Name of the Procedure:

Testosterone; free

Summary

A free testosterone test measures the amount of testosterone not bound to proteins in your blood. Testosterone is a crucial hormone in both men and women, affecting muscle mass, mood, bone density, and sexual function.

Purpose

The free testosterone test helps diagnose conditions related to abnormal testosterone levels. It assists in identifying issues such as hormonal imbalances, infertility, erectile dysfunction, and diseases affecting the pituitary gland.

Indications

• Unexplained fatigue or depression
• Decreased libido or sexual dysfunction
• Unexplained weight gain or muscle loss
• Irregular menstrual cycles or menopausal symptoms
• Evaluation of fertility issues

Preparation

• Fasting may not be required; follow physician’s instructions.
• Avoid strenuous exercise for at least 24 hours before the test.
• Inform the healthcare provider about any medications or supplements you are taking.

Procedure Description

1. Blood Sample Collection: A healthcare provider will use a needle to draw blood from a vein, usually in your arm.
2. Sample Processing: The blood sample is sent to a laboratory where it's analyzed to measure the levels of unbound testosterone.
3. Analysis and Reporting: Results are reviewed by a medical professional to interpret the free testosterone levels in context with the patient's specific symptoms and health history.
