LEARN MORE ************** To learn more about this topic, start your googling with these keywords: Early Pregnancy Test: A simple lateral flow assay that tests for the presence of a particular hormone in urine. Lateral Flow Assay: Simple tests in which a liquid sample is run along the surface of a pad using capillary action and colored antibodies to show a visual positive or negative result. Capillary Action: The movement of water-based liquids within small tubes due to the forces of cohesion, adhesion, and surface tension. Antibody: A blood protein produced by the immune system in response to a particular antigen. Antigen: A foreign substance which produces an immune response within the body. False positive: A result produced that falsely indicates a particular antigen is present. False negative: A result produced that falsely indicates that a particular antigen is absent.
