title: [A new immunochemical tube test for pregnancy using the latex-agglutination inhibition reaction. II. Clinical results (author's transl)].
abstract: In a multi-centre study 1117 morning urine samples were tested using the new immunochemical pregnancy tube test (Roche), based on the principle of indirect latex-agglutination inhibition. The test proved to be both qualitatively and semi-guantitatively suitable for demonstration of HCG in urine. There was only one false-negative result among 320 pregnancy tests (after 50th postmenstrual day). In 94 early pregnancies (test done before the 50th day) there were only two false-negative results. No false-positive result were seen. In the prognosis of threatened abortion, diagnosis of incomplete abortion, hydatid cyst, or chorionepithelioma the semiquantitative performance of the test was clinically useful and especially suitable because the result of the agglutination-inhibition reaction is unequivocal.
