Lactose Intolerance

Tests & Diagnosis

The simplest, and probably most reliable, way of diagnosing lactose intolerance is to remove all lactose products from your diet for 1 - 2 weeks and see if your symptoms disappear.  If the symptoms do disappear, a diet that does not include lactose should be maintained.

There are other tests available when the response to lactose exclusion is not clear. These include blood tests, hydrogen breath test and stool acidity test for young children.
