Hormones are mighty chemical messengers that regulate virtually all body processes. When hormones fall out of balance, it can wreak havoc on both physical and mental health. Prolactin is one such key hormone with wide-ranging roles in reproduction, metabolism, and immunity.
Abnormal prolactin levels serve as red flags for underlying issues warranting further medical investigation. Quantifying prolactin through blood tests allows for early detection of hormonal dysfunction, paving the way for timely diagnosis and treatment.
What is Prolactin?
Prolactin is a protein-based hormone produced in the pituitary gland situated at the base of the brain. As the name suggests, prolactin primarily functions to initiate and sustain milk synthesis in new mothers after childbirth.
However, prolactin regulates over 300 separate processes in the body beyond lactation, including metabolism, fertility, cell growth, and immune regulation in both women and men.
Common Reasons of Prolactin Test
Doctors may advise prolactin test for several key reasons:
1. Fertility Investigations
Abnormal prolactin levels can impair fertility and reproductive functioning in both men and women. Elevated or suppressed levels affect factors like egg maturation, ovulation, sperm production and sexual drive. Testing identifies reversible hormonal imbalances hindering conception and allows treatment to improve fertility odds.
2. Diagnosing Pituitary Tumours
Prolactin originates in the pea-sized pituitary gland at the base of the brain. Excessively high prolactin levels often signal prolactin-secreting tumours in the gland called prolactinomas. Testing is crucial for early tumour detection to enable prompt treatment and preservation of surrounding brain structure and function.
3. Understanding Menstrual Problems
The menstrual cycle relies on delicate hormonal balance. Prolactin interacts with key female hormones like estrogen and progesterone that coordinate menstrual cycles. Elevated prolactin throws off this balance, causing absent, irregular, or heavy periods. Testing guides suitable treatment to restore rhythm.
4. Evaluating Unusual Nipple Discharge
Unexpected nipple discharge can result from changes in prolactin. Testing determines if hormonal shifts underlie discharge in both men and women, guiding appropriate corrective therapy.
5. Symptom Evaluation
Numerous concerning symptoms like vision changes, headaches, loss of libido, or breast milk secretion can sometimes indicate prolactin abnormalities. Testing is warranted to pinpoint if hormonal dysfunction is the culprit to enable suitable management.
Who Should Get a Prolactin Test?
If you’re unsure whether a prolactin test is relevant for you, these common scenarios can offer some clarity.
You may need a prolactin test if:
- You are facing challenges in getting pregnant.
- Your periods are irregular or have stopped.
- You notice unexplained nipple discharge.
- You have symptoms pointing towards pituitary dysfunction.
- Your doctor has recommended hormone level evaluation.
Men, too, can experience symptoms such as low libido, infertility, or nipple discharge, which might be linked to elevated prolactin levels.
How are Prolactin Tests Performed?
A simple blood test measuring prolactin forms the cornerstone of diagnosis. After an overnight fast, a small blood sample will be collected by needle puncture of a vein, usually in the arm. An elastic band tied around the upper arm helps engorge the veins with blood to enable easy needle insertion.
The preferred analysis method involves immunoassays that utilise antibodies to detect and quantify prolactin levels down to nanograms. Two formats include:
- ELISA (Enzyme-linked immunosorbent assay): Employs enzymes and colour changes to confirm and measure prolactin visually.
- Chemiluminescent assays: Detect light emitted when antibody-prolactin binding occurs to quantify levels.
These assays provide an easy, rapid, and economical technique for accurate hormonal profiling.
Interpreting Prolactin Test Results
Reference ranges to help interpret prolactin test findings are:
Females:
Non-pregnant: 2.8 – 29.2 ng/ml
Pregnant: 9.7 – 208.5 ng/ml
Males: 2.1 – 17.7 ng/ml
Higher than normal results indicate excess prolactin production (hyperprolactinemia) while lower levels signal reduced output (hypoprolactinemia).
What if Your Prolactin Levels are High?
High prolactin levels (also known as hyperprolactinemia) can be linked to several causes:
- Prolactinoma: A benign tumour on the pituitary gland.
- Thyroid Disorders: An Underactive thyroid may influence prolactin production.
- Certain Medications: Drugs affecting dopamine levels can raise prolactin.
- PCOS: Women with this condition may show mildly elevated levels.
- Pregnancy and Lactation: Naturally causes higher prolactin readings.
What if Your Prolactin Levels are Low?
While rare, low prolactin levels (hypoprolactinemia) may indicate:
- Pituitary Issues: Hypopituitarism may affect hormone production
- Medication Side Effects: Some drugs used in neurological disorders can suppress prolactin.
- Nutritional Deficiencies or Stress: In some cases, extreme physical or emotional stress plays a role.
Your doctor will evaluate these results in context to determine if further tests or interventions are necessary.
