| Description | Diagram of typical immunoassay home pregnancy test which detects human chorionic gonadotropin (hCG). (A) A urine sample is applied to the stick. If pregnant, this should contain hCG. (B) As the sample is absorbed into the stick it goes through free dye-labeled antibodies that recognize and stick to hCG. (C) An anchored set of antibodies stick to and capture hCG molecules (and the attached dye-labeled antibodies), creating the first line. In the "not pregnant" sample no hCG is attached to the dye-labeled antibodies, so they wash past this point and no line appears. (D) A second anchored set of antibodies captures the dye-labeled antibodies, providing a positive control to indicate that the test is working properly. |
