To perform latex agglutination, by what should the specimens be treated before testing? Correct Answer EDTA

To perform latex agglutination, it is recommended that all specimens should be treated by boiling with EDTA (i.e., ethylenediaminetetraacetic acid). This is because, some constituents of body fluid like Rh factor have found to cause false-positive reactions in latex agglutination. Therefore, to avoid this risk, EDTA wash is preferable as it is a chelating agent so that it will deactivate the specimen from causing any side effect.

Six students of a school – Radha, Raj, Rahul, Mira, Aarav and Arijit are selected from different classes – 7th, 8th, 9th, 10th, 11th and 12th standards (not necessarily in the same order) to perform individually in the school annual function. Their order of performances is decided as per their classes. The one who is in 12th class will perform first, then after that 11th class student will perform and so on.
