Rapid Card Test - Hepatitis B Surface Antigen, (HBsAg)

A HBsAg test result signifies that a person has been infected by the hepatitis B virus and can transmit the virus to others as well. After a positive result for the HBsAg test, a doctor may prescribe further testing to determine whether the infection is acute or chronic. Further testing such as viral load measurement or liver function test, may be prescribed to assess the infection’s impact on liver health and determine the most appropriate course of treatment for the next measure.

After a positive HBsAg result, further testing is prescribed to determine if a person has acute or chronic hepatitis B infection. Acute hepatitis B generally goes away by itself with plenty of fluids, rest, and proper nutrition. On the other hand, chronic hepatitis B cannot be cured and must be managed throughout one’s life. In chronic cases, antiviral medications are prescribed to control the infection and prevent potential liver damage. Regular monitoring through HBsAg medical tests is essential to manage the condition effectively and reduce the risk of liver cirrhosis or cancer.

The HBsAg blood test screens for the presence of the hepatitis B virus. Positive results of the HBsAg blood test require further testing to determine whether the patient is suffering from acute or chronic hepatitis B.

Acute hepatitis B generally goes away on its own and a patient is recommended plenty of fluids, rest, and proper nutrition while recovering. In the more severe cases, antiviral medication or hospitalisation may be required as well for effective treatment of the infection.

Chronic hepatitis B infection is not curable but can be managed with lifestyle changes and medication for treating the symptoms and for avoiding liver damage. As chronic hep B can also affect the liver, monitoring the organ’s condition regularly is also important.

Hepatitis B surface antigens are proteins that are present on the surface of the hepatitis B virus. The most accurate test for hepatitis B surface antigen is the HBsAg test, which detects the presence of the antigens as well as certain antibodies in the blood for the diagnosis of hepatitis B. While positive results of the hepatitis B surface antigen test indicate a hepatitis B infection, they cannot classify the infection as acute or chronic, for which, further testing is required. Additional tests like the HBV DNA test help determine the viral load and confirm an active infection. Medical professionals may also recommend booking a Hepatitis B core antibody test to differentiate between acute and chronic infections.

Yes. The HBsAg rapid test is one of the most reliable confirmatory tests for detecting the presence of the hepatitis B virus. The HBsAg rapid test checks for the presence of hep B surface antigens and certain antibodies in the blood, which are only found when a person has been infected by the hepatitis B virus. The test however cannot classify whether the infection is acute or chronic. For a more detailed assessment, additional tests like the HBsAg lab test or Hepatitis B surface antigen serum test are recommended.

The rapid card test for HBsAg allows for the rapid, qualitative detection of the hepatitis B surface antigen in a blood sample. Using the rapid card test for HBsAg offers a simple, quick, and easy-to-interpret procedure for detecting the hepatitis B infection using immunochromatography, where the result can be interpreted in the form of coloured lines that show up (or don’t) in the test region. This test is widely used by medical practitioners for preliminary screening, especially in healthcare settings where quick detection is crucial. However, a confirmatory test may be required in addition to validate the results and assess the infection status accurately.

There are four stages of chronic hepatitis B, which have been explained below:

• Immune Tolerance: Also known as the incubation stage. This is when the hepatitis B virus is replicating rapidly but has not caused too much inflammation. The infection can be detected in this stage by a HBsAg test.
• Immune Clearance or Immune Response: In this stage, the immune system triggers an inflammatory response to destroy the hepatitis B virus in response to the damage caused to the liver by the virus. If this stage persists for more than 6 months, the infection may develop into chronic hepatitis B.
• Immune Control or Inactive Carrier: This is when the body’s immune system is successfully able to suppress the virus and the liver functions start normalising. Complete eradication of the virus leads to the elimination of HBsAg from the blood and the development of HBsAb, which indicates the resolution of infection.
• Immune Escape or Reactivation: This stage signifies the ‘escape’ of the virus from the immune system as it starts replicating again, despite the presence of antibodies.

For some people, the symptoms of being HBsAg positive do not even appear, while for others, symptoms may last for weeks. Ranging from mild to severe, the symptoms that may indicate the need for a HBsAg screening test include:

• Muscle or joint pain
• Pain in the stomach
• Appetite loss
• Mild fever
• Diarrhoea or constipation
• Fatigue
• Yellow tinge in the eyes of the skin
• Brown-coloured urine

A regular HBsAg screening test can help with the early detection of the infection even when mild or no symptoms are showing.

The HBsAg test is confirmatory when it is performed to detect the presence of the hepatitis B virus. The levels of HBsAg in the blood are detectable even in the first stage of infection. However, for categorising the hepatitis B infection as acute or chronic, one would require undergoing more confirmatory tests after the HBsAg.  Additional tests like the Hepatitis B core antibody test or HBV DNA test help determine doctors the stage and severity of the infection. Healthcare professionals may also check the HBsAg standard value to monitor the progression of the disease and further guide treatment plans.

Yes, the HBsAg (Hepatitis B Surface Antigen) rapid test is used to detect the presence of hepatitis B surface antigen in the blood, which may indicate an active hepatitis B infection. It serves as an important screening tool for identifying infected individuals and may be recommended for routine screening, medical evaluations, or monitoring people at risk of hepatitis B infection.

The HBsAg marker is usually one of the first signs of hepatitis B infection to appear in the bloodstream. In many cases, it can be detected within a few weeks after exposure to the virus, often before symptoms develop, making it useful for early screening and timely medical evaluation.

Several factors can affect HBsAg test results, including the stage of infection, viral load, sample quality, immune response, and the sensitivity of the testing method used. Following proper testing procedures and consulting a healthcare professional for interpretation can help ensure accurate assessment of the results.

A rapid HBsAg test provides results quickly and is commonly used for preliminary screening of hepatitis B infection. ELISA-based tests are generally more sensitive and may offer greater accuracy, making them useful for confirming results and detecting lower levels of hepatitis B surface antigen.

Yes, a positive HBsAg result is often followed by additional confirmatory tests to verify the diagnosis and assess the extent of infection. Doctors may recommend further blood tests, viral load testing, or liver function tests to determine whether the infection is acute or chronic and to guide appropriate treatment.
