Lab ranges

Dihydrotestosterone (DHT) — lab reference

Method-specific. Clarify its role in hair, prostate, androgen therapy, or enzyme questions.

Free PSA / total PSA — lab reference

Often used when total PSA is in an indeterminate zone. Ask your clinician to use the performing-lab risk table.

hCG, quantitative — lab reference

Ask your clinician to use exact assay cutoff and clinical indication.

Inhibin B — lab reference

May assist selected fertility evaluations; not a routine wellness marker.

PSA, total — lab reference

No single normal cutoff fits every patient. Ask your clinician to use age, baseline, trend, prostate size, risk factors, and shared decision-making.
