Which of the following tests is used to detect hidden blood in stool?

The Hemoccult test is specifically designed to detect hidden (occult) blood in stool, which can be indicative of underlying gastrointestinal issues, including colorectal cancer or bleeding from other sources in the digestive tract. This test works by applying a small sample of stool to a special card that contains a chemical that reacts with hemoglobin, allowing healthcare providers to identify blood that is not visible to the naked eye.

In contrast, the creatinine test is primarily used to assess kidney function by measuring the level of creatinine in the blood. The glucose test measures blood sugar levels and is commonly used to diagnose diabetes. The lipid panel assesses levels of cholesterol and triglycerides to evaluate heart health. Each of these tests serves a different purpose and does not have the capability to detect hidden blood in the stool like the Hemoccult test does.
