    (B)(4). CONCOMITANT MEDICAL DEVICE: ARCHITECT I2000SR ANALYZER, LIST # 3M74-02, SERIAL # (B)(4). RESULTS: CROSS CONTAMINATION WAS IDENTIFIED AS A POTENTIAL CAUSE. CONCLUSION: (B)(4). AN ADVERSE TREND IN US CUSTOMER COMPLAINTS FOR ARCHITECT HAVAB-IGM ASSAY (LIST NUMBER 6L21) REGARDING HIGHER THAN USUAL GRAYZONE/(B)(6) RESULTS RATE WAS DETECTED ON MARCH, 2009. THE INVESTIGATION REVEALED THE MOST PROBABLE CAUSE FOR THE INCREASE RATE OF (B)(6) RESULTS IS THE HAV ANTIGEN CODE 26286 WHICH HAS A REDUCED POTENCY THAT AFFECTS THE ARCHITECT HAVAB-IGM PERFORMANCE. (B)(4). AS A RESULT, THE SIGNAL TO NOISE RATIO IS SHIFTED SPECIALLY IN THE NEGATIVE SAMPLES LEAVING THE ASSAY PRONE FOR FALSE GRAYZONE/(B)(6) RESULTS AND INCREASES ARCH HAVAB-IGM ASSAY SUSCEPTIBILITY TO REAGENT CROSS CONTAMINATION AND TEST SYSTEM VARIABILITY. AS A PREVENTIVE MEASURE TO PROTECT THE INTEGRITY OF TEST RESULTS, CUSTOMERS WERE INSTRUCTED BY A PRODUCT INFORMATION LETTER TO FOLLOW AN ALTERNATIVE PROCESSING METHOD BY SEGREGATING ALL HAVAB-IGM SAMPLES.
