism, certain family histories, pregnancy or estrogen-related decisions, and unusual-site clots—ideally discussed with a clinician.

Factor V Leiden test cost: self-pay options compared
If you are searching for factor v leiden test cost, the most practical number is the effective cost to the patient: the test price plus any mandatory physician, requisition, service, or specimen-collection fee that appears before you can complete the order. For Factor V Leiden, advertised prices can look similar but final totals differ because one site may include the lab draw while another adds it at checkout.
The table below compares commonly visible national self-pay options for a standalone Factor V Leiden mutation analysis. Prices can change, coupons may apply, and some sites block orders based on residence or collection state, so treat the table as a consumer checklist rather than a medical recommendation.
| Provider / ordering route | Listed Factor V Leiden price | Mandatory fee visible from provider information | Estimated effective total | Lab / collection notes | Consumer considerations |
|---|---|---|---|---|---|
| Push Health | $175.27 listed as all-inclusive | Not separately shown in public search result | About $175.27 if checkout confirms no added fee | Provider-assisted online ordering; verify lab network and state availability before purchase | Potentially low listed total, but confirm details at checkout because the full page may not show the same way for every location |
| Marek Diagnostics | $175.00 | $10 venipuncture fee for individually built biomarker orders | About $185.00 | Quest collection; provider review before approval; results typically within about two weeks | Public page states no extra payment is due at the lab, but orders are not processed for residents of NY, NJ, or RI |
| Ulta Lab Tests | $185.95 | $12.95 standard draw fee unless a chosen collection site shows a different amount | About $198.90 | Quest collection; no special preparation listed for the test | Usually one of the lower clear totals; verify draw fee and collection-site availability during checkout |
| Request A Test — Labcorp option | $249.00 | $4.00 per-order service fee | About $253.00 | Labcorp test code 511154; blood specimen | Useful when Labcorp access is better locally; public page lists a longer Labcorp turnaround estimate than the Quest option |
| Walk-In Lab | $249.00 | $6.00 per-order physician fee | About $255.00 | Labcorp or Quest test codes shown; blood specimen; no special prep | Clear fee disclosure; public page lists 5–8 days and states orders are restricted in NY, NJ, and RI |
| Request A Test — Quest option | $279.00 | $4.00 per-order service fee | About $283.00 | Quest test code 17900; blood specimen | May be worth comparing if Quest is more convenient than Labcorp in your area |
| LabsMD | $364.00 shown in test list | Separate required fees not clearly visible in search result | At least $364.00 if no additional checkout fee applies | Quest-style online lab ordering; confirm test name and final total | Higher than several clear all-in alternatives for the same type of standalone test |
| True Health Labs | $389.00 | Provider page states pricing includes collection fees at patient service centers | About $389.00 | Quest test; availability allowed only when address and testing are outside NY, NJ, MA, and RI | More expensive than several competitors, but collection-fee inclusion is clearly described |
| Private MD Labs | $1,045.00 | Page states prescription and lab fees included | About $1,045.00 | Quest and Labcorp locations shown; doctor notes included | Substantially higher listed price; consider whether included result explanation justifies the difference for your situation |

How we compared prices
For this article, providers were compared by the consumer’s expected out-of-pocket total, not by commission or promotional placement. The effective total includes the listed test price plus mandatory order, physician, service, requisition, or draw fees when those fees were visible. Optional coupons, subscription discounts, financing, and first-time-user promotions were not treated as base price because they may not be available to every reader. When a provider did not clearly show a required fee, the table describes that uncertainty rather than assuming the provider is cheaper.
What the Factor V Leiden test checks
Factor V Leiden is a specific inherited variant in the F5 gene. The variant changes factor V, a protein involved in blood clotting, so that the clotting process can remain active longer than usual. This increases the tendency to form abnormal venous clots, especially deep vein thrombosis (DVT) and pulmonary embolism (PE). MedlinePlus Genetics explains that people with one copy of the variant have a higher annual clot risk than the general population, while people with two copies have a higher risk than those with one copy.
Most standalone clinical tests are targeted DNA tests. They do not sequence the whole F5 gene, and they do not test every possible inherited or acquired clotting condition. Labcorp’s Factor V Leiden Mutation Analysis, for example, lists allele-specific PCR methodology, test number 511154, CPT code 81241, and a usual turnaround of 5–7 days from specimen pickup to result release. Its specimen requirements include whole blood or a Labcorp buccal swab kit, although many self-pay storefronts use a blood draw workflow. See Labcorp’s test menu for methodology, specimen, and limitation details.
A Factor V Leiden mutation test is different from a Factor V activity test. Factor V activity is a clotting-protein function test that may be used in bleeding or coagulation evaluations. Factor V Leiden mutation analysis is a genetic thrombophilia test focused on a clotting-risk variant. If you are ordering on your own, make sure the name says Factor V Leiden mutation, F5 Leiden, or Factor V R506Q / Arg534Gln, not simply “Factor V activity.”
Who may benefit from Factor V Leiden testing?
