What Macroprolactin measures
Macroprolactin testing separates active prolactin from large inactive complexes that can make a prolactin result look high.
If your Macroprolactin is low
A low monomeric prolactin is not usually a concern.
Commonly associated with
- Typical
If your Macroprolactin is high
Monomeric prolactin above the range means the active form is genuinely elevated, commonly associated with medications, stress, thyroid function or a pituitary source.
Commonly associated with
- Antipsychotic or anti-nausea medications
- Stress or poor sleep
- Underactive thyroid
- Pituitary source
- Pregnancy or breastfeeding
Typical reference range
| Group | Typical range |
|---|---|
| Women | 4.8 – 23.3 ng/mL |
| Men | 4 – 15.2 ng/mL |
Typical adult values used by many US labs. Your own report prints the range your lab validated for its method, and that range is the one that counts. Labwise always uses the printed range first.
If it is within range
Your monomeric prolactin is within the range printed by your lab, which is commonly read as the earlier high prolactin being mostly inactive macroprolactin.
