HBsAg TestThe Hepatitis B Surface Antigen (HBsAg) test detects the presence of the hepatitis B virus (HBV) in the body. It detects the hepatitis B surface antigen in the blood, indicating an active infection. This test is crucial for early diagnosis, treatment planning, and preventing the spread of hepatitis B.Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). It can spread through contact with infected body fluids like blood, saliva, vaginal fluids, and semen. It can also be passed from a mother to her baby during childbirth.HBsAg is a protein on the surface of the hepatitis B virus (HBV) that appears in the blood within a few weeks of infection. It is one of the earliest markers of hepatitis B and indicates that a person is infectious. Many people do not show symptoms initially, but some may experience fever, nausea, vomiting, loss of appetite, stomach pain, joint pain, dark urine, pale stools, and yellowing of the skin and eyes (jaundice). Persistent HBsAg may indicate chronic hepatitis B or carrier status.The Hepatitis B Surface Antigen (HBsAg) test is recommended for people who show signs of hepatitis, those at higher risk of hepatitis B (like healthcare workers, people using injectable drugs, or those with multiple sexual partners), during routine health checkups, before surgery, or for job screenings, after vaccination, and for babies born to hepatitis B-infected mothers. Pregnant women are also tested to prevent the virus from being passed to their baby. Early detection helps start treatment early and prevent serious liver problems like cirrhosis or cancer.No special preparation is needed for this test, and you can eat and drink normally. Please inform your doctor about any medications or recent vaccinations, and provide a complete medical history to help them accurately interpret the results.Lab test results require expert interpretation; therefore, never self-medicate at home solely based on these results. Always consult a doctor for a proper understanding of the test results.
