Estradiol "sensitive" assay
Is the Estradiol "sensitive" assay more accurate than the standard test?
Are the standard test results not useful?
Both the Labcorp standard E2 test (004515 CPT Code: 82670) and the E2 "sensitive" test (140244 CPT Code: 82670) measure pg/mL and have ranges for adult Men:
Sensitive 3-70 pg/mL
Standard 7.6-42.6 pg/mL
The main difference I can see is the "sensitive" assay is a test where low levels of E2 are expected.
Has anyone had labs, testing both to see if the numbers are close?
