A member asked:
Ana reflex was positive, with an rnp of 6.7 ai. the method used was immunoflouresence assay (also called ifa) instead of elisa. how do i interpret the result of 6.7 ai with this methodology? whats the range or scale for ai?
A doctor has provided 1 answer
With that method (IFA), result of 1 and higher is positive. High titer is common in MCTD but there are other overlap conditions so other serology tests need to be done for consideration. Take care.
