What are the three hepatitis b Antigen system?

Hepatitis b virus (HBV) is a double-layer structure, outside shell, the core of liver virus family.

Under the electron microscope is three forms, namely small spherical particles, tubular particles and large spherical particles.

Large spherical particle is complete the hepatitis b virus particles, also known as Dan's (Dane) particles.

Large spherical particles can be divided into two parts of the shell and core. Large shell of spherical granules, small spherical particles and tubular granules contain hepatitis b surface antigen (HBsAg); large core of spherical granules contain hepatitis b core Antigen (HBcAg) and hepatitis b e Antigen (HBeAg) and 3200 for nucleotide gaps DNA double-strand ring and the DNA polymerase.

Hepatitis b surface antigen (HBsAg), hepatitis b core Antigen (HBcAg) and hepatitis b e Antigen (HBeAg) stimulates the body's generated respectively corresponding to the hepatitis b surface antibody (anti-HBs), hepatitis b core antibody (anti-HBc), hepatitis e antibody (anti-HBe).

HBsAg and anti-HBs; HBcAg and anti-HBc; HBeAg and anti-HBe, three hepatitis b Antigen-antibody system. Three hepatitis b Antigen-antibody system found that greatly facilitated the hepatitis diagnosis, treatment and prevention.

In blood laboratory reports, often mentioned "dasanyang" here means "dasanyang" (not the standard of medical terminology) actually means: hepatitis b surface antigen (HBsAg), hepatitis b e Antigen (HBeAg) and hepatitis b core antibody (anti-HBc) positive.

If HBeAg-negative, anti-HBe positive, other unchanged, so is the "little three Yang".
