Inhibin A assay.
Modifiers may be applicable, such as modifier 91 (Repeat Clinical Diagnostic Laboratory Test) if the test needs to be repeated due to specimen issues or other valid reasons.
Medical necessity for Inhibin A testing is generally established by the patient's pregnancy and the desire for Down syndrome risk assessment.Specific guidelines may vary depending on payer policies and the patient's individual risk factors.
Laboratory professionals perform the Inhibin A assay, analyzing serum separated from a blood sample. This involves methodologies such as radioimmunoassay, comparing the results to gestational age-specific median values to determine risk factors for Down syndrome.
In simple words: This blood test measures the level of Inhibin A hormone during pregnancy.It's part of a group of tests used to assess the risk of Down syndrome in the baby.
This code represents a quantitative measurement of Inhibin A levels, typically performed on pregnant women's serum as part of a multiple marker screening test for Down syndrome and other fetal abnormalities.The test measures the exact amount of Inhibin A in the blood.
Example 1: A pregnant woman in her second trimester undergoes a multiple marker screening which includes an Inhibin A assay, along with AFP, hCG, and estriol, to assess the risk of Down syndrome for her fetus., A woman with a family history of Down syndrome elects for additional screening measures during her pregnancy, and her physician orders an Inhibin A test as part of the screening panel., Following abnormal results from an initial screening test, a pregnant woman is offered a second trimester screening, including Inhibin A, to further evaluate the risk of fetal abnormalities.
Documentation should include the reason for the test (e.g., routine screening, family history), gestational age, date and time of sample collection, and the results of the Inhibin A assay, typically reported as multiples of the median (MoM).The report should also include the interpretation of the results in the context of other screening tests performed.
** While Inhibin A is primarily used in prenatal screening, it can also have applications in other contexts, such as monitoring certain types of ovarian tumors. However, code 86336 specifically pertains to its use in pregnancy-related screening for fetal abnormalities.
