NA: No Amplification; NT: Not test due to a shortage of sample volume. NALFA results are presented by identifying each positive sample. The signal (+) represents positive result; while the (-) represent negative results. Two independent assays were performed for the test of each clinical sample, with the results of the test listed below.
