Lactose Differential Sheets

Two sheets of multiple-choice cases help you distinguish lactose intolerance from look-alikes such as cow’s milk protein allergy, galactosemia, giardiasis, inflammatory bowel disease, and congenital diarrhoeas. Click the answer choice for each row, then switch between the Q1–5 and Q6–10 tabs to compare patterns like age of onset, stool features, growth, and red flags.
