Rapid test for determination of disaccharidase activities in endoscopic biopsy specimens from the small intestine.
We have developed a new and rapid semiquantitative method of demonstrating disaccharidase activities in biopsy specimens obtained endoscopically from the jejunum. Biopsy samples are placed in sucrose or lactose solutions. Sucrase and lactase activities are detected by testing glucose in the solutions using commercial urine glucose detection strips.
