Prolactin

Measure Your Prolactin Levels from Home

The Prolactin Blood Test measures the level of prolactin in your blood to help identify hormonal imbalances that may affect fertility, menstrual cycles, libido, breast milk production, and overall reproductive health. Elevated prolactin levels (hyperprolactinaemia) can occur in both women and men and may indicate underlying hormonal or pituitary gland disorders.

With the Repose Healthcare Prolactin Blood Test, you can conveniently collect a small blood sample at home and receive accurate laboratory results without needing to visit a clinic.

What Is Prolactin?

Prolactin is a hormone produced by the pituitary gland, located at the base of the brain. It plays an important role in stimulating breast development and milk production after childbirth. However, prolactin also affects reproductive hormones, fertility, menstrual function, and sexual health in both men and women.

While prolactin naturally increases during pregnancy and breastfeeding, abnormally high levels outside these situations may indicate a medical condition requiring further investigation.

Why Test Your Prolactin Levels?

A prolactin test can help investigate symptoms associated with hormonal imbalance and reproductive health issues.

Women may consider testing if they experience:
Irregular or absent menstrual periods
Difficulty becoming pregnant
Unexplained breast milk production (galactorrhoea)
Reduced libido
Vaginal dryness
Headaches or visual disturbances
Men may benefit from testing if they experience:
Erectile dysfunction
Reduced sex drive
Fertility problems
Low testosterone symptoms
Breast enlargement (gynaecomastia)
Unexplained fatigue

Frequently Asked Questions
What is a normal prolactin level?

Normal prolactin levels vary depending on age, sex, pregnancy status, and the laboratory reference range used. Your results report will provide the appropriate reference intervals for interpretation.

Can stress increase prolactin levels?

Yes. Physical and emotional stress can temporarily raise prolactin levels. For this reason, it is often recommended to avoid strenuous exercise and significant stress before sample collection.

Does high prolactin affect fertility?

Yes. Elevated prolactin levels can interfere with ovulation in women and testosterone production in men, potentially affecting fertility.

Can medications affect prolactin levels?

Certain medications, including antidepressants, antipsychotics, blood pressure medications, and hormone therapies, may increase prolactin levels.

Do I need to fast before taking the test?

Fasting is generally not required unless otherwise instructed. Please follow the sample collection guidance included with your kit.
