A balanced iron status appears favorable. However, evidence that self-testing ferritin directly extends lifespan is weak: no randomized trials show that home monitoring improves longevity outcomes. Self-test accuracy is acceptable but inferior to venous lab testing. Moreover, lay interpretation is error-prone – a low-normal ferritin can be masked by inflammation.