Testing is most useful when the result would change medical counseling, prevention, or treatment decisions. The American Society of Hematology 2023 thrombophilia testing guideline supports selective testing in certain scenarios, such as VTE associated with nonsurgical major transient or hormonal risk factors, some unusual-site clots, and specific high-risk family-history situations. The guideline also recommends against broad general-population testing before starting combined oral contraceptives.
Common reasons a clinician may consider Factor V Leiden testing include:
- a personal history of DVT or PE, especially if it occurred at a young age, was recurrent, was unprovoked, or happened with pregnancy or estrogen exposure;
- a first-degree relative with Factor V Leiden, recurrent VTE, or a known high-risk thrombophilia;
- planning pregnancy or postpartum prevention when family history suggests high-risk thrombophilia;
- venous clots in less common locations, such as cerebral or splanchnic veins, when the result could affect anticoagulation duration;
- decision-making about estrogen-containing birth control or hormone therapy in someone with a strong personal or family clotting history.
The ACMG technical standard for Factor V Leiden and prothrombin thrombophilia testing emphasizes testing when results will influence treatment or clinical management, or when counseling certain relatives could reduce provoked VTE risk during higher-risk circumstances.
How self-pay Factor V Leiden ordering works
Most self-pay services follow a similar path. You choose the test online, enter demographic information, pay by card or HSA/FSA if accepted, and receive a lab order authorized through the service’s physician network or ordering provider. You then visit a participating Quest or Labcorp patient service center for the blood draw. Results are usually posted to the provider portal and may also be available through the reference lab’s patient portal.
Before paying, check five details:
- Final total: confirm the test price plus draw, physician, service, or requisition fees.
- Correct test: choose Factor V Leiden mutation analysis, not Factor V activity.
- Lab network: pick Quest or Labcorp based on local access, appointment availability, and whether your state allows the order.
- State restrictions: many direct-access lab services restrict NY, NJ, RI, and sometimes MA. Restrictions can depend on your address, collection location, and the provider’s legal workflow.
- Result support: decide whether you only need the lab report or want clinician notes, a telehealth visit, or genetic counseling.
No special preparation is usually required. Walk-In Lab lists no special preparation for its Factor V Leiden mutation analysis, and Ulta’s test listing states no preparation instructions. For a DNA-based Factor V Leiden test, fasting is not the issue; the bigger issue is making sure the specimen is collected and labeled correctly and that your clinician understands your clinical context.
Blood draw vs cheek swab vs consumer DNA reports
Clinical Factor V Leiden testing can be performed from blood and, in some laboratory workflows, from a buccal swab. Labcorp’s test menu lists whole blood or a Labcorp buccal swab kit as acceptable specimen types for its test. Self-pay storefronts, however, usually send consumers to Quest or Labcorp for a blood draw because that is the easiest standardized workflow.
Direct-to-consumer genetic services are a separate category. The FDA’s direct-to-consumer testing information states that the 23andMe hereditary thrombophilia report is indicated for reporting the Factor V Leiden variant in F5 and the prothrombin G20210A variant in F2, but it also notes that such a report does not describe a person’s overall risk of developing harmful blood clots. See the FDA’s direct-to-consumer test information. If a consumer DNA report shows Factor V Leiden and you are making medical decisions about anticoagulation, pregnancy, surgery, or hormones, bring the report to a clinician; many clinicians will confirm with a clinical laboratory test.
How to read Factor V Leiden results
Results are usually reported as one of the following:
| Result wording | Plain-language meaning | Practical next step |
|---|---|---|
| Negative / not detected / no mutation detected | The tested Factor V Leiden variant was not found. | This reduces concern for this specific inherited risk factor, but it does not rule out other inherited or acquired causes of clotting. |
| Heterozygous / one copy detected | One copy of the Factor V Leiden variant was found. | Discuss clot history, family history, estrogen exposure, pregnancy, surgery, travel, smoking, and other risks with a clinician. Many people with one copy never have a clot. |
| Homozygous / two copies detected | Two copies of the variant were found. | Clinical follow-up is important because clot risk is higher than with one copy, especially around pregnancy, surgery, immobility, and other risk factors. |
MedlinePlus gives a helpful scale: about 1 in 1,000 people per year in the general population develop an abnormal clot; one copy of Factor V Leiden increases that to about 3 to 8 in 1,000, while two copies may raise it much higher. These are population estimates, not a personal prediction. Your actual risk also depends on age, prior clot history, body weight, smoking, pregnancy, surgery, immobility, cancer, estrogen-containing medications, and other thrombophilias.
A positive Factor V Leiden result does not automatically mean you need lifelong anticoagulant medication. GeneReviews notes that heterozygosity alone is not an indication for long-term anticoagulation in the absence of other risk factors. Treatment decisions depend on whether you have had a clot, what triggered it, bleeding risk, and whether future high-risk periods are expected.
Limitations, risks, and what this test cannot tell you
Factor V Leiden testing is analytically strong when performed by a qualified clinical lab, but no lab test is perfect. Labcorp’s test menu states that molecular testing is highly accurate but diagnostic errors may occur and that results must be combined with clinical information. It also lists potential causes of false results or interpretation problems, including rare genetic variants, blood transfusion, bone marrow transplantation, tissue-specific mosaicism, mislabeled samples, and erroneous family-relationship assumptions.
