Frequently Asked Questions
Understand Our Tests
What biomarkers does this panel measure?
This panel measures Testosterone (Free and Bioavailable), Thyroid-Stimulating Hormone (TSH), Sex Hormone-Binding Globulin (SHBG), Vitamin D, and Prostate-Specific Antigen (PSA). Together, these biomarkers provide insight into hormone balance, metabolism, prostate health, and overall wellbeing.
Why is testosterone important for men’s health?
Testosterone is the primary male sex hormone produced in the testis. It plays an important role in reproductive health, muscle mass, bone density, and overall health. Low testosterone may cause low libido, fatigue, loss of muscle, and mood changes, while high testosterone may be associated with irritability, aggression, enlarged prostate, or acne.
What does Thyroid-Stimulating Hormone (TSH) indicate?
TSH is produced by the pituitary gland and regulates the function of the thyroid gland, which controls metabolism, energy levels, and overall hormonal balance. High TSH levels usually indicate hypothyroidism, while low TSH levels can suggest hyperthyroidism.
What role do SHBG and Vitamin D play in this panel?
SHBG is a protein produced mainly in the liver that binds to sex hormones such as testosterone and estrogen, helping regulate how much active hormone is available in the body. Vitamin D supports bone health, immunity, hormone balance, and energy levels. Low vitamin D levels have also been linked to lower testosterone and reduced sperm quality.
When is the best time to take this test?
Testosterone levels decline throughout the day, so it is best to take this test first thing in the morning to obtain the most accurate results.
