Abstract

Aim. Verapamil stimulation test was previously investigated as a tool for differential diagnosis of hyperprolactinemia, but with conflicting results. Macroprolactinemia was never considered in those previous studies. Here, we aimed to re-investigate the diagnostic value of verapamil in a population who were all screened for macroprolactinemia. Prolactin responses to verapamil in 65 female patients (age: 29.9 +/- 8.1 years) with hyperprolactinemia were tested in a descriptive, matched case-control study.
