Ulta Lab Tests

Prolactin Total and Monomeric Test

The Prolactin Total and Monomeric Test measures both overall prolactin and the biologically active monomeric fraction to help evaluate pituitary function. Elevated total levels may be due to prolactinomas, pituitary adenomas, or stress, while excess macroprolactin can cause falsely high results. This test helps distinguish true hyperprolactinemia from benign macroprolactinemia, guiding diagnosis of hormonal and reproductive disorders.

The Prolactin Total and Monomeric Test test contains 1 test with 2 biomarkers .

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).
