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!

from the history that given by patient is the best soruce for dx, and then u can do elmination diet to see if patient get better....another one milk challenge test or hydrogen breath test....etc.....i beileve the diet elimination is our best approach as initial
perfect answers both of you! thanks a lot...
