Short answer: Open the Dashboard button, then Tools, then Lab Targets. Each marker has a card. Enter a Low, a High or both, and tap Save. Your target then decides what counts as on target for that marker. With no target set, the app uses the range printed on your lab report.
Before you start: Targets are yours to set, usually with your clinician. The app does not suggest one.
The list includes Total Testosterone, Free Testosterone, Estradiol, TSH, HDL, LDL, Fasting Glucose, HbA1c, Ferritin and Vitamin D (25-OH). Each card says whether higher is better, lower is better, or the value should sit within a range. The grey numbers in empty fields are placeholders, not advice.
Lab ranges differ between labs, and a personal target is a choice you make with your clinician. See the glossary for what each test measures, for example hematocrit.
