High Rate of Positive Fecal Occult Blood Test in Healthy Infants: A Nested Case-control Study Guaiac fecal occult blood test (gFOBT) is often used to evaluate evidence of food protein-induced allergic proctocolitis (FPIAP) in children in primary care and gastroenterology settings; however, it has not been validated for this diagnosis, and little is known about the positivity rates in early infancy. In this study, we used samples from healthy asymptomatic infants aged two weeks to two months to evaluate the gFOBT positivity rate compared to those diagnosed with FPIAP.

🔬 Positive gFOBT isn’t rare even in healthy infants: this study found positivity in asymptomatic early infancy, a reminder that occult blood alone shouldn’t drive FPIAP diagnosis.
