Test Overview
Test Methodology

ELISA

Test Usage

As an aid in the diagnosis of granulosa cell tumors and mucinous epithelial ovarian tumors; monitoring of patients with granulosa cell tumors and epithelial mucinous-type tumors of the ovary known to overexpress inhibin B; and as an adjunct to follicle-stimulating hormone testing during infertility evaluation (an inhibin B level in the postmenopausal range is suggestive of a diminished or depleted ovarian reserve).

Reference Range *

Age and sex specific ranges provided with report.

* Reference ranges may change over time. Please refer to the original patient report when evaluating results.

Test Limitations

Do not interpret serum inhibin levels as absolute evidence of the presence or the absence of malignant disease; use results in conjunction with information from the clinical evaluation of the patient and other diagnostic procedures. Inhibin values fluctuate during the menstrual cycle. Inhibin levels in premenopausal women should be interpreted with caution. Tumor markers are not specific for malignancy and values may vary by testing methodology; the same method should be used to serially monitor patients.
