Manufacturer Narrative

Retention and returned products were tested with quality control cut-off standard (25 miu/ml hcg urine).All devices produced expected positive results at the read time and met specifications.No false negative results were observed.Review of manufacturing batch records for the reported lot did not uncover any abnormalities and quality control data met specifications.The reported complaint was not replicated during in-house testing as retention and returned products performed as expected.This test is designed for the qualitative detection of hcg in urine or serum to aid in the early detection of pregnancy.Per the package insert, very dilute urine specimens, as indicated by a low specific gravity, may not contain representative levels of hcg.If pregnancy is still suspected, a first morning urine specimen should be collected 24-48 hours later and tested.Based on the information available, there is no indication of a product deficiency and no corrective action is required.
