MAUDE data represents reports of adverse events involving medical devices. This maude entry was filed from a 01,05,06 report with the FDA on 2014-01-16 for IMMULITE 2000 ANDROSTENDIONE L2KA0 manufactured by Siemens Healthcare Diagnostics Inc..
[19322876]
Siemens has investigated the incidence of over recovery of patient samples and quality controls on the immulite/immulite1000 androstenedione assay lot number 409 and above, and immulite 2000/immulite 2000 xpi androstenedione assay lot number 314 and above. Siemens has confirmed that these lots are linear up to a concentration of 5. 5 ng/ml, instead of the 10 ng/ml as stated in the instructions for use (ifu). Quality control materials at concentrations between 5. 5 ng/ml and 10 ng/ml will detect this issue. An urgent medical device correction (umdc) 2013-12-19 was sent to us customers and an urgent field safety notice (ufsn) 4008 was sent to ous customers in december of 2013. The umdc and ufsn state that customers are requested to use quality control materials with at least two levels having concentrations less than 5. 5 ng/ml, and that patient values >5. 5 ng/ml should be verified using an alternate method.

The customer observed high bias on the level 2 and level 3 quality controls (qc) and low bias on the level 1 qc when using kit lot 318 of the immulite 2000 androstenedione assay. The customer ran the qc on an immulite 2000 instrument. There are no known reports of adverse health consequences due to the high bias on the level 2 and level 3 qc and low bias on the level 1 qc when using kit lot 318 of the immulite 2000 androstenedione assay.

The original mdr 2432235-2014-00061 was filed on january 16, 2014. Additional information (5/27/14): the over recovery and loss of linearity of the immulite systems androstenedione assay has been identified to be variability of a critical raw material (variation in the activity of rma160 alkaline phosphatase (unlabeled/low activity alkaline phosphatase, cold ap) in the reagent wedge). In addition, siemens healthcare sent out a customer bulletin 2014-05 in may 2014, announcing the restoration of the linearity of the androstenedione assay on the immulite 2000/immulite 2000 xpi to 10 ng/ml (35 nml/l), beginning with kit lot 331.
