Anti-Japanese Encephalitis Virus Antibody Rapid Test Kit 50 Tests/Kit GMP

1. Principle

This rapid test is an immuno-chromatographic test, using colloidal gold immunoassay method, to detect the antibody against Japanese encephalitis virus in whole blood, serum. After adding sample, the sample move along with the colloidal gold labeling JEV antigen, is there is JEV antibody in the sample, it combines with antigen on T line and show wine-red color; if there is no JEV antibody, then no color reaction.

2. Components

3. Test procedure

1) Collect whole blood, separate serum (centrifuge at 2000-3000 r/min for 5~15min or separate out naturally at 4℃overnight), or take whole blood with anticoagulants as sample. Take whole blood without anticoagulants as sample is also OK, but must test it immediately.
2) Open the package, take out test card, put it on clean, flat desk.
3) Use dropper to absorb the sample, adding 3 drops sample into “S” mark well slowly drop by drop.
4) Judge the result in 10-20min, it is invalid beyond 20min.

4. Results judgment

1) Positive: control line and test line are both seen wine red, the more the antibody exist, the thicker the color appear;

2) Weak positive: control line and test line are both seen wine red, but the color of test line is very light;

3) Negative:only control line is seen wine red;

4) Invalidation: control line isn’t seen wine red.

5. Consults for diagnosis

1) If not vaccinated against porcine JEV virus:
One. There is no visible wine red on the test line, indicating that there is no antibody against the pig JEV virus in the test sample. If the pig is healthy, it is best to vaccinate in time;
b. Visible wine red on the detection line indicates that the pig is infected with wild virus, and more observation and verification should be made.

2) If vaccinated against porcine JEV virus:
One. The color of the detection line is 1:40 darker than the color of the titer. The control card shows that the antibody titer against the swine JEV virus is high enough to resist the strong virus;
b. The color of the test line is thinner than the color of the titer. The 1:40 comparison card shows that the antibody titer against swine JEV virus is not sufficient against strong virus, and supplementary vaccination is better.

6. Storage and expiry date

Store at 2 - 30ºC and the shelf life is 24 months.

7. Notice

1) Do not use expired or poorly packaged test cards;
2) Do not use purified water, tap water and normal saline as negative controls;
3) Store at room temperature (< 30°C). If stored in a cool place, you need to return to normal temperature before opening the package to avoid moisture. Use the test card as soon as possible after opening the package.
4) Do not touch the white film surface in the middle of the test card.
5) To ensure the quality of the test, please take fresh, non-contaminated samples. If there are too many blood lipids, it will affect the results, so after centrifugation, do a serum test to avoid gaining weight. If the blood or serum is viscous or not viscous enough, it can be diluted with normal saline to the same dilution before testing.
6) If serum cannot be detected immediately, it can be stored at 4°C for a short time (within 48 hours) and at -20°C for a long time.
7) Whole blood without anticoagulant should be tested immediately; if some Krull is already present, separate serum for testing. Whole blood containing anticoagulants should be tested within 24 hours and should not be frozen. Freezing and thawing lead to hemolysis and rupture of red blood cells, which seriously affects the test results.
8) When adding the sample dropwise, keep the pipette tip 1cm from the "S" hole to ensure accurate sample addition. If it is too close, the droplet volume will be too small, which will lead to wrong judgment of the droplet or not allow the amount of sample to be added, which will affect the test results.
9) Avoid foaming when adding samples, and the sample volume should be controlled at about 100ul (about 3 drops). Too many samples will not increase sensitivity. In particular, too much whole blood can cause red blood cells to settle in the "wells", causing membrane chromatography to penetrate deep into the red background, seriously affecting the results.
10) This test card is for pig samples only and its applicability to other animals has not been evaluated.
11) Antibody levels are only related to T-line darkness, not C-line. Only the C wire is clean, indicating that the test is valid.
12) Dispose of test cards and samples at the contaminated site according to local regulations.
