Prolactin Test Means

  • A prolactin test is a blood test that measures the level of prolactin hormone in your blood.
  • Prolactin is produced by the pituitary gland and plays a role in regulating lactation, as well as other reproductive functions in both men and women.
  • Abnormal levels of prolactin can be a sign of certain medical conditions, such as pituitary tumors or hypothyroidism.
  • A prolactin test may be used to diagnose these conditions, as well as monitor the effectiveness of treatment.
  • The test is typically performed by drawing a blood sample from a vein in your arm, and the results are usually available within a few days.

 

Prolactin Test Purpose

Here are some points explaining the purpose of a prolactin test:

  • The primary purpose of a prolactin test is to measure the level of prolactin hormone in your blood to help diagnose medical conditions that affect prolactin levels.
  • High levels of prolactin can be a sign of certain medical conditions, such as a prolactinoma (a benign tumor in the pituitary gland), hypothyroidism, or liver or kidney disease.
  • A prolactin test can help diagnose these conditions, as well as monitor the effectiveness of treatment.
  • In women, a prolactin test may be used to diagnose the cause of infertility or irregular menstrual periods.

Measures The clotting ability of the intrinsic pathway of the coagulation cascade The clotting ability of the extrinsic pathway of the coagulation cascade
Normal range 25-35 seconds 11-13.5 seconds
Measures The time taken for fibrin clot formation The time taken for fibrinogen to be converted to fibrin

Prolactin Test Result

Here are some points explaining how to interpret the results of a prolactin test:

  • The results of a prolactin test are reported in nanograms per milliliter (ng/mL) or micrograms per liter (µg/L).
  • The normal range for prolactin levels varies depending on the laboratory performing the test, but generally ranges from 2 to 29 ng/mL for women and 2 to 18 ng/mL for men.
  • Elevated prolactin levels may indicate the presence of a prolactinoma, hypothyroidism, liver or kidney disease, or certain medications.
  • Lower-than-normal prolactin levels are less common but may be a sign of pituitary damage or malfunction.
  • Your doctor will interpret the results of your prolactin test and discuss any necessary follow-up or treatment with you.

Prolactin Test Normal Range

Here is the normal range for prolactin levels.

Age/Gender Normal Range
Women (non-pregnant) < 25 ng/mL
Pregnant Women 80 to 400 ng/mL
Men < 20 ng/mL

It is important to note that the normal range may vary slightly depending on the laboratory performing the test, and that your doctor will interpret the results of your prolactin test and discuss any necessary follow-up or treatment with you.

 

Prolactin Test Interpretation

Here are some possible interpretations of prolactin test results.

Prolactin Level Possible Interpretation
Less than 2 ng/mL or µg/L Lower-than-normal prolactin levels, which may be a sign of pituitary damage or malfunction.
< 25 ng/mL Normal prolactin levels.
30 to 200 ng/mL Moderately elevated prolactin levels, which may indicate the presence of a prolactinoma (a non-cancerous tumor in the pituitary gland). Further tests and imaging studies may be needed to confirm the diagnosis.
Greater than 200 ng/mL Markedly elevated prolactin levels, which strongly suggest the presence of a prolactinoma. Further tests and imaging studies may be needed to confirm the diagnosis.

 

Prolactin Test High

Here are some common causes of high prolactin levels:

Cause Description
Prolactinoma A noncancerous tumor in the pituitary gland that produces too much prolactin
Medications Certain medications such as antipsychotics, antidepressants, and high blood pressure medications can increase prolactin levels
Hypothyroidism An underactive thyroid gland can cause elevated prolactin levels
Stress Severe stress or physical exertion can temporarily increase prolactin levels
Pregnancy Prolactin levels naturally rise during pregnancy to support lactation
Breastfeeding Breastfeeding can also cause prolactin levels to increase
Other conditions Certain medical conditions such as kidney disease, liver disease, and PCOS (polycystic ovary syndrome) can also cause high prolactin levels

 

Prolactin Test Low

Low levels of prolactin are relatively rare, but here are some potential causes:

Cause Description
Medications Certain medications such as dopamine agonists and antipsychotics can decrease prolactin levels
Pituitary damage Trauma, surgery, radiation therapy, or other damage to the pituitary gland can reduce prolactin production
Sheehan's syndrome A condition in which the pituitary gland is damaged due to severe blood loss during childbirth
Anorexia nervosa Severe malnutrition and low body weight can reduce prolactin levels
Hypopituitarism A condition in which the pituitary gland doesn't produce enough hormones, which can include low prolactin levels
Other conditions Certain medical conditions such as tumors or cysts in the pituitary gland, adrenal gland disorders, and head injuries can also affect prolactin levels
