Based on an evaluation of the customer's results, this sample is a hook sample, however, siemens has requested the sample for further evaluation. The procedural notes high-dose hook effect section of the instructions for use (ifu) states the following: "patient samples with high total psa levels can cause a paradoxical decrease in the rlus (high-dose hook effect). In this assay, patient samples with total psa levels as high as 10,000 ng/ml (10,000 ug/l) will assay greater than 100 ng/ml (100 ug/l). " siemens issued urgent field corrective action cc 16-05. A. Ous and urgent medical device correction cc 16-05. A. Us on december 2015 informing the customer that the advia centaur systems prostate specific antigen (psa) assay kit lots ending in 263 and above are not meeting the current high-dose hook effect expectation in the instructions for use (ifu). Instructions on actions to be taken are provided in the customer communication. The sample was run neat on first presentation via aptio automation, then via the centralink trigger for all psa sample results >=40ug/l, the sample was repeated 1/5; then 1/10 then 1/50. After the last centralink automated dilution, the sample was routed by the trigger to the delivery sort lane on aptio for manual operator intervention. However, the operator simply placed the sample back into rerun in centralink without ordering a higher dilution as per laboratory protocol and the neat result was reported. The intended use section of the ifu states the following: "this in vitro diagnostic assay is intended to quantitatively measure prostate-specific antigen (psa) in human serum using the advia centaur and advia centaur xp systems. This assay is indicated for the measurement of serum psa in conjunction with digital rectal exam (dre) as an aid in the detection of prostate cancer in men aged 50 years and older. This assay is further indicated as an aid in the management (monitoring) of patients with prostate cancer. " the limitation section of the ifu states the following: " warning" "do not predict disease recurrence solely on serial psa values. " "do not interpret levels of psa as absolute evidence of the presence or the absence of malignant disease. Before treatment, patients with confirmed prostate carcinoma frequently have levels of psa within the range observed in healthy individuals. Elevated levels of psa can be observed in patients with nonmalignant diseases. Measurements of psa should always be used in conjunction with other diagnostic procedures, including information from the patient's clinical evaluation. "
