Overview
Other Diagnostic Studies
Stool Cultures
Stool cultures in adequate culture media, allow the correct identification of the pathogen responsible for the infectious diarrhea. The identification of the organism allow specific treatment of the disease, as well as appropriate follow-up recommendations.[1]
However, this test is not routinely performed due to its elevated cost, when compared with the accuracy of the results. Often times results from fecal cultures are delayed and show an elevated rte of false-negatives.[2]
Lactoferrin Testing
Some studies advocate the importance to test for fecal lactoferrin. This test is considered more sensitive than simple microscopic examination of PMN. However, its cost and high rate of false-positives in breast-fed children, limit its application.[1][3][2][4]
Colonoscopy
For some cases of bloody diarrhea of unknown origin, a colonoscopy is indicated. It contributes to the diagnosis by confirming or ruling out conditions such as ulcerative colitis or malignancy.[1]
