HBsAg is an envelope surface protein of the hepatitis B virus and a marker of hepatitis B infection. From the year 2000, the HBsAg reagent requirements have changed according to the progress made the treatment of hepatitis B. Serum levels of HBsAg and their temporal changes over long periods are used to understand the patients’ present clinical state. We have developed a highly sensitive quantitative HBV Blood Testing Reagent Kit to screen for and diagnose acute or chronic hepatitis B virus.Features

- Easy-to-understand directions
- Clear preparation procedures
- Simple specimen collection directions
- Safe and convenient packaging
- Rapid and accurate test results
This kit is an enzyme-linked immunosorbent assay for quantitative detection of Interferon Gamma (IFN-γ) that responds to in-vitro stimulation by Mycobacterium tuberculosis antigens in fresh human whole blood. It is intended for use as an aid in the diagnosis of tuberculosis (TB) infection.
Tuberculosis is a communicable disease caused by infection with M.tuberculosis (MTB)complex organisms (M. tuberculosis, M. bovis, M. africanum), which typically spread to new hosts via airborne droplet nuclei from patients with respiratory tuberculosis disease. It is one of the most important health threatening problems worldwide. The World Health Organization estimates that one third of the world’s population is infected with M.tuberculosis. Each person carrying latent TB infection (LTBI) has approximately a 10% chance of progressing to active disease. Interferon Gamma Release Assay (IGRA) measure a person’s immune reactivity to M.tuberculosis. T lymphocytes from most persons that have been infected with M.tuberculosis will release IFN-γ when mixed with special antigens derived from M.tuberculosis. IGRA is whole-blood test that can aid in diagnosing Mycobacterium tuberculosis infection, including both latent tuberculosis infection (LTBI) and tuberculosis (TB) disease.
