What should be done if a test result exceeds the highest standard in an ELISA test?

• A. Report as "greater than highest standard"
• B. Use a sample with lower dilution
• C. Calculate an average from previous results
• D. Increase the testing volume of the sample

Answer: (A)

In the context of an ELISA test, if the test result exceeds the highest standard, reporting the result as "greater than highest standard" is appropriate because it communicates to the clinician that the value is beyond the established measurement range for the assay. This designation provides clarity and indicates that the sample may warrant further investigation or different handling. Using a different dilution or sample volume (as other options suggest) could potentially yield a quantifiable result, but this approach may also introduce variability and does not provide the specific context that simply reporting the result above the highest standard does. Therefore, maintaining the integrity of the original test's standards while conveying the necessary information about the result's magnitude is critical in clinical practice. This allows healthcare professionals to make informed decisions based on the provided context of the test result.
