Would a high rate of false positives decrease the sensitivity or specificity of a serological test?

A high rate of false positives decreases the specificity of a serological test, as specificity measures the test's ability to correctly identify true negatives. In contrast, sensitivity, which assesses the test’s ability to correctly identify true positives, remains unchanged by the rate of false positives. Therefore, while increased false positives affect specificity, they do not directly impact sensitivity.
