There is no test to diagnose IBS-D, so doctors often use blood and stool tests to rule out other diseases before reaching an IBS-D diagnosis. Rome IV criteria can be used to diagnose IBS-D based on the proportion of bowel movements rated as diarrhea compared to those rated as normal.[1] Symptoms need to occur at least once per week for at least three months to be considered IBS.[2]
