What does high specificity in antibodies imply?

High specificity in antibodies indicates that the antibodies are very selective for their target antigens, which leads to a low rate of false positives. When an antibody has high specificity, it means that it binds predominantly to the intended antigen and not to other closely related proteins or molecules in the sample. This characteristic is crucial for accurate diagnostic tests, ensuring that a positive result is truly indicative of the presence of the target antigen rather than a false signal caused by non-specific binding to other substances present in the sample.

Thus, in clinical and laboratory settings, utilizing antibodies with high specificity can significantly enhance the reliability of test results, which is particularly important in diagnosing conditions based on the presence of specific pathogens, hormones, or biomarkers in the body.