The test also has scope limits. A standalone Factor V Leiden mutation analysis generally does not check prothrombin G20210A, antithrombin deficiency, protein C deficiency, protein S deficiency, antiphospholipid syndrome, elevated factor VIII, malignancy-related clotting risk, or non-genetic clot triggers. If you have had a DVT, PE, recurrent pregnancy loss, or an unusual clot, do not assume a negative Factor V Leiden test closes the evaluation. A clinician may recommend a broader thrombophilia panel, timing-sensitive functional assays, imaging follow-up, or medication review.
Cost is another limitation. A $185 self-pay test may be cheaper than using insurance with a high deductible, but insurance may cover testing when ordered for a documented medical indication. On the other hand, ordering outside insurance can mean the result is not automatically integrated into your medical record. If the result may affect surgery, pregnancy, contraception, hormone therapy, or anticoagulation, share it with the clinician who manages those decisions.
Customer-satisfaction patterns to consider
Public reviews are imperfect, but they can reveal practical issues such as whether lab orders arrive, whether results post promptly, and whether support responds when a specimen or appointment problem occurs. Ulta Lab Tests shows a Trustpilot profile around 4.5 out of 5 with reviewers commonly praising price and convenience, while complaints mention delays, website issues, or mismatched expectations about turnaround. Jason Health has a smaller Trustpilot review base with a similar high score and comments emphasizing low prices and ease of use. Walk-In Lab publishes a review page citing a high average rating from third-party review sources and large customer volume. Private MD Labs displays a large Google review count on its test page and emphasizes included doctor notes, but its Factor V Leiden price is far higher than many alternatives. Review scores should not override clinical fit or total cost, but they are worth checking before purchase.
Review sources used for general satisfaction patterns include Ulta Lab Tests on Trustpilot, Jason Health on Trustpilot, and Walk-In Lab’s review page.
Practical next steps before you buy
- Write down why you want the test. Family history, prior clot, pregnancy planning, or hormone decisions each have different implications.
- Ask whether the result will change care. If the answer is no, testing may provide information but not necessarily action.
- Compare the same test code when possible. Labcorp 511154 and Quest 17900 are common standalone Factor V Leiden mutation analysis codes in self-pay listings.
- Save the report. Genetic test results may matter years later for surgery, pregnancy, family testing, or medication decisions.
- Follow up promptly for positive results. A primary care clinician, hematologist, OB-GYN, or genetic counselor can help interpret the result in context.
Seek urgent care immediately for symptoms that could suggest a blood clot, such as one-sided leg swelling or pain, sudden shortness of breath, chest pain, coughing blood, fainting, or rapid unexplained heartbeat. A genetic test is not used to rule out an active DVT or PE; suspected clots require timely medical evaluation and imaging or other acute testing.
FAQs
How much does a Factor V Leiden test cost without insurance?
Common self-pay totals are roughly $185–$389 when visible mandatory fees are included. Lower or higher prices exist, so compare the final checkout total rather than the advertised test price alone.
Is Factor V Leiden testing covered by insurance?
It may be covered when ordered for a documented medical reason, such as certain clot histories or family-history scenarios. Coverage varies by plan and indication. If you have a high deductible, the cash price may still be lower than your insurance-applied cost.
Do I need a doctor’s order?
Clinical labs generally require an order. Self-pay lab websites usually supply that order through their own licensed provider network after you purchase the test. That is different from receiving individualized medical advice from your own clinician.
Is this test done only once?
Usually yes. Factor V Leiden is inherited, so a valid clinical DNA result generally does not change. Repeat testing is mainly considered when a previous result was from a nonclinical consumer source, the original report is unavailable, or there is concern about specimen or reporting accuracy.
Can I test during pregnancy or while taking blood thinners?
A DNA-based Factor V Leiden mutation test is less affected by pregnancy or anticoagulant medication than many functional clotting assays. Still, tell your clinician and the ordering service about pregnancy, anticoagulants, recent transfusion, or transplant history because those details may affect broader thrombophilia evaluation and interpretation.
What is the difference between Factor V Leiden and prothrombin mutation testing?
Factor V Leiden testing looks for a variant in the F5 gene. Prothrombin G20210A testing looks for a variant in the F2 gene. Both are inherited thrombophilia tests, but they are different variants and may be ordered together when a clinician wants a broader inherited clot-risk assessment.
Should my family members be tested if I am positive?
Possibly, but not automatically. Testing relatives is most helpful when the result would change decisions about pregnancy, estrogen-containing medications, surgery, travel precautions, or clot prevention. A clinician or genetic counselor can help decide which relatives, if any, should be tested.
Can a negative result rule out blood clot risk?
No. A negative Factor V Leiden result only means the tested variant was not detected. Blood clots can still occur from surgery, immobility, cancer, pregnancy, estrogen exposure, antiphospholipid syndrome, other inherited thrombophilias, or no obvious trigger.
