Event Description

The customer reported that one sample on the abbott ct/ng ii assay run had a "low-grade" positive result.The positive result was reported to the physician.The sample was re-tested, and the result was negative.The molecular application specialist (mas) reviewed the runs from abbottlink.The sample in question has good ic (internal control) amplification in both runs.The amplification curves and reference dye in the run looked as expected.The sample was a swab.In regards to the questioned results reported by the customer, the mas explained to the customer that due to nature of the specimen and behavior of the bacterial dna, the repeat test may not have picked up enough bacteria to have the ct detected.The customer will report the sample as "inconclusive", and they will request a repeat specimen.There was no impact on the patient's health due to the questioned results.Based on the mas review, this report is being processed as a false negative on the realtime ct/ng ii assay.
