B型肝炎表面抗原 HBsAg
Hepatitis B Surface Antigen (HBsAg)
*HBsAg is a hallmark protein of the Hepatitis B Virus (HBV). It is detectable in the blood during HBV infection and serves as a key diagnostic marker.
*Normal Range
Negative <1.0 S/CO or nonreactive
Negative: Indicates no current HBV infection or recovery with immunity to the virus.
Positive: Indicates current HBV infection, which could be acute or chronic.
*Significance of HBsAg Positivity
-Acute or Chronic Infection:
HBsAg positivity generally indicates an ongoing HBV infection. If it persists for more than six months, it may suggest chronic Hepatitis B.
-Infectiousness:
Individuals with HBsAg positivity are usually infectious and can transmit the virus to others.
*Health Recommendations
-Early Diagnosis and Treatment:
Seek medical advice if HBsAg is positive. Comprehensive liver function tests and HBV DNA testing are necessary for further evaluation and management.
-Prevent Transmission:
Avoid sharing needles, razors, or other personal items. Use protection during sexual activity and avoid donating blood while infectious.
-Vaccination:
Individuals without HBV infection should receive the Hepatitis B vaccine to prevent infection.
*Conclusion
HBsAg is a vital marker for diagnosing Hepatitis B. Early detection and appropriate treatment can effectively manage the disease and reduce the risk of transmission. Regular screening and vaccination are essential for Hepatitis B prevention and control.
