The PREGNANCY-SKREEN™ Human Chorionic Gonadotropin (hCG) Positive and Negative controls are prepared from human based urine. These hCG controls can be used to monitor the performance of qualitative immunochromatographic hCG detection devices.
Features and Benefits
- The positive control is spiked with hCG in a target range from 200-400 mIU/mL of urine matrix.
- The negative control is prepared from a urine pool that tested negative for hCG.
- The standard material used for spiking was obtained from human pregnancy urine lyophilized and found negative by ELISA to HIV-1, antibody for HCV and for HBSAG.
- The initial assay of the lyophilized material used for spiking was performed by radioimmunoassay.
- Subsequent testing of the control material is performed qualitatively to ascertain that positive controls tested positive and the negative controls tested negative for the claimed life of the product.
Procedure
- Allow controls to come to room temperature followed by gentle swirling or inversion before use. DO NOT SHAKE.
- Add an appropriate aliquot of Pregnancy-Skreen™ control urine as required by the hCG immunochromatographic device or screening
Limitations of Procedure
- This control is meant to be used to validate the performance of qualitative urine hCG methods that screen urine for hCG levels consistent with pregnancy. Consult test manufacturers’ instructions when using this product; changes in reagents, sample requirement, or methodology may effect test results.
