Tests for occult in stools of children.
Three tests for the presence of occult blood in the stools of children were examined; the orthotolidine test, the guaiacum resin test, and a modified reduced phenolphthalain test. The stools of 71 neonates, 33 normal children, and 8 children with suspected gastrointestinal pathology were examined. The 1% orthotolidine test and the guaiacum resin test produced a high number of false positive results in healthy children eating a meat-containing diet. It is concluded that a positive result by these tests is of little diagnostic value in children eating a normal diet.
