Syphilis is a sexually transmitted disease caused by the infection of the pale spirochete. Syphilis specific antibody detection can be used for screening tests, and can also be used to confirm the test, which will be the primary means of diagnosis of syphilis.

The incidence of chronic HCV infection is significantly higher than that of hepatitis B, which is more likely to lead to cirrhosis and liver cancer than that of hepatitis B, and the mortality rate is higher. Therefore, the detection of HCV is of great significance for the early diagnosis and guidanc...

Anti-HBcAb is a marker of hepatitis b virus infection.The core antibody IgM of hepatitis b usually appears in the early stage of hepatitis b virus infection, which is often used in the early diagnosis and prognosis of acute hepatitis b. However, a few chronic hepatitis b patients also showed the co...

Pre-S1 protein plays an important role in virus invasion of hepatocytes. The detection rate of pre-S1 antigen and HBV-DNA is highly correlated, moreover, the S1 antigen can reflect the replication of HBV-DNA more better than the E antigen. In clinical trials, the detection of hbv-dna, combined with...

Outer membrane proteins of Hepatitis B virus (HBV) include three components: S, pre-S2 and pre-S1. Pre-S2 antigen can appear in the serum of patients with acute hepatitis B, the serum is highly contagious and it will decline as the disease recovery. Therefore, pre-S2 antigen is closely related to vi...

Hepatitis A specific antibody( anti-HAV-IgM) appears early, it usually can be detected within a few days, Icteric period reaches its peak. The titer of antibody decreased in January to February, and most disappeared in March to April, which is an important indicators to diagnose Hepatitis B early. ...

At the early stages of hepatitis E virus infection, HEV-IgM antibodies begin to appear, and then HEV-IgG antibodies begin to appear. HEV-IgM and HEV-IgG antibodies can be detected simultaneously, but HEV-IgM disappears during recovery and HEV-IgG persists for a long time. Simultaneous determination ...

HEV IgM appeared earlier, but the maintenance time is shorter. Anti-HEV IgM is positive, indicating the acute phase of HEV infection. The positive of anti-HEV-IgM contributes to the diagnosis of acute hepatitis. Simultaneous the determination of anti-HEV-IgG and anti-HEV-IgM contributes to clinical ...
