lactose allergy - emi

[ArchivalUser]

what test can diagnose that? thanks in advance. my exam is in 4 days..

Diarrheal stool specimens have an increased osmotic gap and pH < 6.0


Hydrogen breath test: After ingestion of 50 g lactose, a rise in breath hydrogen of > 20 ppm within 90 minutes is a positive test


Empiric trial of a lactose-free diet for 2 weeks leads to resolution of symptoms

Good luck!
