Laboratory Studies

Laboratory studies are usually not indicated in colic unless the physician suspects another condition, such as gastroesophageal reflux.

If the patient's stools are excessively watery, testing them for excess reducing substances (Clinitest) may be worthwhile. If results are positive, this may be an indication of an underlying gastrointestinal problem, such as acquired (postinfectious) lactose intolerance. Stool may be tested for occult blood to rule out cow's milk allergy (CMA).

Irritability and crying may be associated with gastroesophageal reflux disease because of the pain associated with esophagitis.
