    Additional Manufacturer Narrative · 1

    A CUSTOMER FROM THE UNITED STATES REPORTED A MISIDENTIFICATION OF CANDIDA GUILLIERMONDII CAP SURVEY SAMPLE (F1-A 2018) IN ASSOCIATION WITH THE VITEK® 2 YST TEST KIT (LOT #2430541203). AN INTERNAL BIOMÉRIEUX INVESTIGATION WAS PERFORMED. THE CUSTOMER OBTAINED AN INCORRECT IDENTIFICATION WHEN TESTING CAP SURVEY ISOLATE F1-02 2018 ON VITEK 2 YST CARDS. THE EXPECTED IDENTIFICATION WAS CANDIDA GUILLIERMONDII; HOWEVER, THE CUSTOMER OBTAINED AN EXCELLENT IDENTIFICATION OF CANDIDA FAMATA. ON A SECOND RUN, THE CUSTOMER OBTAINED A LOW DISCRIMINATION CALL OF C. FAMATA/C. GUILLIERMONDII. THEREFORE, THE CUSTOMER REPORTED C. FAMATA AS THEIR FINAL ANSWER. IT SHOULD BE NOTED THAT BOTH C. GUILLIERMONDII AND C. FAMATA/C. GUILLIERMONDII WERE ACCEPTABLE ANSWERS; HOWEVER, C. FAMATA ALONE WAS NOT. BOTH THE CUSTOMER SUBMITTED STRAIN AND THE INTERNAL CAP SURVEY STRAIN WERE SUBBED AND TESTED ON THE CUSTOMER LOT AND A RANDOM LOT OF VITEK 2 YST CARDS, IN DUPLICATE. API® 20C AUX AND VITEK® MS WERE ALSO PERFORMED. CUSTOMER SUBMITTED STRAIN (911598): ON ALL FOUR (4) CARDS TESTED, A LOW DISCRIMINATION CALL OF C. FAMATA/C. GUILLIERMONDII WAS OBTAINED. API 20C AUX GAVE A VERY GOOD ID (99.7%) OF C. GUILLIERMONDII AND VITEK MS GAVE AN IDENTIFICATION OF C. GUILLIERMONDII, WITH A 99.9% CONFIDENCE LEVEL. SINCE C. GUILLIERMONDII WAS PART OF THE LOW DISCRIMINATION CALL ON ALL CARDS TESTED, CARDS ARE PERFORMING AS EXPECTED FOR THIS ORGANISM. INTERNAL SURVEY STRAIN (911599): A LOW DISCRIMINATION CALL OF C. FAMATA/C. GUILLIERMONDII WAS OBTAINED ON ONE (1) CARD FROM THE CUSTOMER LOT AND ONE (1) CARD FROM THE RANDOM LOT. AN EXCELLENT ID OF C. FAMATA WAS OBTAINED ON ONE (1) CARD FROM THE CUSTOMER LOT AND ONE (1) CARD FROM THE RANDOM LOT. API 20C AUX GAVE A VERY GOOD ID (99.7%) OF C. GUILLIERMONDII AND VITEK MS GAVE AN IDENTIFICATION OF C. GUILLIERMONDII, WITH A 99.9% CONFIDENCE LEVEL. A COMPARISON OF CARD REACTION RESULTS AGAINST EXPECTED REACTION RESULTS FOR C. GUILLIERMONDII REVEALED ONE (1) ATYPICAL NEGATIVE REACTION (DGATA) THAT LED TO THE INCORRECT CALL. CONCLUSION- ATYPICAL STRAIN.
