Hemoglobin.gastrointestinal.lower^1st specimen

This test detects the presence of hemoglobin (blood) in stool samples, which may indicate bleeding in the lower gastrointestinal tract. Blood in stool can originate from the colon, rectum, or anus and may result from various conditions including hemorrhoids, polyps, inflammatory bowel disease, diverticulosis, or infections. Visible blood appears red or dark, while microscopic blood is only detectable by laboratory testing. This test helps identify gastrointestinal bleeding and guide further diagnostic evaluation if needed.
