Method and test kit suitable for determination of the level of a diagnostically relevant isoenzyme in a biological fluid sample. This method and test kit are based upon the determination of residual enzyme activity of a biological fluid sample subsequent to inhibition of the diagnostically relevant isoenzyme within the sample. Such neutralization/immunoinhibition of the enzyme is accomplished with a relatively impure, low avidity anti-serum which is specific for the isoenzyme. This assay is unique in that the anti-serum which is employed in the neutralization/immunoinhibition of the isoenzyme is only effective in the neutralization/immunoinhibition of from at least about 50% to up to about …
