What is being tested?

The prolactin test’s purpose is to check the prolactin hormone quantity in the blood specimen and help diagnose conditions that cause abnormal levels of the prolactin hormone. Prolactin (PRL) is a significant hormone in the body that has many functions.

Preparation needed?

Sleep problems and high-stress levels can affect the results of the PRL test. Moreover, liver and kidney disease raise the PRL level. Indulging in heavy exercise also influences the results of this test. Also, you must avoid consuming alcohol for 24 hours before submitting the blood sample. It is also recommended to submit the sample in 3 to 4 hours after waking up, preferably before noon, as the prolactin level is generally more during the evening because of the circadian rhythm.

If you need to take a blood sample from an infant for testing, the lab worker guides you about its specific preparation and process. In newborns, a blood sample is taken from the umbilical cord. 

This test uses the immunoassay methodology. Immunoassay is a systematic method in medical diagnostic testing to measure or detect particular substances or proteins by analyzing their unique antibodies or antigens. 

Fasting required?
