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 2000/IMMULITE 2000 XPI 3G ALLERGEN SPECIFIC IGE L2KUN manufactured by Siemens Healthcare Diagnostics Products, Limited.
[95617029]
Siemens healthcare diagnostics has confirmed that biotin interferes with the 3g allergen assay on immulite 2000/immulite 2000 xpi platform. At biotin concentrations of >5 ng/ml a negative bias that exceeds 10% has been observed on the immulite 2000/immulite 2000 xpi 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.

Siemens technical operations internal investigation has identified that discordant falsely low results were obtained on two investigational samples on an immulite 2000/ immulite 2000 xpi instrument when using the 3g allergen specific ige assay. Five specific allergens were used for the testing - olive specific allergen, cat dander, latex allergen, wheat allergen, and chironomus spp allergen. The two investigational samples were spiked with biotin at multiple concentrations, for each specific allergen and run for investigational purposes on an immulite 2000/immulite 2000 xpi instrument. A greater than one class change (falsely low) in result was observed at biotin concentrations of 250 ng/ml with olive allergen, 100 ng with cat dander allergen, 75 ng/ml with latex allergen, 250 ng/ml with wheat allergen and 75 ng/ml of chironomus spp allergen respectively compared to results of the two samples without biotin. There were no patient samples impacted as this was for investigational purposes only.
