INTRODUCTION

1. The HBsAg Test (Whole Blood/Serum/Plasma) is a rapid test to qualitatively detect the presence of HBsAg in whole blood, serum or plasma specimen. The test utilizes a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of HBsAg in whole blood, serum or plasma.

2. The HCV Test (Whole Blood/Serum/Plasma) is a rapid test to qualitatively detect the presence of antibody to HCV in a whole blood, serum or plasma specimen. The test utilizes colloid gold conjugate and recombinant HCV proteins to selectively detect antibody to HCV in whole blood, serum or plasma. The recombinant HCV proteins used in the test kit are encoded by the genes for both structural (nucleocapsid) and non-structural proteins.

3. The HIV 1.2 Test (Whole Blood/Serum/Plasma) is a rapid test to qualitatively detect the presence of antibody to HIV 1 and/or HIV 2 in whole blood, serum or plasma specimen. The test utilizes latex conjugate and multiple recombinant HIV proteins to selectively detect antibodies to the HIV 1.2 in whole blood, serum or plasma.

INTENDED USE

ACCU-TELL^® HBsAg/HCV/HIV Combo Cassette (Whole Blood/Serum/Plasma) is a rapid chromatographic immunoassay for the qualitative detection of Hepatitis B surface antigen(HBsAg),antibodies to Hepatitis C Virus, antibodies to HIV type 1 and type 2  in whole blood, serum or plasma.

TEST PROCEDURE

1. Bring the pouch to room temperature before opening it. Remove the test cassette from the sealed pouch and use it as soon as possible. Best results will be obtained if the assay is performed within one hour.

2. Place the test cassette on a clean and level surface.

For Serum or Plasma specimen:

Hold the dropper vertically and transfer 2 drops of serum or plasma (approximately 80μL) to the specimen well of the test cassette, then add 1 drops of buffer (approximately 40μL) and start the timer. Avoid trapping air bubbles in the specimen well. See the illustration below.

For Whole Blood specimen:

Hold the dropper vertically and transfer 3 drops of whole blood (approximately 120μL) to the specimen well of the test cassette, then add 2 drops of buffer (approximately 80μL) and start the timer. See the illustration below.

3. Wait for the colored line(s) to appear. The test result should be read at 10 minutes. Do not interpret the result after 20 minutes.

PERFORMANCE CHARACTERISTICS

Sensitivity and Specificity

HBsAg

The HBsAg Test (Whole Blood/Serum/Plasma) has been tested with a sensitivity panel ranging from 0 to 300 ng/ml. All 10 HBsAg subtypes produced positive results on The HBsAg Test (Whole Blood/Serum /Plasma). The test can detect 1 PEI ng/ml of HBsAg in Whole Blood, serum/plasma

Antibodies used for the HBsAg Test (Whole Blood/Serum/Plasma) were developed against whole Hepatitis B antigen isolated from Hepatitis B virus. Specificity of the HBsAg Test (Whole Blood/Serum/Plasma) was also tested with laboratory strains of Hepatitis A and Hepatitis C. They all yielded negative results.

Relative Sensitivity: >99.9% (97.5%CI*: 98.2%-100%)

Relative Specificity: 99.0% (95%CI*: 97.2%-99.8%)

Accuracy: 99.4% (95%CI*: 98.3%-99.9%)                      

*Confidence Intervals

HCV

The recombinant antigen used for the HCV Test (Whole Blood/Serum/Plasma) is encoded by genes for both structural (nucleocapsid) and non-structural proteins. The HCV Test (Whole Blood/Serum/Plasma) has passed a seroconversion panel and compared with a leading commercial HCV EIA test using clinical specimens.

The results show that the relative sensitivity of the HCV Test (Whole Blood/Serum/Plasma) is 99.1%, and the relative specificity is 99.5%.

Relative sensitivity: 99.1% (95%CI*: 94.9%~100.0%);  

Relative specificity: 99.5% (95%CI*: 98.6%~99.9%);

Accuracy: 99.4% (95%CI*: 98.6%~99.8%).                   

*Confidence Intervals

HIV 1.2

The HIV 1.2 Test (Whole Blood/Serum/Plasma) has correctly identified specimens of a seroconversion panel and has been compared to a leading commercial ELISA HIV test using clinical specimens. The results show that the relative sensitivity of the HIV 1.2 Test (Whole Blood/Serum/Plasma) is >99.99% and the relative specificity is 99.88%.

Relative sensitivity: >99.99% (97.5%CI*: 97.20%~100.0%); 

Relative specificity: 99.88% (95%CI*: 99.57%~99.99%);

Accuracy: 99.89% (95%CI*: 99.60%~99.99%).

Precision

Intra-Assay

Within-run precision has been determined by using 20 replicates of four different specimens containing different concentrations of HBsAg, HCV antibody and HIV 1.2 antibody. The negative, positive values were correctly identified 100% of the time.

Inter-Assay

Between-run precision has been determined by 20 independent assays on the same four different specimens containing different concentrations of HBsAg, HCV antibody and HIV 1.2 antibody. Three different lots of ACCU-TELL^® HBsAg/HCV/HIV Combo Cassette (Whole Blood/Serum/Plasma) have been tested over a 3-month period using above negative and positive specimens. The specimens were correctly identified 100% of the time.

Cross-reactivity

The HBsAg Test (Whole Blood/Serum/Plasma) has been tested by HAMA, Rheumatoid factor (RF), HAV, Syphilis, HIV, H. Pylori, MONO, CMV, Rubella, HCV, HEV and TOXO positive specimens. The results showed no cross-reactivity

The HCV Test (Whole Blood/Serum/Plasma) has been tested by HAMA, RF, HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, Syphilis,HIV, H. Pylori, MONO, CMV, Rubella and TOXO positive specimens. The results showed no cross-reactivity.

The HIV 1.2 Test (Whole Blood/Serum/Plasma) has been tested by HAMA, RF, HBsAg, HBsAb, HBeAg, HBeAb, HBcAb, HCV,Syphilis, H. Pylori, MONO, CMV, Rubella and TOXO positive specimens. The results showed no cross-reactivity.

Interfering Substances

The following potentially interfering substances were added to HBsAg, HCV antibody and HIV 1.2 antibody negative and positive specimens.

None of the substances at the concentration tested interfered in the assay.

LIMITATIONS

1. This test is for in vitro diagnostic use only.

2. This test has been developed for testing Whole Blood/Serum /Plasma specimens only. The performance of the test using other specimens has not been substantiated.

3. This test is a qualitative screening assay. It is not designed to determine the quantitative concentration of HBsAg, HCV antibody or HIV 1.2 antibody.

4. The HBsAg Test cannot detect less than 1 PEI ng/ml of HBsAg in specimens.

5. As with all diagnostic tests, all results must be considered with other clinical information available to the physician.

6. If the test result is negative and clinical symptoms persist, additional follow-up testing using other clinical methods is recommended. A negative result at any time does not preclude the possibility of HBsAg and/or Hepatitis C Virus and/or HIV1.2.
