PCOS Diagnostic Profile
Use
This panel is intended to aid physicians in diagnosing polycystic ovary syndrome (PCOS) by assessing biochemical hyperandrogenism and ruling out other disorders that mimic the clinical features of PCOS. This assay provides the sensitivity and specificity required for the assessment of the low testosterone levels found in women, children, adolescents, and hypogonadal men.1
Special Instructions
Not provided.
Limitations
This test was developed and its performance characteristics determined by Labcorp. It has not been cleared or approved by the Food and Drug Administration. Guidelines also recommend excluding thyroid disease (TSH), prolactin excess, and nonclassical congenital adrenal hyperplasia before diagnosing PCOS. Additionally, women should potentially be evaluated to rule out pregnancy, hypothalamic amenorrhea, primary ovarian insufficiency, androgen-secreting tumor, Cushing's syndrome, and acromegaly depending on clinical presentation.
