Clinical Application
Occasionally patients may produce a benign/non-biologically active form of prolactin bound to IgG, termed MACROPROLACTIN. The presence of macroprolactin causes monomeric prolactin to be over-estimated by routine analysis. Biochemistry clinicians review all raised prolactin results and may order an in-house screening test to be performed which will indicate the presence or absence of macroprolactin.

Please contact a Biochemist should you wish to discuss macroprolactin analysis (x4711/13/15 or x6075).
