Reason For Recall Siemens Healthcare Diagnostics received complaints of Chemistry Wash causing QC and patient sample result shifts on CTN1, LTN1, FT4, TSH, PBNP and LPBN when using Chemistry Wash lots RD23031, RD23111, RD23241, RD23311, RD23391, and RD23461. These lots shipped between 12/12/2012 and 3/22/2013. Internal investigation has confirmed shifts can be encountered in two scenarios: 1 - When an affected lot of Chemistry Wash is placed on the instrument following an unaffected lot, a negative bias will be seen on CTN1, LTN1, TSH, PBNP and LPBN. A positive bias will be seen on FT4; 2 - If any of these assays are calibrated using an affected lot of Chemistry Wash, QC should return within range; but when a subsequent unaffected Chemistry Wash lot is placed into use, a positive bias will be seen on CTN1, LTN1, TSH, PBNP and LPBN. A negative bias will be seen on FT4.
