Manufacturer Narrative

Investigation conclusion: retention products were tested with hcg quality control cut-off standard (25 miu/ml) and high level hcg clinical urine (212.6 iu/ml, 215.2 i u/ml, 203.5 iu/ml).All devices showed positive results at read time and met quality control release specifications.No false negative results were obtained during in-house testing.Manufacturing batch record review did not uncover any abnormalities.Case details do not indicate if the urine sample was a first morning catch.Per the package insert, very dilute urine may not contain representative levels of hcg.This test provides a presumptive diagnosis for pregnancy.A confirmed pregnancy diagnosis should only be made by a physician after all clinical and laboratory findings have been evaluated.Based on the information available, there is no indication of a product deficiency and no corrective action is required.
