    AN INVESTIGATION WAS INITIATED IN RESPONSE TO A CUSTOMER COMPLAINT OF OBTAINING FALSELY UNDERESTIMATED RESULTS FOR A PATIENT SAMPLE IN ASSOCIATION WITH VIDAS® TSH TEST KIT (REF 30400, LOT 1007708000). TWO SAMPLES WERE SUBMITTED BY THE CUSTOMER FOR THE INVESTIGATION. THE COMPLAINT LABORATORY PERFORMED TESTING ON INTERNAL SAMPLES AS WELL AS THE CUSTOMER'S SAMPLES WITH MULTIPLE LOTS INCLUDING THE CUSTOMER'S LOT. ALL TEST RESULTS FROM INTERNAL SAMPLES WERE WITHIN SPECIFICATION AND DID NOT INDICATE AN ISSUE WITH THE PRODUCT. TESTING THE CUSTOMER'S SAMPLES REPRODUCED THE CUSTOMER'S ISSUE FOR ONE SAMPLE, BUT NOT FOR THE SECOND SAMPLE. THE INVESTIGATION CONCLUDED THAT THE CAUSE FOR THE FALSELY UNDERESTIMATED RESULTS WAS NOT RELATED TO A SPECIFIC LOT OF PRODUCT, BUT RATHER AN INTERFERENCE PRESENT IN THE PATIENT SAMPLE. NO FURTHER INVESTIGATION INTO THE SOURCE OF THE INTERFERENCE COULD BE COMPLETED AS THERE WAS NOT ENOUGH SAMPLE FOR ADDITIONAL TESTING.
