PERFORMANCE CHARACTERISTICS
Accuracy
A multi-center clinical evaluation was conducted comparing the results obtained using the hCG
One Step Pregnancy Combo Test Device (Urine/Serum) to another commercially available urine membrane hCG test. The study included 150 urine specimens, and both assays identified 72
negative and 78 positive results. The results demonstrated >99% overall accuracy of the hCG One Step Pregnancy Combo Test Device (Urine/Serum) when compared to the other urine membrane hCG test.
Sensiticity and Specifity
The hCG One Step Pregnancy Combo Test Device (Urine/Serum) detects hCG at a concentration of 25mIU/mL or greater. The test has been standardized to the W.H.O. International Standard. The addition of LH (500mIU/mL), FSH (1,000mIU/mL), and TSH (1,000µIU/mL) to negative (0mIU/mL hCG) and positive (25mIU/mL hCG) specimens showed no cross-reactivity.
Interfering Substances
The following potentially interfering substances were added to hCG negative and positive specimens.
Acetaminophen 20 mg/dL Caffeine 20 mg/dL
Acetylsalicylic Acid 20 mg/dL Gentisic Acid 20 mg/dL
Ascorbic Acid 20 mg/dL Glucose 2 g/dL
