THE ASSAY INSTRUCTIONS FOR USE DEFINES THE RANGE FROM 0.1 TO 0.34 KU/L AS \"VERY LOW\", WHERE THE CUSTOMER HAD INTERPRETED THESE RESULTS AS NEGATIVE. FOLLOWING THIS CLARIFICATION, THERE WERE STILL SOME OBSERVATIONS WHICH DEMONSTRATED INCONSISTENCY BETWEEN PANEL AND INDIVIDUAL-ALLERGEN RESULTS. SAMPLES WERE REQUESTED FOR TESTING, BUT WERE NOT AVAILABLE. PRODUCT STABILITY DATA FOR THE FOOD PANEL 5 ASSAY WERE REVIEWED, AND ALTHOUGH SOME DECREASE IN MEASUREMENTS WAS OBSERVED FOR THIS ASSAY OVER TIME, RESULTS DID NOT CHANGE FROM POSITIVE TO NEGATIVE; NO PRODUCT ISSUE WAS INDICATED.
