[811493]
A customer observed falsely reactive ahav igm results from a single pt tested on the vitros eci analyzer. The results did not agree with results generated on a competitive method. Quality control results were within acceptable ranges. Erroneous anti-hav igm results may lead to confusion in the diagnosis and treatment of acute hepatitis. The reactive vitros result was reported, however, there was no allegation of harm as a result of this event. Note: there are two consecutively numbered form 3500a being filed for this event. The falsely reactive ahav igm results were obtained on two different ahav igm reagent lots (lot 1110, mdr # 9680658-2008-00091 and lot 1160, mdr #9680658-2008-00092).

Investigation into this event found that the reactive results occurred with two different vitros ahav igm reagent lots and on two different vitros eci systems. The root cause of the reactive results could not be determined, however, the pt's condition and other test results indicate that the true classification of the sample is ahav igm negative. While the cause is unk, it is not due to analyzer, which performed acceptably, but might be due to a sample interferent.
