`Wellcozyme HIV 1+2' enzyme immunoassay kits, one of two, used to test for antibodies to HIV in blood samples, with 480 wells, without chemicals, from Murex Diagnostics Ltd, England, 1993

This kit allowed the user to test for HIV 1+2 antibodies in blood samples to prevent the transmission of the disease through blood transfusions. HIV 1 is the most common type of infection and also leads to AIDS. This kit allowed the user to test for antibodies in a safe, easy and effective way. Urine, saliva and dried blood spots could also be tested in place of a regular blood sample – especially useful if the person being tested had difficulty in giving blood. The test did not require highly trained personnel or a laboratory and so could be used by anyone with a small amount of training, anywhere.
