Understanding Hormonal Tests: What You Need to Know
Why Hormonal Testing Matters
Hormonal tests, such as testosterone, prolactin, and SHBG (sex hormone-binding globulin), are critical for understanding overall health. They can reveal imbalances that affect energy levels, mood, fertility, and more.
Key Hormonal Tests
- Testosterone: Essential for male reproductive health, muscle mass, and energy. Testing both total and free testosterone provides a full picture.
- Prolactin: High levels may indicate stress or pituitary issues, affecting libido and hormonal balance.
- SHBG: Regulates the availability of testosterone. High levels can mask low free testosterone, leading to undiagnosed symptoms.
Preparing for Hormonal Tests
Proper preparation ensures accurate results:
- Avoid heavy meals and alcohol for 24 hours before testing.
- Maintain your usual diet; drastic changes can skew results.
- Schedule tests for late morning to avoid naturally elevated hormone levels early in the day.
- Continue medications or supplements only if instructed by your doctor.
Choosing the Right Lab
Not all labs are the same. Opt for facilities with advanced equipment like mass spectrometers, which provide more precise results compared to basic immunoassay analyzers.
Stick to one lab for consistent monitoring over time, as methods and reference ranges vary between facilities.
Interpreting Results
Always consult a qualified doctor to interpret test results. Relying solely on reference ranges or highlighted values can lead to misdiagnoses. Hormonal levels must be assessed in the context of your symptoms and overall health.
