Abstract

The invention relates to a magnetic immunochromatographic test strip for combined detection of HIV-1+2 antibody and P24 antigen and a preparation method thereof. The test strip is assembled by pasting a coating film, magnetic particles combined with the HIV-1+2 antibody and the P24 antigen, a sample pad and a water-absorbing pad which are mutually staggered by 2 millimeters in turn on a bottom plate and then covering an upper layer with a transparent plastic sealing film, wherein the coated film is precoated with an HIV-1+2 antibody detection line, an HIV P24 antigen detection line and a quality control line. As the test strip introduces a magnetic immunochromatography technique and a biotin-avidin system into the combined detection of the HIV-1+2 antibody and the P24 antigen, the test strip has the advantages of greatly increasing detection sensitivity result accuracy, shortening detection window period and reducing the labor intensity of operators.

Description

technical field

[0001] The invention belongs to the field of medical testing, in particular to a magnetic immunochromatographic test strip for combined detection of HIV-1+2 antibody and P24 antigen and a preparation method thereof. Background technique

[0002] AIDS, or Acquired Immure Deficiency Syndrome (AIDS), is caused by human immunodeficiency virus (human immunodeficiency virus, HIV). The United Nations Program on AIDS and the World Health Organization jointly released a report stating that in 2006, the number of people living with HIV worldwide was 39.5 million; in 2006, there were 4.3 million new HIV infections; in 2006, 2.9 million people died of AIDS worldwide. According to the "Joint Assessment Report on AIDS Prevention and Control in China (2007)" issued by the Ministry of Health of China, by the end of 2007, there were about 700,000 (550,000-850,000) HIV-infected people and patients in my country, and the infection rate of the whole population was 0.05% (0.04%)....
