Inhibin A (Dimer)
Also known as: INHIBA
Use
The Inhibin A (Dimer) test aids in the diagnosis and monitoring of various hormonal reproductive disorders. Elevated levels of Inhibin A may indicate conditions such as preeclampsia, Down Syndrome, and certain cancers. The test measures the concentration of Inhibin A, which is a hormone involved in the regulation of the reproductive system, particularly linked to ovarian function in females and potentially affected by various clinical conditions.
Special Instructions
Fasting specimens are recommended but not required for this test. It is important to follow the proper specimen preparation and handling procedures to ensure the accuracy of the results. The test is conducted using a Serum Separator Tube and transported in an ARUP Standard Transport Tube. It is crucial to avoid repeated freeze/thaw cycles when handling the specimen.
Limitations
The Inhibin A (Dimer) test is specific to measuring this particular hormone and does not provide information on other potential biomarkers or conditions. Values obtained from this test may be elevated during normal pregnancy, and thus clinical interpretation should consider the patient's pregnancy status. Additionally, interferents such as hemolyzed or severely lipemic specimens can be unacceptable and affect the test results.
