Book Hepatitis B Surface Antigen (HBsAg) Test

The HBsAg quantitative assay determines how much hepatitis B surface antigen is present in a patient’s blood. This, combined with hepatitis B virus DNA (HBV DNA) testing, allows the doctors to track and evaluate a patient’s response to peginterferon alfa-2a therapy and, if necessary, stop treatment after 24 weeks.

This testing requires no extra preparation and can be taken at any time of day.

HBsAg testing is performed on those who are at high risk of getting hepatitis B, which includes those who.

• Get blood transfusions.
• Have unprotected sexual contact with an infected partner.
• Come into contact with blood (such as health care workers).
• Get a tattoo or acupuncture using contaminated needles.
• Share needles for intravenous drug use.
• Share personal goods (such as a toothbrush, razor, and nail clippers) with a virus carrier.
• Were born to a mother who had hepatitis B.

Hepatitis B testing can be used to diagnose the disease, measure its severity, and identify whether a person is immune to it.

Many people who have chronic hepatitis B have no symptoms. People with acute hepatitis B develop symptoms 2 to 5 months after being exposed to the virus.

These signs and symptoms may include:

• Dark yellow urine
• Tiredness
• Low fever
• Grey or clay-colour stools
• Joint discomfort
• Appetite loss
• Nausea
• Abdominal pain
• Yellowing eyes and skin

When someone has the signs and symptoms of hepatitis B, a doctor or physician may offer this test to detect the presence of the “surface antigen” hepatitis B virus in the patient’s blood.

Hepatitis B is caused by the hepatitis B virus, that leads to liver infection.

The Hepatitis B surface antigen test (HBsAg test) is a blood test that determines whether or not someone has the hepatitis B virus.

Hepatitis B virus (HBV) is one of the world’s most common serious chronic viral illnesses.

HBV is transmitted by contact with bodily fluids. It is most commonly transferred by blood-to-blood contact, although it can also be transmitted during childbirth and infancy, when sharing needles for intravenous drug use, or during unprotected sex.

Acute or chronic hepatitis B infection can occur. Acute hepatitis B is an extremely short term infection. Without therapy, most individuals recover completely from acute hepatitis B within a few weeks to six months.

Approximately five to ten percent of people with acute hepatitis B develop chronic hepatitis B.
Chronic hepatitis is a long-term infection that lasts at least six months. Patients with chronic hepatitis B are more likely to develop consequences such as liver damage, liver failure, and liver cancer.

If you have HBsAg in your blood, it is likely that you are infected with the virus and can spread it to others through your blood or body fluids.

Keep the following considerations in mind:

• You may notice a minor bruise at the puncture site.
• Slight pain in the arm after the test, which can last for a few days.

There is usually no such risk associated with the HBSAG test.
