Name of the Procedure:

Pregnanediol Test

Summary

The Pregnanediol test is a diagnostic procedure used to measure the levels of pregnanediol, a metabolite of progesterone, in a patient's urine. This helps healthcare providers assess and monitor the function of the corpus luteum in women, which plays an essential role in fertility and menstrual health.

Purpose

The Pregnanediol test is used primarily to:

• Assess ovarian function.
• Monitor the effectiveness of fertility treatments.
• Determine the cause of irregular menstrual periods.
• Evaluate early pregnancy health and potential complications.

Indications

• Irregular or absent menstrual cycles.
• Infertility investigations.
• Monitoring after treatments for conditions affecting ovulation.
• Suspicion of luteal phase defects.
• Early pregnancy assessments in high-risk situations.

Preparation

• Patients may be asked to collect a 24-hour urine sample.
• No specific fasting or medication adjustments are typically required.
• It is advisable to inform the healthcare provider of any medications or supplements being taken.

Procedure Description

1. The patient is provided with a container for urine collection and instructions on how to collect all urine over a 24-hour period.
2. The urine sample is returned to the healthcare provider or laboratory for analysis.
3. The laboratory performs a chemical analysis to measure the levels of pregnanediol.

Duration

• The collection period spans 24 hours.
• Laboratory analysis generally takes a few days to process results.

Setting

• The urine collection is done at home or in an outpatient setting.
• Analysis is conducted in a medical laboratory.

Personnel

• Primary care physician, gynecologist, or fertility specialist orders and interprets the test.
• Laboratory technicians conduct the urine analysis.

Risks and Complications

• There are no direct risks or complications associated with the Pregnanediol test itself.
• Poor sample collection may lead to inaccurate results, and a repeat test may be necessary.

Benefits

• Provides valuable information on ovarian function and progesterone levels.
• Helps tailor fertility treatments and monitor their efficacy.
• Enhances understanding of menstrual irregularities and related conditions.

Recovery

• No recovery time is required as this is a non-invasive test.
• Follow-up appointments may be necessary to discuss test results and potential treatments.

Alternatives

• Blood tests to measure progesterone levels.
• Ultrasound to assess ovarian activity and endometrial lining.
• Luteinizing hormone (LH) testing for ovulation monitoring.

Patient Experience

• The patient may feel the task of collecting urine for 24 hours to be somewhat inconvenient but painless.
• No pain management is required for this non-invasive test.
