Official Description

Hydroxyprogesterone, 17-d

© Copyright 2026 American Medical Association. All rights reserved.

Common Language Description

The CPT® Code 83498 refers to the measurement of 17-hydroxyprogesterone (17-OHP), a hormone that plays a crucial role in the body's endocrine system. This test is typically performed through a blood or urine sample to assess the levels of 17-OHP, which is primarily produced in the adrenal glands and the corpus luteum of the ovary. The measurement of 17-OHP is particularly significant in the context of congenital adrenal hyperplasia (CAH), a genetic disorder that affects adrenal gland function, as elevated levels of this hormone can indicate the presence of this condition in infants. Consequently, the 17-OHP test is often included in newborn screening panels to ensure early detection and management of CAH. In adults, the levels of 17-OHP can be influenced by various factors, including the presence of adrenal and ovarian tumors, polycystic ovarian syndrome (PCOS), and physiological changes during pregnancy, particularly in the third trimester. The test can be performed using a blood sample obtained through venipuncture, which is a standard method for collecting blood. For infants, a less invasive approach, such as the heel stick or capillary method, may be utilized to draw blood. The analysis of the collected serum or plasma is typically conducted using advanced techniques such as quantitative high-performance liquid chromatography-tandem mass spectrometry or quantitative radioimmunoassay, which provide accurate measurements of hormone levels. Alternatively, a 24-hour urine specimen may be collected and analyzed using radioimmunoassay, offering another method for assessing 17-OHP levels in the body.

1. Indications

The 17-hydroxyprogesterone (17-OHP) test is indicated for several clinical scenarios, particularly in the evaluation of hormonal imbalances and conditions related to adrenal and reproductive health. The following are the primary indications for performing this test:

  • Congenital Adrenal Hyperplasia (CAH) - This test is crucial for screening newborns for CAH, a genetic disorder that can lead to serious health issues if not identified early.
  • Adrenal Tumors - Elevated levels of 17-OHP may suggest the presence of tumors in the adrenal glands, necessitating further investigation.
  • Ovarian Tumors - Similar to adrenal tumors, abnormal levels of 17-OHP can indicate potential ovarian tumors that require additional diagnostic evaluation.
  • Polycystic Ovarian Syndrome (PCOS) - The test may be used to assess hormonal levels in women suspected of having PCOS, a condition characterized by hormonal imbalance and metabolic issues.
  • Pregnancy (3rd Trimester) - Monitoring 17-OHP levels during the third trimester of pregnancy can provide insights into the hormonal changes occurring in the body.

2. Procedure

The procedure for measuring 17-hydroxyprogesterone (17-OHP) involves several key steps to ensure accurate results. The following outlines the procedural steps involved:

  • Step 1: Sample Collection - For adults, a blood sample is typically obtained through venipuncture, where a needle is inserted into a vein to draw blood. In infants, a less invasive method, such as a heel stick or capillary method, is employed to collect the blood sample. This approach minimizes discomfort and is suitable for newborns.
  • Step 2: Sample Preparation - Once the blood sample is collected, it is processed to separate the serum or plasma, which is necessary for the subsequent analysis. This step is crucial as it ensures that the sample is suitable for testing.
  • Step 3: Laboratory Analysis - The prepared serum or plasma is then analyzed using quantitative high-performance liquid chromatography-tandem mass spectrometry or quantitative radioimmunoassay. These advanced techniques provide precise measurements of 17-OHP levels in the sample.
  • Step 4: Alternative Urine Collection - Alternatively, a 24-hour urine specimen may be collected from the patient. This method involves collecting all urine produced over a 24-hour period, which is then tested using radioimmunoassay to measure 17-OHP levels.

3. Post-Procedure

After the procedure, patients may be advised on specific post-collection care, particularly if venipuncture was performed. It is common for patients to experience minor discomfort or bruising at the site of blood draw, which typically resolves on its own. For infants, caregivers should monitor the heel stick site for any signs of excessive bleeding or infection. Results from the 17-OHP test are usually available within a few days, and healthcare providers will discuss the findings with the patient or the infant's caregivers to determine any necessary follow-up actions or treatments based on the results. It is important to note that further testing may be required if abnormal levels of 17-OHP are detected, to confirm a diagnosis or to rule out other conditions.
