Question 47 of 433
Which ordinary blood tests matter most?

The short answer
Start with tests that answer a clinical question. There is no universal longevity panel that every healthy adult needs yearly.
Lipids help guide cardiovascular prevention. Measure Lp(a) at least once in adulthood; use ApoB selectively when it clarifies particle-related risk. HbA1c, fasting glucose, or an oral glucose tolerance test are established ways to assess abnormal glucose regulation when screening is appropriate.
Kidney testing, including urine albumin in people with diabetes or other relevant risks, can change care. Blood counts, liver tests, TSH, ferritin, B12, and vitamin D are chosen according to symptoms, conditions, medications, and risk. A useful test for fatigue is not automatically a useful screen for everyone.
Routine fasting insulin or HOMA-IR testing is not recommended for most people by the ADA/AACC laboratory guideline. hs-CRP may help selected cardiovascular risk discussions; it is nonspecific and does not belong on every annual panel. Ask what decision a result will change.
