Phenotyping algorithm for classifying Mi^a-positive MNS hybrid glycophorins using a panel of typing sera. ^# Phenotyping reagents used above cannot differentiate GP.Bun from GP.Kip RBCs. However, anti-Hop antiserum reacts positive with GP.Bun and negative with GP.Kip RBCs [14, 16, 38]. Anti-Hop antiserum is rare and is only available in specialised or reference testing laboratories. Molecular typing by DNA sequencing or MALDI-TOF MS is a more practical approach for distinguishing GP.Bun from GP.Kip hybrid glycophorins [33].
