H2 - if follow-up, what type?: updated to additional information.H6 - adverse event problem: codes updated as the investigation was completed.H10 - additional mfg narrative: updated as the investigation was completed.Investigation conclusion: retained devices from the reported lot number were tested with hcg-negative clinical urine, hcg-negative clinical serum, 20 miu/ml hcg urine cut-off, and 10 miu/ml hcg serum cut-off samples.The results of the negative urine samples were read at 3 and 4 minutes and the results of the negative serum samples were read at 5 and 6 minutes.All devices yielded valid negative results.The results of the cut-off hcg urine samples were read at 3 minutes and the results of the cut off serum samples were read at 5 minutes.All devices tested with cut-off samples yielded positive results.No erratic or results issues were observed during in-house testing.The case details were reviewed along with the complaint history for the reported issue and no indications of a systemic issue were identified.Manufacturing batch record review did not uncover any relevant non-conformances and found that the lot met quality control specifications.Review of the risk management report for this product found that the reported issue is within the risk profile for this device; no new hazard has been identified.A root cause could not be determined from the available information as the reported issue was not replicated during testing of retention product.Complaints are tracked and trended on a monthly basis.Please note: a first morning urine specimen is preferred since it generally contains the highest concentration of hcg, however, urine specimens collected at any time of the day may be used.As a result, the concentration of hcg collected later in the day could be lower.Therefore this could lead to discrepancies between serum and urine.H3 other text : although requested, device return not anticipated.
