Assay Validity

Assay validity refers to how accurately and reliably a laboratory test or analysis measures what it’s supposed to. It ensures that the test results are trustworthy, consistent, and reflect the true condition or substance being evaluated. Validity involves verifying that the assay produces precise results, correctly identifies the target, and is free from errors or interference. This is essential for making accurate decisions based on the data, whether in medical diagnostics, research, or product testing. Essentially, a valid assay provides confidence that the results are a true representation of the sample’s properties.
