How our test process works!
Inhibin A is a tumor marker tests measure these blood hormone levels to help detect a rare ovarian granulosa cell tumor.
Risk Assessment:
- The test is mainly used for screening during pregnancy to assess the risk of fetal Down syndrome (trisomy 21)and trisomy 18.
- It can also be part of a larger group of tests, such as the quadruple screen or first trimester screen, which assess risk for these and other genetic conditions.
- Low levels of inhibin A may indicate a higher risk of these conditions, while high levels can suggest a lower risk.
- It may also be used in fertility evaluations, especially in the context of polycystic ovary syndrome (PCOS) or ovarian reserve testing.
Normal Range:
- The normal range for Inhibin A can vary depending on the laboratory and test method, but generally:
- In non-pregnant women (especially in reproductive age): Inhibin A levels vary based on menstrual cycle phase and ovarian function.
- In pregnant women: During the first trimester, the normal range is generally between 50–150 pg/mL. During the second trimester, it typically ranges from 30–100 pg/mL.
- Values may fluctuate throughout the menstrual cycle or pregnancy stages, so it is important to check these levels over time.
Interpretation:
- High Inhibin A levels: Could be seen in pregnancy-related conditions such as Down syndrome (trisomy 21) or pregnancy complications like preeclampsia. It may also be seen in ovarian tumors.
- Low Inhibin A levels: Can be associated with low ovarian reserve, indicating possible fertility challenges, or conditions like Turner syndrome.
- Normal levels generally suggest no elevated risk for conditions being tested for, but always needs to be interpreted in conjunction with other clinical findings.
Sample Type:
- The test is typically performed using a blood sample drawn from a vein in your arm.
Frequently Asked Question
Inhibin A testing involves collecting a blood sample from the patient, which is then analyzed in a laboratory using immunoassay techniques to measure the concentration of inhibin A in the blood.
Treatment for individuals with abnormal inhibin A levels depends on the underlying cause identified. In cases of ovarian dysfunction or impaired testicular function, treatment may involve assisted reproductive technologies (ART), hormone replacement therapy, or other interventions aimed at improving fertility outcomes. Treatment decisions are individualized based on the specific diagnosis and clinical circumstances.
In females, elevated levels of inhibin A may indicate ovarian dysfunction or the presence of ovarian tumors, while low levels may suggest decreased ovarian reserve. In males, abnormal levels of inhibin A may indicate impaired testicular function or decreased sperm production.
Inhibin A testing may be ordered as part of fertility assessments in females, particularly when evaluating ovarian function and predicting response to ovarian stimulation during ART procedures such as in vitro fertilization (IVF). In males, it may be ordered to assess testicular function and sperm production in cases of infertility or hormonal imbalances.
Inhibin A testing is performed to assess ovarian function in females and testicular function in males. It is often used as a marker of ovarian reserve and can help evaluate ovarian function in conditions such as polycystic ovary syndrome (PCOS), infertility, or during assisted reproductive technologies (ART).
Inhibin A testing can be performed in medical laboratories or healthcare facilities equipped with the necessary equipment and expertise. It is typically ordered by healthcare providers, such as reproductive endocrinologists or fertility specialists, based on clinical indications.
There are typically no special preparations required for inhibin A testing. However, it is essential to follow any instructions provided by the healthcare provider regarding fasting or medication restrictions, if applicable.
