HAV IGM Antibody Rapid Test Cassette
HAV IGM Antibody Rapid Test Cassette (甲型肝炎IgM抗体快速检测试纸卡) is a one-step qualitative lateral flow rapid diagnostic test kit, based on the Colloidal Gold Chromatographic Immuno Capture principle, which is used to detect Hepatitis-A IgM Antibody in human Serum, whole blood or plasma specimen.

The standard kit size of this Hepatitis A Card test kit is 25 tests per box; 40 boxes per carton.
To save freight cost, sometimes bulk packing is used, meaning test strip, cassette or multi-test panel is packed in single aluminum pouch; 50 or 100 pouches in one plastic bag; and then plastic bags are packed in cartons along with the unfolded boxes for the test kits. In this way, the customers can easily pack the tests into test kits after receiving the bulk packed goods.

To carry out the assay with a HAV IGM Antibody Rapid Test Cassette, Serum, whole blood or plasma should be collected according to the instructions given in the Instruction For Use included in the test kit. After collecting, it is preferable to perform the testing as early as possible; if not viable, the specimen should be stored properly. A general introduction about the collection, and storage of the specimens is given below.
Serum Collection
Collect blood specimen into a red top blood collection tube by vein puncture, which contains no anticoagulants.
Allow the blood to clot, or separate the serum by centrifugation.
Carefully withdraw the serum into a new pre-labeled tube.
Whole Blood Collection
Whole blood can be collected with blood collection tube with venipuncture into blood collection tube (containing EDTA, citrate or heparin).
Or, by lancet lancing. Clean the area to be lanced with an alcohol swab. Squeeze the end of the fingertip and pierce with a sterile lancet. Wipe away the first drop of blood with sterile gauze or cotton. Take a dropper provided, while gently squeezing the dropper tube, immerse the open end in the blood drop and then gently release the pressure to draw blood into the dropper.
Plasma Collection
Collect blood specimen into a lavender, blue or green top blood collection tube, containing EDTA, citrate or heparin, respectively, by vein puncture.
Separate the plasma by centrifugation.
Carefully withdraw the plasma into a new pre-labeled tube.
Serum, Whole Blood, Plasma Storage Condition
Test specimens as soon as possible after collecting.
The serum and plasma specimens can be stored up to 3 days at 2-8°C if not tested immediately. These specimens should be frozen at -20°C for longer time storage. Don’t freeze and thaw the specimens for many times.
Whole blood specimens (from venepuncture or fingerstick) should be stored at 2~8°C and must be tested within 24 hours after collection. Do not freeze a whole blood specimen.
Prior to testing, bring frozen specimens to room temperature slowly and mix gently.
Specimens containing visible particulate matter should be clarified by centrifugation before testing.
Do not use samples demonstrating gross lipemia, gross hemolysis or turbidity in order to avoid interference on result interpretation.
Colloidal Gold Chromatographic Immuno Capture method is used in this HAV IGM Antibody Rapid Test Cassette to detect the Hepatitis-A IgM Antibody in human Serum, whole blood or plasma specifically. The introduction of this Colloidal Gold Chromatographic Immuno Capture testing principle is given blow.
For the detection of IgM-class antibodies, in order to avoid the interference from the IgG class, capture assays technology is usually the best choice.
In capture lateral flow test kit, a secondary antibody, usually antibody directed to human IgM (anti-human IgM), is immobilized in the test band region on the strip membrane. And monoclonal viral antigen or protein conjugated with colloidal gold particle is embedded in the end of membrane strip.
During the testing process, the sample is added to the end of the membrane strip, the embedded antigen conjugate will resolve into the sample, where the target IgM antibody, if present, will react with and bound to the antigen conjugated with colloidal gold particles.
When the IgM-antigen complex moves to the test band region under the capillary effect, the IgM antibody will be captured by the immobilized anti-human IgM antibody. When the colloidal gold particles congregate in the test band region, a red or pink color will develop, indicating a positive result.
If there is no IgM antibody in the specimen, the antigen conjugated with colloidal gold particle can’t be captured by the anti-human IgM secondary antibody, and no color will develop, indicating a negative result.
