Comparative study of sensitivity and specificity of beta monoclonal agglutination inhibition and sandwich immunometric assay tests in the diagnosis of pregnancy

Urine of 30 pregnant females was tested for gravidex test. Both concentration and agglutination inhibition [Beta monoclonal] tests were performed on the same urine specimens. Results showed that the sensitivity and specificity of the concentration [colour] test was much higher than that of the B monoclonal test
