Na abordagem diagnóstica da hiperprolactinemia, três armadilhas ou problemas potenciais merecem uma atenção especial: os incidentalomas hipofisários (presentes em 10% da população adulta à ressonância magnética), o efeito gancho e a macroprolactinemia. O efeito gancho se caracteriza pela presença de níveis falsamente baixos de prolactina (PRL), quando se empregam imunoensaios de dois sítios em pacientes com grandes prolactinomas e hiperprolactinemia muito acentuada. O efeito gancho pode ser identificado através de uma nova dosagem da PRL após diluição do soro a 1:100, quando se observará um aumento dramático do valor da PRL. Ele deve ser excluído em qualquer paciente com um macroadenoma e níveis séricos de PRL <200ng/mL. A macroprolactinemi...
