IMUNO-HISTOQUÍMICA
TUMOR DE MAMA - PAINEL PROGNÓSTICO

Avaliação de painel de marcadores prognósticos (Ki67, receptor de estrógeno, receptor de progesterona, HER2 e COX-2) em câncer de mama de cadelas e gatas com objetivo de melhor definir a estratégia terapêutica.

As amostras tumorais sujeitas aos testes de imuno-histoquímica para marcadores HER2, RE e RP devem ser fixados em formalina tamponada à 10% por pelo menos 6 horas, com no máximo 48 horas para HER2 e 72 horas para RE/RP.

O material requerido é o tecido fixado em formalina, de preferência tamponada, e incluído em parafina (bloco de parafina) com fragmento representando tumor mamário diagnosticado no exame histopatológico de rotina e cópia do relatório do patologista veterinário.

Prazo de Entrega do laudo 10 a 15 dias úteis
