Intended Use

The HBsAg Rapid Test is a Chromatographic immunoassay (CIA) for direct qualitative detection of Hepatitis B type virus surface antigen (HBsAg) in human serum /plasma and whole blood.

Principle

The HBsAg RDT is a chromatographic immunoassay (CIA) for the detection of surface antigens of Hepatitis B in human serum/plasma and whole blood. Specific antibody against HBsAg is pre-coated onto membrane as a capture reagent on the test region.

During the test, specimen is allowed to react with the colloidal gold particles, which have been labeled with anotherr specific antibody.

If HBsAg is present, a pink colored band will develop on the membrane in proportion to the amount of HBsAg presented in the specimen. Absence of this pink colored band in the test region suggests a negative result. To serve as a procedural control, a pink colored band in the control region will always appear regardless the presence or absence of HBsAg.

Reagents and Materials Provided

► One piece of operating instruction with 40 test pouches.

► One sealed pouched cassette with desiccant and a disposable pipette..

► Blood diluent in a dropper bottle. Store at 2-8℃

Sample Collection and Preparation

Whole Blood ( Fingerstick Specimens)

Clean the area to be lanced with an alcohol swab.

► Squeeze the end of the fingertip and pierce it with a sterile lancet.

► Wipe away the first drop of blood with sterile gauze or cotton.

► Use micropipette to obtain about 100ul fresh blood.

Plasma

► Have a certified phlebotomist collect whole blood into a purple, blue or green top collection tube (containing EDTA, citrate or heparin, respectively) by veinpuncture.

► Separate the plasma by centrifugation.

► Carefully withdraw the plasma for testing, or label and store it at 4℃ for up to five days. Plasma may be frozen at -20℃ for at least three months.

Serum

► Have a certified phlebotomist collect whole blood into a red top collection tube (containing no anticoagulants) by veinpuncture.

► Allow the blood to clot.

► Separate the serum by centrifugation.

► Carefully withdraw the serum for testing or label and store it at 4℃for up to five days. Serum may be frozen at -20℃ for at least three months.

Assay Procedure

Serum/Plasma

Add 70-100ul or 2-3 drops of serum or plasma into sample well. Observe the result in 5-20 minutes.

Whole blood
Add 1 drop of whole blood into sample well, after all blood is completely absorbed. Add 1 drop of whole blood diluent. Observe the result in 5-20 minutes.

Interpretation of Results

► Negative: No apparent band in the test region (T), a pink-colored band appears in the control region (C). This indicates that no HBsAg antibody has been detected.

► Positive: In addition to a pink-colored band in the control region (C), a pink-colored band will appear in the test region (T). This indicates that the specimen contains HBsAg.

► Invalid: If no band appears in the control region (C), regardless of the presence or absence of line in the test region (T). It indicates a possible error in performing the test. The test should be repeated using a new device.

Warning and Precautions

► FOR IN VITRO DIAGNOSTIC USES ONLY

► All patient samples should be treated as if capable of transmitting diseases.

► Do not interchange reagents from different lots or use test kit beyond expiration date.

► Icteric, lipemic, hemolysed, heat treated and contaminated sera may cause erroneous results.

Newscen Biopharm Co., Limited is a professional manufacturer of in vitro diagnostic products and related supporting apparatuses, which is jointly founded by Tianjin Pharmaceutical Group, Tianjin Zhongxin Pharmaceuticals Co., Ltd and oversea Chinese entrepreneurs.
