Hepatitis B Surface Antigen (HBsAg) Test in Jaipur - Price & Details

The HBsAg test is a blood test that detects the hepatitis B surface antigen (HBsAg), a protein associated with the hepatitis B virus (HBV). Hepatitis B is a viral infection that mainly affects the liver and can be either short-term (acute) or long-term (chronic). Although some people develop symptoms such as tiredness, fever, nausea, abdominal pain, dark urine, or yellowing of the skin and eyes (jaundice), many people with hepatitis B have no noticeable symptoms. If hepatitis B becomes chronic, it can cause serious liver problems, including cirrhosis, liver failure, and liver cancer. The infection can be passed to others through infected blood or body fluids, including sexual contact, sharing needles or contaminated equipment, and from an infected mother to her baby during childbirth. This makes testing important, particularly if you may have been exposed to HBV or have symptoms suggesting hepatitis. Early detection can allow timely medical care and help prevent further transmission. HBsAg can become detectable relatively early using the HBsAg test, sometimes before symptoms or abnormal liver function tests develop. A positive (reactive) HBsAg result generally indicates a current hepatitis B infection and may require further testing to assess the infection stage.

• 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?

• Fasting is not required. You can eat and drink normally before the test. The test can be scheduled for any time of day.
• Inform your doctor about any recent illness, your pregnancy status, medicines and supplements, vaccination (especially against hepatitis B), recent transfusions or blood donation history, and exposure to blood or body fluids. Sharing this information helps your doctor interpret your report correctly.
• Wear loose-fitting clothing to make it easier to collect the blood sample from your arm.
• Let the phlebotomist know if you have a bleeding disorder or are taking blood-thinning medications before the blood sample collection.

What to Expect During the Blood Collection?

• Before the blood draw, the phlebotomist cleans the collection site, typically the inner elbow, with an antiseptic swab to reduce infection risk. A tourniquet is then wrapped around the upper arm, and the phlebotomist may gently tap the vein to help it become more visible and easier to access. You may be asked to clench your fist gently and hold your arm steady throughout.
• A sterile needle is inserted into the vein to draw the sample, and you might feel a quick pinprick or mild sting at that moment. Once blood begins flowing into the collection tube, you can relax your hand.
• After collecting the necessary amount, the phlebotomist withdraws the needle and applies gentle pressure to the site to control bleeding. A small bandage is then placed over the area to complete the process.

What to Expect After the HBsAg Test?

• You can resume normal activities right away, as there are no restrictions following the procedure. Mild soreness or slight bruising at the puncture site is common and usually fades within a day.
• Reports are typically ready within 24 hours. If the result comes back abnormal, your doctor will likely recommend further testing before finalising a diagnosis and starting treatment if needed.

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 generally safe, with minimal associated risk. At the blood draw site, you might notice a brief pinprick sensation, mild pain, tenderness, or slight bruising, all of which typically settle within a few days.
• Some people feel light-headed or faint during or shortly after the sample is taken. Infection at the puncture site is also possible, though uncommon.
• In rare cases, excessive bleeding can occur, particularly among those on blood-thinning medication or with underlying bleeding disorders. A haematoma, a small pool of blood beneath the skin causing a raised bruise, may also develop occasionally at the injection site.
• These effects are generally mild and temporary, resolving on their own without specific treatment.

Understanding HBsAg Test Limitations

• Previous infection with hepatitis B or immunity to it cannot be detected through this test.
• It cannot distinguish 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.
• False-positive: A reactive 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.
• False-negative: A non-reactive 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.
