Monomeric Prolactin details
What Monomeric Prolactin shows
Monomeric prolactin is the normal, fully active, single-molecule form of prolactin — as opposed to macroprolactin, a larger and less biologically active form that can also show up in a standard prolactin test. Measuring monomeric prolactin specifically helps clarify whether an elevated total prolactin result is driven by genuinely active hormone (which would warrant further evaluation for causes like a pituitary tumor or certain medications) or largely by the less clinically significant macroprolactin form.
Tests that include Monomeric Prolactin
This test is used to determine biologically active levels of prolactin in asymptomatic patients with elevated prolactin levels.
- Monomeric Prolactin The active, single-molecule form of prolactin, distinguished from macroprolactin (a larger, less active form) to clarify the true cause of an elevated prolactin result.
- Prolactin A pituitary hormone best known for stimulating milk production; also checked to evaluate menstrual irregularities, fertility issues, or pituitary conditions in men and women.
- Macroprolactin/Prolactin The percentage of your prolactin that's in a large, less biologically active form. Helps determine whether an elevated prolactin result is clinically significant.
For some patients the level of Prolactin measured by immunoassay may be inaccurate with respect to the level of monomeric, biologically active Prolactin. The Macroprolactin by PEG Precipitation test can help to identify if a patient sample has elevated Prolactin due to mostly inactive protein-bound Prolactin (Macroprolactin).
- Monomeric Prolactin The active, single-molecule form of prolactin, distinguished from macroprolactin (a larger, less active form) to clarify the true cause of an elevated prolactin result.
- Prolactin A pituitary hormone best known for stimulating milk production; also checked to evaluate menstrual irregularities, fertility issues, or pituitary conditions in men and women.
