INTRODUCTION
Viral hepatitis is a systemic disease primarily involving the liver. Most cases of acute viral hepatitis are caused by Hepatitis A virus, Hepatitis B virus (HBV) or Hepatitis C virus. The complex antigen found on the surface of HBV is called HBsAg.
Hepatitis C Virus (HCV) is a small, enveloped, positive-sense, single-stranded RNA Virus. HCV is now known to be the major cause of parenterally transmitted non-A, non-B hepatitis.
HIV is the etiologic agent of Acquired Immune Deficiency Syndrome (AIDS). The virion is surrounded by a lipid envelope that is derived from host cell membrane. Several viral glycoproteins are on the envelope.
Treponema Pallidum (TP) is the causative agent of the venereal disease Syphilis. TP is a spirochete bacterium with an outer envelope and a cytoplasmic membrane
INTENDED USE
ACCU-TELL® HBsAg/HCV/HIV/Syphilis Combo Rapid Test Cassette (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 serum or plasma..
TEST PROCEDURE
Allow test cassette, specimen, and/or controls to equilibrate to room temperature (15-30°C) prior to testing.
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. 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 above.
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
Accu-Tell® HBsAg Test (Serum /Plasma) has been tested with a sensitivity panel ranging from 0 to 300 ng/ml. All 10 HBsAg subtypes produced positive results on Accu-Tell® HBsAg Test (Serum /Plasma). The test can detect 1 PEI ng/ml of HBsAg in serum/plasma.
Antibodies used for Accu-Tell® HBsAg Test (Serum /Plasma) were developed against whole Hepatitis B antigen isolated from Hepatitis B virus. Specificity of Accu-Tell® HBsAg Test (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 Cassette (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.
