Summary & Explanation

The PREGNANCY-SKREENTM hCG product line of controls is manufactured using a human based urine matrix that has been stabilized to insure that the product will be viable until the date of expiration. 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.
