Quantitative Chemiluminescent Immunoassay
Specimens from New York clients will be sent out to a New York DOH approved laboratory, if possible.
If the % Monomeric Prolactin is 40-50%, then the result is indeterminate for macroprolactin. If the % Monomeric Prolactin is less than 40%, then this indicates the presence of macroprolactin. A Monomeric Prolactin result above the upper reference limit is consistent with hyperprolactinemia.
Monomeric Prolactin was determined by PEG precipitation. Macroprolactin is precipitated by PEG and is not measured.
