What type of test is commonly referred to as a hemoccult test?

The commonly referred term "hemoccult test" pertains specifically to the fecal occult blood test. This type of test is designed to detect hidden blood in the stool, which can be an important indicator of various gastrointestinal issues, including colorectal cancer, ulcers, or polyps. The term "hemoccult" itself derives from the roots "hemo," meaning blood, and "occult," meaning hidden.

The fecal occult blood test involves applying a stool sample to a test card or similar device which will reveal the presence of blood through a chemical reaction. This reaction can be visually assessed or quantitatively measured to evaluate the presence of gastrointestinal bleeding that may not be apparent during visual inspection.

The other types of tests listed are utilized for different diagnostic purposes. Viral culture tests and bacterial culture tests are used to grow viral or bacterial pathogens from samples, while serological tests assess the immune response to specific antigens or pathogens in the blood. These tests do not relate to the detection of blood in stool and therefore do not fit under the term "hemoccult."
