Macroprolactin

What is Macroprolactin?

Macroprolactin is a high-molecular-weight, biologically inactive form of the hormone prolactin. Unlike the active form, macroprolactin does not typically cause symptoms or affect normal hormonal function.

Purpose of Macroprolactin Testing

The macroprolactin blood test is used to differentiate between true hyperprolactinemia and elevated prolactin levels caused by inactive macroprolactin. This is especially useful in asymptomatic patients who show elevated total prolactin levels but do not display symptoms commonly associated with high prolactin, such as menstrual irregularities, infertility, or galactorrhoea.

Importance in Hormonal Assessment

Identifying macroprolactin helps avoid unnecessary investigations or treatments by clarifying whether the elevated prolactin is biologically active or not. It ensures accurate diagnosis and prevents misinterpretation of hormonal results.
