How to Check Prolactin Levels?

Update Date: Source: Network

Checking prolactin can be done on the second or third day of menstruation on an empty stomach at a hospital. Here are some details:

1. prolactin check-up time

The most accurate time for prolactin testing is to draw venous blood on an empty stomach in the morning of the second or third day of menstruation. Prolactin is a polypeptide hormone, also known as prolactin (PRL), which is one of the hormones secreted by the pituitary gland. Prolactin is secreted by specialized cells concentrated on both sides of the posterior pituitary gland, originating from the same cells as growth hormone.

2. How to do prolactin testing

1. Check estrogen (estradiol), progesterone, and follicle-stimulating hormone, which are also examined after venous serum separation, requiring 2 milliliters each.

2. To check luteinizing hormone, although it is also checked by radioimmunoassay, as luteinizing hormone is secreted in a pulsed manner, it is best to collect samples 3-4 times within 1 hour and then mix them together for measurement to ensure more accuracy.

3. Prolactin should be checked on an empty stomach, with serum drawn around 9 am.

4. Do not take sexual hormone drugs randomly before the test. If taken, the test should be performed after the hormones are completely excreted to avoid misdiagnosis.

5. Pay attention to the specific time of the test, medication before the test, and some special methods during the test.

6. Individuals with abnormal reproductive organs and suspected endocrine diseases should undergo a six-item serum endocrine examination to facilitate early diagnosis and provide a basis for subsequent treatment.
