Hepatitis B Surface Antigen (HBsAg) Test In Ghaziabad - Price & Details

The HBsAg test is a blood test that detects the hepatitis B surface antigen (HBsAg), a protein related to the hepatitis B virus (HBV). Hepatitis B is a viral infection that mainly affects the liver. It may be acute (short-term) or chronic (long-term) and, in some cases, chronic infection can cause liver scarring (cirrhosis), liver failure, or liver cancer. Many people with hepatitis B have no symptoms, allowing the infection to go unnoticed and potentially spread to others. When symptoms do occur, they may include tiredness, fever, nausea, abdominal pain, dark urine, and yellowing of the skin or eyes (jaundice). HBV spreads through infected blood or body fluids, including sexual contact, sharing needles, contaminated medical or personal-care equipment, and from an infected mother to her baby during childbirth. Doctors may recommend HBsAg testing for routine screening, after possible exposure, when hepatitis B is suspected, and during pregnancy. The HBsAg protein can become detectable soon after hepatitis B infection, often before liver function tests become abnormal or symptoms appear. A positive (reactive) result generally indicates a current hepatitis B infection. Early detection allows appropriate follow-up and treatment, and can help reduce the risk of transmission and complications.

• All adults: At least once in a lifetime, regardless of risk factors. Screening is generally done using the HBsAg, anti-HBs, and total anti-HBc triple panel.
• Pregnant women: Routine antenatal testing, ideally in the first trimester.
• Infants: Born to HBsAg-positive mothers.
• People with symptoms: Yellowish eyes and skin (jaundice), fatigue, fever, dark urine, grey or clay-coloured stools, abdominal pain, diarrhoea, nausea, vomiting, joint pain or loss of appetite.
• Known/suspected exposure: People with known or suspected exposure to HBV.

People with ongoing risk of exposure, including:

• History of sexually transmitted infections, multiple partners or practicing unprotected sex
• Past or current hepatitis C infection
• Individuals currently or previously held in a correctional facility or prison
• Birth in HBV-prevalent regions
• Unvaccinated infants of parents from high-prevalence regions
• Injection drug use
• HIV-positive status
• Men who have sex with men
• Household or sexual contacts of an HBV-positive person
• Dialysis patients
• People with diabetes
• Elevated liver enzymes
• Healthcare workers with blood exposure risk
• People who have travelled to high-prevalence countries

The HBsAg test detects the hepatitis B virus itself in the body, hence it is used to detect:

• Active acute hepatitis B: A short-term infection that occurs within the first 6 months after exposure to the virus. Most healthy adults clear the infection on their own and develop lifelong immunity. Symptoms, if present, may include fatigue, jaundice, dark urine, and abdominal discomfort, though many people remain symptom-free.
• Active chronic hepatitis B: Occurs when the immune system is unable to clear the virus within 6 months, resulting in a long-term infection. Chronic hepatitis B often has no noticeable symptoms for years, but it can gradually damage the liver, increasing the risk of cirrhosis and liver cancer over time. It is more common in people infected during infancy or early childhood compared to those infected as adults.

Note: The HBsAg test detects the actual virus (surface antigen), a reactive or a positive result means the virus is currently present and the person is infectious.

What to Expect Before the HBsAg Test?

• No fasting is needed. You can eat and drink normally before the test.
• Prior to the test, inform your doctor about any medicines, supplements, pregnancy status, recent illness, vaccination (especially hepatitis B vaccination), recent transfusion or blood donation history, and exposure to blood or body fluids, as these can affect the test results and interpretation.
• Wear loose-fitting clothing to make blood sample collection easier.
• Inform the phlebotomist if you have a bleeding disorder or are taking blood-thinning medicines before the blood sample is collected.

What to Expect During the Blood Collection?

• The phlebotomist will clean the inside of your arm with an antiseptic and tie a band around your upper arm to make the vein easier to find. You may be asked to make a gentle fist and keep your arm still.
• A small needle will be inserted into the vein to collect a blood sample. You may feel a quick pinprick or mild discomfort that lasts only a few seconds.
• Once enough blood has been collected, the needle will be removed. Gentle pressure will be applied to the area, and a small bandage will be placed over the puncture site.

What to Expect After the HBsAg Test?

• You can get back to your normal routine as soon as the blood sample is collected.
• You may have mild pain or a small bruise where the needle was inserted. This usually goes away on its own within a day or two.
• Your test report is usually available within a few hours. If the result is abnormal, your doctor may recommend other tests to confirm current hepatitis B infection.

Note: If you notice anything unusual at the puncture site, such as persistent bleeding, a rash, or pain, consult your healthcare provider.

The HBsAg test detects the hepatitis B surface antigen, a protein found on the outer coat of the hepatitis B virus. Because it detects a piece of the actual virus, a reactive or positive result means the virus is currently present and the person is infectious.

Note: Unlike anti-HBs or anti-HBc, which detect antibodies produced by the body in response to the virus, the HBsAg test detects a protein from the virus itself, making it a direct marker of active infection. A reactive result should always be confirmed with additional testing (HBV DNA PCR or other tests) and reviewed by a doctor, as it does not by itself distinguish between acute and chronic infection.

Potential Risks and Complications

• The HBsAg blood test is safe and has very few risks.
• You may feel a brief pinprick, mild pain, or notice slight bruising where the blood sample was taken. This usually settles within a few days.
• Some people may feel dizzy or faint after the blood test. There is also a small risk of infection at the needle site.
• Rarely, people with bleeding disorders or those taking blood thinners may have more bleeding or develop a small swelling (haematoma) under the skin.
• These side effects are usually mild and resolve on their own without treatment.

Understanding HBsAg Test Limitations

• This test cannot determine whether the patient had been previously infected with hepatitis B or has immunity to it.
• It cannot determine whether the current infection is acute (short-term) or chronic (long-term).
• It cannot determine the severity of disease or the extent of liver damage.
• A reactive (positive) result may sometimes occur temporarily for a few days after hepatitis B vaccination or due to sample-related or testing factors, even if no infection is present.
• A non-reactive (negative) result may sometimes occur despite infection, if testing was done too soon after exposure, very low levels of the virus are present, or if the causative agent is an HBV variant not detected by the assay.
