HBsAg Screening - Rapid
Understanding HBsAg Screening - Rapid
What is HBsAg Screening - Rapid?
An HBsAg Screening - Rapid test helps determine the presence of hepatitis B virus (HBV) infection by detecting hepatitis B surface antigen (HBsAg) in the blood sample. In addition to HBV screening, this test also confirms any previous HBV infection and helps monitor the ongoing treatment for hepatitis B.
Hepatitis B is a viral infection that affects the liver and causes liver inflammation. It is transmitted when the blood, semen, or other body fluids from an infected person enters the body of someone who is not infected. This can happen through sexual contact; by sharing needles, syringes, or other drug-injection equipment; due to infected blood transfusion; or during pregnancy or delivery. Hepatitis B vaccination is the safest and most effective practice to prevent this infection.
Following initial infection, most of the infected individuals do not exhibit any symptoms. However, some of the common symptoms are fever, nausea, vomiting, loss of appetite, stomach pain, joint pain, dark-colored urine, light-colored stool, and the yellowing of skin and eyes. An HBsAg Screening - Rapid test helps to identify individuals infected with the virus and enables the doctor to start appropriate treatment. Early disease detection can prevent complications resulting from the infection and further virus transmission. This test also helps distinguish HBV infection from other forms of hepatitis. The World Health Organization (WHO) recommends testing people who may be at an increased risk of infection, have come in contact with an already infected person, or show the specified symptoms.
Usually, no special preparation is needed for this test. You may eat and drink as per your daily routine. Talk to your doctor about your specific test results. Narrate your complete medical history to help them correlate your clinical and laboratory findings. The test results will help the doctor determine your medical condition and formulate an overall treatment plan.
What is HBsAg Screening - Rapid used for?
An HBsAg Screening - Rapid test is done to:
-
Screen for hepatitis B infection if an individual has been exposed to HBV or has symptoms associated with liver disease.
-
Screen the patients infected with hepatitis C infection if they have risk factors for developing an HBV infection.
What does HBsAg Screening - Rapid measure?
An HBsAg Screening - Rapid test confirms the presence of hepatitis B virus (HBV) in a suspected individual. HBsAg is the first serological marker, within 1 to 10 weeks, to appear in the blood after recent exposure to HBV. Persistence of this marker for more than 6 months implies chronic (long-term) HBV infection which may lead to liver damage (scarring or cirrhosis). A person who has a chronic infection is capable of spreading the infection to healthy individuals, even if they do not show or experience any symptoms.
Interpreting HBsAg Screening - Rapid results
Interpretations
A "Reactive" or "Positive" HBsAg test result means that the person is infected with Hepatitis B virus. If a person tests “positive,” then further testing is required to determine if this is a new “acute” infection or a “chronic” Hepatitis B infection or chronic HBV carrier state.
A "Non-reactive" or "Negative" HBsAg test result means that the person is not infected with Hepatitis B virus.
