How to prepare for Cortisol Kinder

Preparing for a cortisol test (e.g., MyBody-X Cortisol Kinder) depends on the test type. For saliva tests, timing is critical: cortisol follows a circadian rhythm – samples are usually taken in the morning (30 min after waking) and in the evening. Avoid eating, drinking (except water), brushing teeth, and intense exercise for 1 hour before. For blood or dried blood spot tests, similar rules apply. A single measurement is not diagnostic; it only provides a snapshot. In children, interpretation is especially challenging because reference ranges vary by age. Evidence is based on lab practice, not large clinical trials. If results are abnormal, always consult a pediatrician. Do not overinterpret – cortisol fluctuations are normal. The test can be a useful trend indicator but not a standalone diagnosis.
