    SERVICE WAS NOT DISPATCHED AS THE CUSTOMER DID NOT QUESTION SYSTEM PERFORMANCE. SAMPLES WERE COLLECTED IN THE LITHIUM HEPARIN TUBES. NO SYSTEM CHECK DATA WAS SUPPLIED BY THE CUSTOMER. CUSTOMER PRODUCT LINE SUPPORT (CPLS) LABORATORY TESTING CONFIRMED INTERFERING SUBSTANCES IN THE PATIENT BLOOD. HETEROPHILE INTERFERENCE IS THE ROOT CAUSE FOR THE DISCORDANT RESULTS. PRODUCT LABELING: FOR ASSAYS EMPLOYING MOUSE ANTIBODIES, THE POSSIBILITY EXISTS FOR INTERFERENCE BY HUMAN ANTI-MOUSE ANTIBODIES (HAMA) IN THE SAMPLE. HUMAN ANTI-MOUSE ANTIBODIES MAY BE PRESENT IN SAMPLES FROM PATIENTS WHO HAVE RECEIVED IMMUNOTHERAPY OR DIAGNOSTIC PROCEDURES UTILIZING MONOCLONAL ANTIBODIES OR IN INDIVIDUALS WHO HAVE BEEN REGULARLY EXPOSED TO ANIMALS. ADDITIONALLY, OTHER HETEROPHILE ANTIBODIES, SUCH AS HUMAN ANTI-GOAT ANTIBODIES, MAY BE PRESENT IN PATIENT SAMPLES.

THUS TROPONIN I (ACCUTNI) RESULTS SHOULD BE INTERPRETED IN LIGHT OF THE TOTAL CLINICAL PRESENTATION OF THE PATIENT, INCLUDING: SYMPTOMS, CLINICAL HISTORY, CLINICAL EXAMINATION, ELECTROCARDIOGRAM (ECG), DATA FROM ADDITIONAL TESTS, AND OTHER APPROPRIATE INFORMATION. MEDICAL DECISIONS SHOULD NOT BE BASED ON A SINGLE ACCUTNI DETERMINATION AT ONE TIME POINT.
