As method of determining an analyte is described, where a medium suspected of containing an analyte is drawn into a capillary tube by capillary action, such that if the analyte is present, it becomes immobilized in the tube. This medium is expelled from the tube and, optionally, one or more additional reagents are similarly drawn up and expelled. When the last fluid is expelled from the tube, a pendulous drop is caused to form at the opening of the capillary tube and is examined for the presence or intensity of the signal, which is related to the presence or amount of analyte in the medium. |
