Kimia AA, et al. - In this work, authors aim to determine the predictive value of GI bleeding (positive guaiac test, bloody stool and rectal bleeding) in evaluation of intussusception. They realize that blood in stool, whether visible or tested by guaiac test has poor diagnostic performance. It was not independently predictive of intussusception. If the sole purpose of a rectal exam in these patients is for guaiac testing it should be reconsidered.
