How to Actually Get Tested for Low Testosterone

Why It Matters

Accurate testosterone testing prevents unnecessary TRT prescriptions, safeguarding patient health and reducing liability for clinics.

Key Takeaways

  • Testosterone labs must be drawn 7‑10 a.m., fasting, healthy.
  • Repeat testing confirms low results; half normalize without treatment.
  • Include LH, FSH, SHBG to locate source of deficiency.
  • Free testosterone ordered only when SHBG abnormal or clinical mismatch.
  • Many clinics prescribe TRT from single afternoon draw, bypassing proper evaluation.

Summary

The video explains how clinicians should correctly order and interpret testosterone testing to avoid misdiagnosis.

It stresses that blood draws must occur between 7:00 and 10:00 a.m., after an overnight fast, and when the patient is not acutely ill or sleep‑deprived. A single low total testosterone reading is insufficient; a repeat morning draw under identical conditions is recommended. Ancillary hormones—LH, FSH, SHBG—and sometimes prolactin are added to differentiate primary testicular failure from secondary hypogonadism and to detect binding‑protein anomalies.

The presenter illustrates a “worst‑case” scenario where a patient arrives after a sleepless night, alcohol, and a meal, artificially suppressing testosterone and prompting an unnecessary TRT prescription. He also cites industry data: fewer than 25 % of men receive a baseline testosterone test before starting therapy, and half of those on TRT never have a follow‑up level checked.

These practices expose patients to unwarranted hormone therapy, increase legal risk, and undermine clinic credibility. Implementing the outlined protocol can improve diagnostic accuracy, ensure appropriate treatment, and align business models with evidence‑based care.

Original Description

Less than a quarter of testosterone prescriptions in the US are written after the patient gets a single lab. Half of patients who start TRT never get a follow-up level checked. The wellness-clinic playbook is engineered to skip the workup, because the workup is what would catch the cases where TRT isn't actually the answer.
Dr. Jordan Feigenbaum and Dr. Austin Baraki walk through how a real testosterone workup gets done: morning sample, fasted, not during illness or after a run of bad sleep; total testosterone first, then on the repeat draw, add LH, FSH, and SHBG to localize the problem and check the binding protein.
