[The value of hyperprolactinemia determination within the scope of galactorrhea]

Of 210 women with galactorrhea 66.2% had normal prolactin serum levels. Only in 33.4% elevated prolactin levels could be found, 0.4% were hypoprolactinemic. The TRH-stimulation test detected latent hyperprolactinemia in 13.5% of the cases, showed a normal thyroid function in 81.5%, hypothyroidism in 13.9% and hyperthyroidism in 4.6% and this is considered to be a more valuable diagnostic tool than the MCP-test. Galactorrhea was associated with the following conditions: hyperprolactinemia (34.8%), menstrual disturbances (67.4%), post-pill amenorrhea (30.2%), mastalgia (30.2%), prolactinoma (18.6%), fibrocystic disease (11.6%), hirsutism (4.6%), diabetes mellitus (2.3%).
