A Lyme disease blood test looks for antibodies to Borrelia bacteria, not the tick-borne bacteria itself. Learn how two-tier testing works, when results are reliable, what IgM and IgG mean, and what to ask your clinician after a positive, negative, or equivocal result.
Compare self-pay Lyme disease blood test prices, mandatory fees, collection options, and what to check before buying a direct-to-consumer Lyme antibody test.
CMV blood test results can be confusing because “high” or “low” may refer to IgG antibodies, IgM antibodies, IgG avidity, or CMV DNA viral load. Learn what common CMV result patterns usually mean, when follow-up testing is needed, and what to discuss with a clinician.
A CMV blood test checks for evidence of cytomegalovirus infection, usually with IgG and IgM antibodies or, in higher-risk patients, CMV DNA by PCR. Learn what the test measures, how to prepare, how results are interpreted, and when follow-up testing may be needed.
Self-pay CMV blood test prices vary widely depending on whether you need CMV IgG, CMV IgM, both antibodies, or CMV PCR. This guide compares effective consumer costs, mandatory fees, availability, and when each test type makes sense.
High or low EBV results depend on which marker is abnormal. Learn how VCA IgM, VCA IgG, EBNA IgG, Early Antigen, and EBV PCR are interpreted.
An EBV blood test checks for antibodies to Epstein-Barr virus, a common cause of mono. Learn what VCA IgM, VCA IgG, EBNA, Early Antigen, and Monospot results can and cannot tell you.
Self-pay EBV blood test costs vary widely depending on whether you buy a 3-marker antibody panel, add early antigen, choose PCR testing, or use a local hospital direct-access lab. Compare effective cash prices, fees, what each test includes, and how to choose the right option.
An HSV blood test looks for herpes antibodies, not the virus itself. Learn when HSV IgG testing is useful, how to prepare, how to interpret HSV-1 and HSV-2 results, and when confirmation is needed.
Hepatitis C results are usually interpreted as reactive/nonreactive and RNA detected/not detected—not simply high or low. Learn what each result means and what to do next.
