In a joint study of five laboratories the immunochemical tube test for pregnancy 'Roche', which uses the principle of the latex-agglutination inhibition test, was examined. A total of 1117 samples, complemented by a number of laboratory studies, proved that the test is specific, reproducible and low in interference with a sensitivity of 900-1000 U/l HCG. It is a simple test, the results can be easily read after 90 minutes. pH of the urine sample, protein, urea or calcium content, presence of oral contraceptives, detergents, disinfectants or organic solvents cause no or very little interference.
