Please retain this letter with your laboratory records and forward this letter to those who may have received this product. The firm reports that a removal at this time is not necessary because: "Siemens does not intend to remove the product as based on available data, it is estimated the occurrence is <1%. Siemens recommends that the laboratories follow their internal procedures if interference is suspected. A Follow up Urgent Medical Device Correction dated 1/13/20 was sent to customers. Actions to be Taken by the Customer Note: Interference will not be detected by quality control and the presence of the interference may not be readily identifiable. Follow your established internal procedures to determine if additional testing is needed to identify samples with suspected interference and to determine if the patient sample result is accurate. A potential approach to identify interference is to dilute the sample. In-house studies have shown that a 1:5 dilution of the sample is effective in diluting out the potential interferant. Please note that for samples with an undiluted result of d 1 ng/mL, greater variability could potentially be observed after dilution due to assay precision in this region. Instructions Please review this letter with your Medical Director. Complete and return
