A prolactin blood test is used by doctors to evaluate sexual dysfunction or very low testosterone blood levels of unknown causes in both men and women.

This panel includes comprehensive testing of the thyroid stimulating hormone (TSH) in addition to free thyroxine (T4) and free triiodothyronine (T3).

THIS IS THE MOST AFFORDABLE TESTOSTERONE TEST IN THE U.S. The most accurate way to measure total testosterone is with liquid chromatography/mass spectrometry. This panel also shows free testosterone percent by equilibrium dialysis and free testosterone calculated from percent free T. This test is more accurate for low and high testosterone blood levels (for men who expect high testosterone blood levels over 1,500 ng/dL, women, and children who usually have low T levels). It has no interferences with supplements or anabolics. Note: Results may take 5-7 business days. For a faster turnaround, choose this test instead: Testosterone, Free, Bioavailable and Total (With Lower & Upper Limit) plus SHBG

The PTH test is used to help identify hyperparathyroidism, to find the cause of abnormal calcium levels, or to check the status of chronic kidney disease. PTH controls calcium and phosphorus levels in the blood.
