Test Principle:

The device employs lateral flow immunoassay technology for detection of human chorionic gonadotropin (hCG) in urine and or serum. Monoclonal for hCG Combo) goat anti-hCG antibodies are pre-striped in the nitrocellulose membrane on the test region (T line) and goat antimouse antibodies on the control region (C line). During testing, the urine/serum specimen reacts with the conjugate pad (It contains colloidal gold particles conjugated with monoclonal anti-hCG antibody specific to the beta subunit of hCG) located just beneath the sample pad and above the membrane of the test strip. The specimen migrates upward on the membrane by capillary action to react with the antibodies on the membrane. If the hCG concentration in at or above the designated detection limit, a red colored line at the test region will be present indicating a positive result, while its absence indicates a negative result. The control line (C line) serves as an internal quality control. The control line should always appear, regardless of the hCG concentration of the test specimen, and the C line is an indicator that sufficient sample volume has been added to the test device and the sample has correctly migrated up the test strip.

Table 2-b. Chemtrue® hCG Combo (Serum) Test:

CONCLUSION: The results confirmed the claimed cutoff (sensitivity/detection limit) levels for the Chemtrue " hCG Tests in Dipstick/Cassette configurations, as well as the hCG Combo Test. Also the results demonstrated that the functional performance is consistent between lot-to-lot of all the device formats/ configurations.

Linearity/assav reportable range: Linearity is not applicable since this is a qualitative test.

Traceability, Stability, Expected values (controls, calibrators, or methods): Chemtrue® hCG Pregnancy Tests are calibrated against reference material traceable to WHO International Standard 5th edition.

A shelf-life stability test of the devices was performed in real-time and accelerated testing. The results showed that the devices were stable for 24 months when stored at 25°C±2°C in the sealed foil pouch. Protocol and acceptance criteria were reviewed and are acceptable.

The sensitivity was evaluated in conjunction with the Cut-off characteristics and precision testing. Refer to the precision data in section 2 below. The detection limit was demonstrated to be 20 mIU/mL for urine test and 25 mIU/mL for hCG Combo test.

  1. Reproducibility (Precision) Study: The study was conducted in three (3) POL sites by a total of nine (9) operators and three (3) operators for each site with three (3) lots of each proposed device formats over three (3) non-consecutive days. The blind coded controls were used with hCG spiked at the concentrations of 0, 10, 15, 20, 25, 30 and 35 mIU/mL in urine; 0, 15, 20, 25, 30 and 35 mIU/mL in serum (Used for hCG Combo Test). The controls were calibrated against WHO 50" IS (07/364) and the values were confirmed with a FDA cleared Abbott chemiluminescent quantitative immunoassay, i2000 (Abbott Park, Illinois, 60064-3500, U.S.A). Every device was tested and interpreted by the same operator at 5 minutes as the read time, per package insert request. The reproducibility between the sites is summarized in tables below:

Table 7. Comparison among two device formats for Chemtrue® hCG urine Tests

CONCLUSION: The results demonstrate a consistent functional performance of the Chemtrue® hCG Tests between the sites and device formats/configurations.

Reproducibility study data among the operators: The results demonstrate that the performance of each Chemtrue® hCG Test format was similar between nine (9) operators across all three (3) study sites.

  1. Method Comparison Study Data Summary: Chemtrue® hCG Pregnancy Tests were compared with the Predicate kits. A total of 300 clinical urine samples were blind coded and tested with each device format by nine (9) operators from three (3) POL sites (three operators in each site) in Shanghai China. One hundred-fifty (150) hCG negative urine samples (collected from women of childbearing age, including peri-menopausal) and 150 hCG positive samples that represented women who were suspected to be pregnant within the first 30 days of pregnancy/the first trimester of pregnancy in the early pregnancy and late pregnancy. 50 hCG negative serum samples and 50 hCG positive serum samples that are representative for the populations of the intended use were used for the study. The hCG positive serum samples were quantitatively confirmed by Abbott i2000 instrument. Each specimen was evenly split into three aliquots. Each site tested 100 samples with a unique set of blind codes for each device formation. The results are summarized in tables below: Table 8.

CONCLUSION: The results demonstrate that hCGBcf up to 1,000,000 pmol/mL does not interfere with the Chemtrue® hCG Tests.

The effect of specific gravity (SG) and pH were evaluated by testing duplicates at each sample level of hCG negative and 20 mIU/mL (25 mIU/mL for Combo Test) urine controls with pH 2.0 to 9.0, and SG of 1.003 to 1.030. No interference was observed for pH value 2.0 to 9.0 and SG values from 1.003 to 1.030. However, labeling states that low concentrations of hCG may not be detected in very dilute urine and, if pregnancy is suspected, testing should be repeated after 48 hours. The detailed data is enclosed in ATTACHMENT D, page 74 of the submission.

Flex studies were performed and include read time and sample volume verifications. The results support the claims in the package inserts. The study reports are presented in ATTACHMENT H, pages H9 to H25 of the submission.
