Which of the following would be considered a disadvantage of ELISA in some settings?

• A. High sensitivity
• B. Titer detection
• C. Rapid results
• D. Specificity

Answer: (B)

ELISA can quantify antibody levels and provide titer information, which is useful for detailed immune profiling. But determining exact titers requires running serial dilutions and constructing standard curves, adding extra steps, time, and potential variability between runs. In settings that prioritize speed, simplicity, or screening over precise measurement, this titer-detection requirement can feel like a drawback. The other attributes—high sensitivity, rapid results, and specificity—remain clear advantages that ELISA offers.
