INTRODUCTION
1. The HBsAg Rapid 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 Rapid Test (Whole Blood/Serum/Plasma) is a rapid test to qualitatively detect the presence of antibody to HCV in 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 Rapid 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.
4. The Syphilis Rapid Test (Whole Blood/Serum/Plasma) utilizes a double antigen combination of a Syphilis antigen coated particle and Syphilis antigen immobilized on membrane to detect TP antibodies (IgG and IgM) qualitatively and selectively in whole blood, serum or plasma.
INTENDED USE
ACCU-TELL® HBsAg/HCV/HIV/Syphilis Combo Rapid Test 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, type 2 and syphilis antibodies (IgG and IgM) to Treponema Pallidum (TP) 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/Plasma Specimens:
Hold the dropper vertically and transfer 2 drops of serum or plasma (approximately 50μL) to the specimen area, then add 1 drop of buffer (approximately 40μL), respectively. Start the timer. See the illustration below.
For Whole Blood Specimens:
Hold the dropper vertically and transfer 3 drops of whole blood (approximately 75μL) to the specimen area, then add 2 drops of buffer (approximately 80μL), respectively. 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 Rapid Test (Whole Blood/Serum/Plasma) has been tested with a sensitivity panel ranging from 0 to 300ng/ml. All 10 HBsAg subtypes produced positive results on The HBsAg Rapid 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 Rapid Test (Whole Blood/Serum/Plasma) were developed against whole Hepatitis B antigen isolated from Hepatitis B virus. Specificity of the HBsAg Rapid Test (Whole Blood/Serum/Plasma) was also tested with laboratory strains of Hepatitis A and Hepatitis C. They all yielded negative results.

Precision
Intra-Assay
Within-run precision has been determined by using 20 replicates of four different specimens containing different concentrations of HBsAg, HCV antibody, HIV 1.2 antibody and syphilis 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, HIV 1.2 antibody and syphilis antibody. three specimens: a negative, a HCV low titer positive and a HCV high titer positive. Three different lots of ACCU-TELL® HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette (Whole Blood/Serum/Plasma) have been tested over a 3-month period using above negative and positive specimens.

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, HIV 1.2 antibody or syphilis antibody.
4. The HBsAg Rapid 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.
