INTRODUCTION

Viral hepatitis is a systemic disease primarily involving the liver. Most cases of acute viral hepatitis are caused by Hepatitis A virus (HAV), Hepatitis B virus (HBV) or Hepatitis C virus (HCV). Hepatitis B core antibody is a viral protein secreted by HBV infected cells. Its presence indicates high levels of virus in the blood, and it is an indicator of the infectiousness of the carrier. If this test is negative, but a person is known to be HBcAb positive, then it indicates low levels of virus in the blood or an "integrated phase" of HBV in which the virus is integrated into the host’s DNA.

 

INTENDED USE

ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) is a rapid chromatographic immunoassay for the qualitative detection of Hepatitis B Core Antibody (HBcAb) in serum or plasma.

 

TEST PROCEDURE

HBcAb Rapid Test Cassette Procedure.png

Allow test cassette, serum or plasma specimen, and/or controls to equilibrate to room temperature (15-30℃) prior to testing.

1. Remove the test cassette from the sealed foil pouch and use it within one hour. Best results will be obtained if the assay is performed immediately after opening the foil pouch.

2. Hold the dropper vertically and transfer 3 drops of serum or plasma (approximately 75 μL) to the specimen well of test device and start the timer. Avoid trapping air bubbles in the specimen well. See illustration below.

3. Wait for the colored line is appeared. The result should be read at 15 minutes. Do not interpret the result after 20 minutes.


PERFORMANCE CHARACTERISTICS

*Confidence Intervals

Precision

Intra-Assay

Within-run precision has been determined by using 15 replicates of three specimens containing negative, low positive and high positive. The negative and positive values were correctly identified 99% of the time.

Inter-Assay

Between-run precision has been determined by using the same three specimens of negative, low positive and high positive of HBcAb in 15 independent assays. Three different lots of ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) has been tested over a 3-month period using negative, low positive and high positive specimens. The specimens were correctly identified 99% of the time.

Cross-reactivity

ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) has been tested by HAMA, Rheumatoid factor (RF), HAV, Syphilis, HIV, H. Pylori, MONO, CMV, Rubella and TOXO positive specimens. The results showed no cross-reactivity

Interfering Substances

ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) has been tested for possible interference from visibly hemolyzed and lipemic specimens. No interference was observed.

In addition, no interference was observed in specimens containing up to 2,000 mg/dL Hemoglobin, 1000 mg/dL Bilirubin, and 2000 mg/dL human serum Albumin.

 

LIMITATIONS

1. ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) is for in vitro diagnostic use only. This test should be used for the detection of HBcAb in serum or plasma specimen.

2. ACCU-TELL® HBcAb Rapid Test Cassette (Serum/Plasma) will only indicate the presence of HBcAb in the specimen and should not be used as the sole criteria for the diagnosis of Hepatitis B viral infection.

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