Quizplus · Accepted Answer

A direct ELISA is used to detect the presence or absence of an antigen in a sample. In the case of a home pregnancy test kit, the kit contains antibodies that are specific to the pregnancy hormone human chorionic gonadotropin (hCG). When a urine sample is added to the kit, any hCG present will bind to the antibodies on the test strip, causing a reaction that produces a visible result. This is an example of a direct ELISA because the antigen (hCG) is being directly detected by the antibody on the test strip.
