Macro Prolactin: Price, Purpose, Range & Reports

The Macro Prolactin test, often performed as part of an investigation into high prolactin levels (hyperprolactinemia), is a specialised procedure used to distinguish between biologically active prolactin and a large, inactive complex known as macroprolactin. Macroprolactin is a benign aggregate of prolactin bound to an antibody (usually IgG) that remains in the bloodstream for longer, causing falsely elevated total prolactin levels on standard laboratory assays. The process helps doctors avoid unnecessary treatment for high prolactin when the cause is simply this inactive complex, a condition called macroprolactinemia.

What is the Macro Prolactin Test?

The Macro Prolactin Test is a specialised blood test used to identify whether elevated prolactin levels are due to biologically inactive forms of the hormone, known as macroprolactin.
Macroprolactin is a large, complex form of prolactin that circulates in the blood but typically does not cause symptoms or affect bodily functions. In some people, routine prolactin tests may show high levels even though they have no signs of prolactin-related conditions like irregular periods, infertility, or milk production outside of pregnancy. This can lead to unnecessary concern or treatment.
The Macro Prolactin Test helps clarify this by separating macroprolactin from the active form of prolactin. If most of the prolactin in your blood is macroprolactin, your doctor may consider the result clinically insignificant, meaning no treatment is needed. However, if the active form is elevated, further evaluation may be required to check for conditions like prolactinomas (pituitary tumours) or hormonal imbalances.

What is the Macro Prolactin Test Price?

The Macro Prolactin test price is generally higher than a standard Prolactin test. This is due to the additional manual laboratory step required to isolate the active prolactin.
Factors influencing the cost include:

•    Specialised Procedure: The test involves a preliminary treatment step, most commonly Polyethene Glycol (PEG) precipitation. This process separates the large, inert macroprolactin from the small, biologically active monomeric prolactin, adding complexity and cost compared to a direct immunoassay.
•    Time and Resources: The specialised handling, including incubation and centrifugation steps specific to the precipitation process, requires extra time and trained technical personnel.
•    Lab Accreditation and Location: Testing at NABL-accredited laboratories, like those affiliated with Apollo, ensures high precision and adherence to the strict protocols required for this multi-step assay.

What is the Purpose of the Macro Prolactin Test?

The primary purpose of the Macro Prolactin test is to confirm or exclude macroprolactinemia as the cause of hyperprolactinemia.
Doctors recommend this test for the following key objectives:

1.    Preventing Misdiagnosis: To identify patients with high total prolactin who are actually asymptomatic and do not have a true prolactin disorder (like a prolactinoma tumour).
2.    Guiding Treatment: True hyperprolactinemia (due to active monomeric prolactin) requires clinical intervention (medication or imaging), whereas macroprolactinemia is benign and requires no treatment, saving the patient from unnecessary medication and follow-up scans.
3.    Investigating Discrepancies: It is used when a patient has very high total prolactin but shows none of the typical symptoms (e.g., irregular periods, galactorrhea, infertility, or low libido).

Who Should Get a Macro Prolactin Count Done?

The Macro Prolactin test is not part of routine blood work. It’s usually recommended after a standard prolactin test shows high levels, especially when symptoms don’t match the results. This test helps determine whether the elevated prolactin is due to a harmless form called macroprolactin, which typically doesn’t cause symptoms or require treatment.

You may be advised to take this test if:

•    You have high prolactin levels but no symptoms: If your blood test shows elevated prolactin but you don’t have signs like irregular periods, milk discharge (galactorrhea), or sexual dysfunction, this test can help rule out macroprolactinemia.
•    Your prolactin levels are mildly elevated and persistent: If your levels are slightly high but not high enough to suggest a pituitary tumour, the test may help avoid unnecessary scans or medications.
•    You’re undergoing fertility treatment: High prolactin can interfere with ovulation and menstrual cycles. If your total prolactin is high but the active form is normal, prolactin may not be the cause of fertility issues.
•    You’re on medication for high prolactin: If you’re being treated with drugs like cabergoline or bromocriptine but your prolactin levels aren’t dropping as expected, macroprolactin may be responsible for the persistently high readings.
•    You’re being evaluated for a pituitary tumour (prolactinoma): Before ordering imaging tests like an MRI, your doctor may want to confirm that the elevated prolactin is truly active and not due to macroprolactin.
•    You have unexplained menstrual changes or hormonal symptoms: If your symptoms suggest a hormonal imbalance but don’t fully align with high prolactin levels, this test can help clarify the picture.

Components of the Macro Prolactin Test

The Macro Prolactin procedure provides several key values critical for diagnosis:
1.    Total Prolactin (Pre-PEG): The initial measurement of all prolactin forms (active and inactive) in the sample. This is the value that triggers the need for the macroprolactin test.
2.    Monomeric Prolactin (Post-PEG): The measurement of the active, small prolactin form remaining in the sample after the inert macroprolactin has been removed by precipitation. This is the biologically relevant value.
3.    Recovery Percentage: The calculated percentage of monomeric prolactin compared to the total prolactin. This is the diagnostic marker used to define macroprolactinemia.

Understanding a Macro Prolactin Report: Range & Interpretation

The interpretation of the Macro Prolactin test focuses on the Recovery Percentage.
Typical Reference Range for Monomeric Prolactin (Post-PEG)
The post-PEG result (monomeric prolactin) should fall within the normal range for active prolactin.

Preparation and Procedure for Macro Prolactin Test

The procedure for the Macro Prolactin test involves a standard blood draw; however, preparation is crucial due to prolactin's sensitivity to external factors.

1. How is the Test Done?

The test requires a routine blood sample (venipuncture), usually collected from a vein in your arm. The blood sample is then sent to the lab, where a portion is treated with PEG to precipitate the macroprolactin before the final measurement is taken.

2. Is Fasting Required for This Test?

Fasting is generally not required, but certain preparations are crucial for accurate results:
•    Avoid Strenuous Exercise: Do not engage in heavy exercise for at least 12 hours before the test.
•    Limit Stress: Emotional stress can temporarily raise prolactin levels; try to relax before the blood draw.
•    Optimal Timing: Due to the body's natural circadian rhythm, prolactin levels are highest shortly after waking. The sample should ideally be collected 3 to 4 hours after waking (e.g., mid-morning).

3. What Time of the Day Should I Undergo the Test?

The most critical factor is the timing relative to waking. A mid-morning collection time (around 9 AM to 12 PM) is preferred to avoid the natural early morning peak of prolactin secretion.

4. How Frequently Should I Undergo the Test?

The Macro Prolactin test is typically a one-time diagnostic test. If macroprolactinemia is confirmed (low recovery percentage), the patient is usually discharged from further endocrinological investigation for high prolactin.

Conclusion

The Macro Prolactin test is a critical, specialised tool that provides the clarity needed to accurately diagnose or rule out true hyperprolactinemia. By identifying the often-benign condition of macroprolactinemia, this test prevents unnecessary diagnostic procedures, high-cost imaging (like MRI), and potentially prolonged, unwarranted drug treatment for patients who are otherwise healthy.
