How often should you actually retest?

The honest answer is less often than most testing companies would like. Markers move at different speeds, and retesting faster than a marker can change tells you nothing except how much noise your assay has.

A workable rhythm

A full panel once a year is enough for most healthy adults. After starting a supplement, a medication or a serious training block, retest the specific markers at twelve weeks — long enough to move, short enough to act.

The exceptions

Ferritin after iron therapy, HbA1c after a metabolic change, and thyroid after a borderline result all deserve their own timeline. Lp(a) you measure once and never again.

Your report always names the markers worth rechecking and when — so you are not guessing between appointments.
