Negative: If a negative or a 1+
reaction is observed in the initial screening test against the Detection Latex,
the specimen is reported as negative.
Positive: If a 2+ or greater reaction against the Detection Latex is seen in the initial screening test, the specimen is titrated with the Detection Latex and Control Latex reagents. The titer is reported as the highest dilution showing a 2+ or greater reaction.
Positive with nonspecific interference: If the specimen titer with the Detection Latex is at least 4-fold higher than the non-specific interference, (Control Latex) titer, the test should be reported as "Positive with non-specific interference," and the specimen titers against the Detection Latex and Control Latex should be stated.
Invalid test due to nonspecific interference: If the specimen titer against the Detection Latex is not at least 4-fold higher than that with the Control Latex, the test should be reported as "Invalid due to nonspecific interference."
