AIDS is a disease that has not been cured by medication so far, so we can also call it a terminal disease, so the population of this disease is now one million, and the number has a very growing trend, so, we can usually check whether we have AIDS through AIDS test strips?
AIDS test strips are a new generation of test reagents developed using colloidal gold immunochromatography technology to detect HIV-1/2 specific antibodies in whole blood, serum or plasma specimens. It is easy to operate, rapid, accurate, comes with quality control and does not require other equipment. It is suitable for clinical testing, blood donation and other places for rapid screening.
A. Principle of HIV test paper The test principle is to use HIV recombinant antigen and sheep anti-mouse IgG fixed in nitrocellulose membrane, and encapsulated with colloidal gold-labeled HIV recombinant antigen and mouse IgG of glass fiber paper and other reagents. The colloidal gold immunochromatographic technique was applied to detect HIV1/2 antibodies in human serum and plasma samples using the principle of double antigen sandwiching. During the assay, blood specimens are added to the spiked wells of the kit, and the samples are first mixed with colloidal gold-labeled HIV recombinant antigen on glass fiber paper sheets, followed by chromatography onto nitrocellulose membrane strips.
If the sample contains HIV1/2 antibodies, these antibodies first bind to the colloidal gold encapsulated with the HIV recombinant antigen, so that when the mixture is chromatographed on the nitrocellulose membrane, it is captured by the detection line (T-line) fixed with the HIV recombinant antigen and forms a double antigen sandwich immune complex of colloidal gold-labeled antigen-antibody-antigen. If there is no HIV1/2 antibody present in the blood of the subject, a red line will not be formed on the test line (T-line), which is a negative result. The quality control line (C line) on the kit is coated with goat anti-mouse IgG, which in any case will bind to mouse IgG-colloidal gold to form a red line on the quality control line to prove that the kit is working properly.
Therefore, AIDS test paper is able to help us check whether we are suffering from this disease, this method is also particularly simple and convenient, we can also quickly know the results through the logo on the test paper, this way is also the preferred way to quickly check patients in the hospital, we all can try this method if we suspect.
Second, the AIDS test paper can detect AIDS is completely detectable, like many hospitals, the CDC primary screening is also used to test the test paper detection, are the national drug “quasi”, the regular qualified products, is a large manufacturer. Single test results are more than 99% accurate, more than two results, the same, to 100%.
Third, how long can be ruled out with HIV test strips 1, 2, 3, 4, 5, 6 weeks after the high risk of HIV testing accuracy are: 30%, 53%, 75%, 84%, 98%, 99.9% or so, 3 months completely excluded. After 2 weeks of high risk, you can start testing in order to gradually release the pressure, 6 weeks for negative can be assured, very few people need 3 months, it is recommended to do a recheck after 3 months.
Fourth, the use of AIDS test paper to pay attention to what test paper in the use is very convenient, no special attention, is disposable supplies, before using patience to read the instructions, according to the instructions to operate, it can be.
1, blood test paper: of course, first to wash your hands clean, check the instructions, and then before collecting blood, slowly and forcefully push the blood from the finger to the fingertip, and then prick the fingertip, so that it is easy to drip blood.
2, saliva test paper: it is best to brush your teeth an hour before the test, then you can drink a glass of plain water, etc. test. Check the instructions, do not use very strong to brush the gum line in the process of detection, do not have gum bleeding for the benefit.
3, the correct way to view the test paper: natural light, the test paper to the hand, and then straighten the arm, and then a glance looks no red line, is negative. Like close look, look in bright light, with a magnifying glass, etc., are wrong.
