Este protocolo descreve a análise da morfologia organoide retal (ADM), um novo ensaio diagnóstico para fibrose cística (FC). As características morfológicas, nomeadamente a arredondamento (índice de circularidade, IC) e a presença de um lúmen (razão de intensidade, RI), são uma medida da função CFTR. A análise de 189 sujeitos mostrou perfeita discriminação entre FC e não FC.
