Order Total Testosterone Testing | Low T TestTotal testosterone testing measures the amount of testosterone circulating in the bloodstream. Testosterone is a hormone produced primarily in the testes in men and in the ovaries and adrenal glands in women, with smaller amounts produced elsewhere in the body. Because testosterone influences muscle mass, bone density, red blood cell production, mood, and sexual function, a total testosterone test is often used to evaluate symptoms that may point to levels that are too high or too low.
About Total Testosterone Testing | Low T Test in Castro Valley
Total testosterone testing is a straightforward blood test that quantifies the overall concentration of testosterone in the blood.
The test measures total testosterone, which includes testosterone bound to proteins such as sex hormone-binding globulin (SHBG) and albumin, as well as the small fraction that circulates unbound. This total value is the most commonly ordered initial assessment when a clinician suspects an androgen imbalance.
Results are typically reported in nanograms per deciliter (ng/dL) or nanomoles per liter (nmol/L), and reference ranges vary by laboratory, age, and sex. Because testosterone levels fluctuate throughout the day and can be affected by sleep, stress, illness, and certain medications, a single result is usually interpreted alongside symptoms and, when appropriate, repeat testing.
Total testosterone testing is used in both men and women. In men, it may be ordered to investigate low libido, fatigue, erectile dysfunction, or infertility. In women, it may be ordered when there are signs of excess androgen, such as acne, unusual hair growth, or menstrual irregularities. In children, it may be used to evaluate early or delayed puberty.
