Summary of Performance Studies (study type, sample size, AUC, MRMC, standalone performance, key results)
1. Analytical Performance
- Precision/Sensitivity: Precision and Sensitivity study was performed by spiking the negative urine with hCG to obtain at concentrations at 0, 12.5, 18.75, 25, 37.5, 50 and 100mIU/mL. Thirty replicates were tested with each spiked urine sample. Three (3) different Lots for each test format were used to perform the testing. The results demonstrated that the analytical sensitivity of the INNOVITA HCG Pregnancy Rapid test is 25mIU/mL.
- Linearity and Reportable Range: This device provides qualitative results only.
- Traceability and Stability: INNOVITA HCG Pregnancy Rapid Test Pregnancy Rapid Test is calibrated against reference material traceable to WHO International Standard 5th edition. Stressed Stability Study and Real-Time Shelf-Life Study were conducted to monitor the integrity of the INNOVITA HCG Pregnancy Rapid Test. Testing results demonstrate that the shelf-life of the test is 3 years when stored at 4°C-30°C in a sealed foil pouch.
- Detection Limit: See precision section above (F.1.a)
- Analytical Specificity:
- Cross Reactivity: To evaluate the cross reactivity with similar hormone compounds, negative urine samples and different levels of HCG negative and HCG positive (25mIU/ml and 100mIU/ml) urine were spiked with different levels of hormone LH (250, 500 and 750mIU/ml), FSH (500, 750 and 1000mIU/ml) and TSH (500, 750 and 1000μIU/ml). Five devices from each format were tested with each spiked urine samples. The results summarized below demonstrated no cross-reactivity at 500mIU/ml LH, 1000mIU/ml FSH or 1000μIU/ml TSH.

D. Test Principle
When hCG containing urine, sample is applied onto the sample pad, it is diffused through the conjugate pad where hCG forms an antigen-antibody complex with colloidal gold-labeled antibodies. Under the lateral flow action, the complex migrates forward along the test. When passing the T line in the testing zone, the complex is captured and immobilized by pre-coated antiahCG antibodies on the T line and form a pink color line. The free Au-anti-BhCG continues to migrate in the testing zone. When passing the C line, the Au-anti-BhCG mouse antibodies is captured and immobilized by goat -anti-mouse IgG antibodies on the C line and form a pink color.
When there is no hCG in the sample, only a pink to purple line appear in the C line, indicating the specimen is negative. The pink line in the control region is to show that the applied specimen is adequate and migrates well. It also serves as an internal control standard for the reagent.

To evaluate the effect of urine specific gravity (S.G.) on the INNOVITA HCG Pregnancy Rapid test, negative urine samples and positive urine samples with different specific gravities (1.000 - 1.010, 1.011 - 1.020 and 1.021 - 1.030) were collected. hCG was spiked into these urine samples to generate positive urine sample containing 25mIU/mL hCG. Five devices from each format were tested with each urine sample. Results demonstrated that test results were not affected by urine specific gravity between 1.003 and 1.030.

hCG ß-core Fragment V.
Presence of hCG ß-core fragment in urine were evaluated their effect on the performance of INNOVITA HCG Pregnancy Rapid test. Negative urine samples and hCG positive (25mIU/ml) urine samples were spiked with hCG-ß core fragment at the concentrations of 0.5umol/L and 1umol/L. Three devices from each format were tested with each spiked urine samples. The results demonstrated that no interference was observed for hCG-ß core fragment concentrations up to l umol/L equivalent to 1000, 000 pmol/L.

High Dose Hook Effect vi.
High concentrations of hCG in urine were evaluated for their effect on the performance of INNOVITA HCG Pregnancy Rapid test. Negative urine samples were spiked with hCG standard to make samples that contain hCG concentration at 25mIU/mL, 100mIU/mL, 11U/mL, 10IU/mL, 100IU/mL, 150IU/mL, 500IU/mL, 1000IU/mL and 2000IU/mlL. Three devices from each format were tested with each spiked urine samples. The results demonstrated that no hook effect was observed for hCG concentrations up to 2000IU/mL.

2. Comparison Study
- a. Method Comparison with Predicate
Method Comparison was performed at three sites where 300 fresh urine samples were collected from females with ages ranging from 18 to 49. For each of urine sample, HCP perform one test using the INNOVITA HCG Pregnancy Rapid Test and one test using the One Step Pregnancy Test (predicate). Total 5 HCP were involved in this study. Three lots of devices were used for comparison study. Tests were carried out with the matched test format. Test results obtained are summarized in the table below:
