Inhibin A
CPT4 code
Name of the Procedure:
Inhibin A Test
Summary
An Inhibin A test is a blood test that measures the levels of the hormone inhibin A in the blood. This hormone is produced by the ovaries in women and is typically used in combination with other tests to screen for certain pregnancy-related conditions and ovarian function.
Purpose
The Inhibin A test is used mainly during pregnancy to screen for chromosomal abnormalities in the fetus, such as Down syndrome. It can also be used to monitor ovarian function and diagnose certain ovarian tumors.
Indications
- Screening for chromosomal abnormalities (e.g., Down syndrome) during pregnancy.
- Diagnosing and monitoring certain types of ovarian cancers.
- Assessing ovarian function in women experiencing fertility issues.
Preparation
- No fasting is typically required.
- Inform the doctor about any medications or supplements being taken as they might affect the test results.
- Specific instructions may be provided based on the individual's health condition.
Procedure Description
- The patient's arm is cleaned with an antiseptic wipe.
- An elastic band is placed around the upper arm to fill the veins with blood.
- A needle is inserted into a vein, usually on the inside of the elbow.
- Blood is drawn and collected into a vial or tube.
- The needle is removed, and a bandage is applied to the site.
- The blood sample is sent to a laboratory for analysis.
No anesthesia or sedation is required for a blood draw procedure.
Duration
The blood draw procedure takes about 5-10 minutes. Laboratory results may take a few days.
Setting
The procedure is typically performed in a medical office, outpatient clinic, or hospital laboratory.
Personnel
- Registered nurse (RN) or phlebotomist to draw the blood.
- Laboratory technicians to analyze the blood sample.
Risks and Complications
- Minor bruising or discomfort at the needle site.
- Rarely, infection or excessive bleeding.
- Dizziness or fainting during the blood draw.
Benefits
- Early detection of potential chromosomal abnormalities in a fetus.
- Monitoring of ovarian function and detection of certain ovarian tumors.
- Non-invasive and quick procedure.
Recovery
- Patients can return to normal activities immediately.
- Keep the bandage on for a few hours to prevent bleeding.
- Follow any additional instructions from the healthcare provider.
Alternatives
- For pregnancy screening: Other biochemical screening tests, ultrasound, or amniocentesis.
- For ovarian function: Additional hormonal assays or imaging tests.
- Each alternative has its own pros and cons in terms of accuracy, invasiveness, and associated risks.
Patient Experience
- The patient may feel a slight pinch or sting when the needle is inserted.
- Mild soreness or bruising at the site of the blood draw might occur but typically resolves quickly.
- Most patients experience minimal discomfort and can resume normal activities immediately following the procedure.
