Conditions FAQs
Can a blood test diagnose a condition by itself?
Sometimes a laboratory result can meet a diagnostic criterion, but many diagnoses require symptoms, repeat testing, imaging, examination, or other clinical information.
Why are the same tests listed under multiple conditions?
Many laboratory markers are not disease-specific. A CBC, CMP, glucose, or TSH can be useful in several different evaluations.
Should I order every test associated with a condition?
No. More testing is not always better. The useful set of tests depends on the question, symptoms, history, and prior results.
Where should I start if I do not know which test I need?
Start with the Lab Tests and Conditions hubs for education, or discuss individualized testing with a qualified healthcare professional.
