What does the acronym MFI stand for?

• A. Mechanical fixation immunoassay
• B. Molecular fusion immunoassay
• C. Maximum factor immunoassay
• D. Multiplex fluorescent immunoassay

Answer: (D)

Multiplex fluorescent immunoassay is a method that uses fluorescent signals to measure several targets at once in a single sample. In this approach, antibodies specific to each analyte are configured so that each target can be detected in its own fluorescent channel or on distinct fluorescent beads, allowing simultaneous capture and readout of multiple substances. This enables high-throughput testing, saves sample volume and reagents, and provides the ability to compare multiple analytes under the same conditions in one run. The fluorescence readout provides quantitative data for each target, typically with a broad dynamic range and good sensitivity. Other terms like mechanical fixation immunoassay, molecular fusion immunoassay, or maximum factor immunoassay don’t describe a standard field-validated technique for concurrent detection of several analytes using fluorescence, so they aren’t correct in common laboratory practice.
