MAUDE data represents reports of adverse events involving medical devices. This maude entry was filed from a foreign,study report with the FDA on 2017-12-14 for IMMULITE/IMMULITE 1000 OM-MA L2KOP manufactured by Siemens Healthcare Diagnostics Products, Limited.
[95801203]
Siemens healthcare diagnostics has confirmed that biotin interferes with the ca-125 (om-ma) assay on the immulite/immulite 1000 platform. At biotin concentrations of >2 ng/ml a positive bias that exceeds 10% has been observed on immulite/immulite platforms. This issue affects previously manufactured, in-date, and future lots. The immulite platform instructions for use (ifu's) currently do not have biotin listed as a potential interferent. An urgent field safety notice (ufsn) imc 18-02. A. Ous was sent out to ous customers and an urgent medical device recall (umdr) imc18-02. A. Us was sent to us customers on december 13, 2017. The ufsn and umdr informs the customers of biotin interference on all affected immulite assays. Siemens will update all ifu's with the appropriate biotin information.

[95801204]
Siemens technical operations internal investigation has identified that discordant falsely high results were obtained on two investigational samples on an immulite/ immulite 1000 instrument when using the om-ma (ca 125) assay. Two investigational samples were spiked with biotin at multiple concentrations, and run for investigational purposes on an immulite/ immulite 1000 instrument. The results of the two samples spiked with 75 ng/ml of biotin were falsely high with a bias of +45% and +38% respectively compared to results of the two samples without biotin. There were no patient samples impacted as this was for investigational purposes only.
