Understanding Hepatitis B s (Surface) Antigen, Quantitative


What is Hepatitis B s (Surface) Antigen, Quantitative?

The Hepatitis B s (Surface) Antigen, Quantitative measures the amount of hepatitis B surface antigen (HBsAg) in the blood. This test helps determine if an individual is currently infected with the hepatitis B virus (HBV) and gauge its severity and monitor treatment response.

Hepatitis B is a serious liver infection caused by the hepatitis B virus (HBV). It can spread through contact with infected body fluids like blood, saliva, vaginal fluids and semen. It can also be passed from a mother to her baby during childbirth.

HBsAg is a protein on the surface of HBV that can be detected in high levels in serum during acute or chronic HBV infection. This antigen can be found in your blood within several weeks after the infection starts and therefore serves as one of the earliest markers of a hepatitis B infection. Most infected individuals do not exhibit any symptoms following initial infection. However, some 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 (jaundice). 

The Hepatitis B s (Surface) Antigen, Quantitative test is typically advised for individuals diagnosed with chronic Hepatitis B to monitor the viral load (amount of virus) and evaluate the effectiveness of antiviral treatments. This test is also done during routine follow-up checkups to assess whether the virus is responding to therapy or if adjustments in treatment are necessary. Additionally, the test can be used to gauge disease progression in individuals with high HBsAg levels, which might indicate more severe infection or an increased risk of complications. It may be recommended before starting treatment to establish a baseline viral load and periodically thereafter to track changes in viral activity. In some cases, it is also used to aid in decision-making regarding the need for long-term management or potential interventions to prevent the progression of liver disease.

An elevated HBsAg levels generally signify a higher viral burden, which can be indicative of active infection and increased risk of transmission. Conversely, lower HBsAg levels may suggest a response to antiviral treatment or a reduction in viral replication. 

No special preparation is needed for this test. You may eat and drink as per your daily routine. However, inform the doctor about any medications that you are taking or if you have a history of any bleeding disorders or recent vaccinations, as these factors may influence the test results. 

Lab test results may vary across laboratories. Abnormal test results require an expert interpretation; therefore, don't self-medicate at home solely based on these results, and always consult a doctor for a proper understanding of the test results. 

What is Hepatitis B s (Surface) Antigen, Quantitative used for?

The Hepatitis B s (Surface) Antigen, Quantitative test is done :

  • To diagnose current and past infection with Hepatitis B virus (HBV).
  • To quantify the level of HBsAg in the blood to assess the severity of HBV infection.
  • To screen individuals at higher risk  of HBV infection such as healthcare workers, before an operative procedure etc. 
  • To facilitate prevention of HBV transmission to others, especially newborns or transplant recipients 
  • To monitor the effectiveness of antiviral therapy in individuals with chronic Hepatitis B.

What does Hepatitis B s (Surface) Antigen, Quantitative measure?

The Hepatitis B s (Surface) Antigen, Quantitative test measures the amount of  a specific protein on the surface of the Hepatitis B virus (HBV) in the bloodstream. This protein, HBsAg, serves as a crucial marker for identifying HBV infection and its presence in high levels indicates active viral replication. By quantifying the amount of HBsAg, this test helps determine the viral load, which is crucial for evaluating the extent of the infection and the patient’s infectivity. The Hepatitis B s (Surface) Antigen, Quantitative test is essential for monitoring the effectiveness of treatments such as antiviral therapy, and for implementing measures to prevent the spread of Hepatitis B virus to others. 

Answers to Patient Concerns & Frequently Asked Questions (FAQs) about Hepatitis B s (Surface) Antigen, Quantitative


Frequently Asked Questions about Hepatitis B s (Surface) Antigen, Quantitative

Q. What does the Hepatitis B s (Surface) Antigen, Quantitative measure?

The test measures the amount of hepatitis B surface antigen (HBsAg) in the blood, which indicates the level of Hepatitis B virus (HBV) activity and helps assess the severity of the infection.

Q. When do I need the Hepatitis B s (Surface) Antigen, Quantitative test?

This test is typically performed for individuals diagnosed with acute or chronic Hepatitis B to monitor viral load and assess the effectiveness of antiviral therapy.

Q. What do high levels of HBsAg indicate?

High levels of HBsAg suggest active viral replication and a high viral load, which indicates that the infection is active and the individual may be highly infectious.

Q. What do low or declining levels of HBsAg mean?

Low or declining levels of HBsAg can indicate that the antiviral treatment is effective and the viral load is decreasing, suggesting improved control of the infection.

Q. Can this test determine if I have Hepatitis B?

No, this test measures the amount of HBsAg but does not diagnose Hepatitis B on its own. It is used in conjunction with other tests, such HBsAg qualitative, hepatitis B surface antibody (anti-HBs), total hepatitis B core antibody (anti-HBc), or hepatitis B viral DNA to diagnose and manage the infection.

Q. What are the symptoms of hepatitis B infection?

The symptoms of acute hepatitis B infection may not be apparent for months after exposure to HBV. However, the most common symptoms are fatigue, muscle and joint pain, loss of appetite, dark urine, fever, belly pain, and the yellowing of the eyes and skin (jaundice).

Q. Can hepatitis B spread through food or water?

Hepatitis B virus does not spread through food or water, by sharing utensils, breastfeeding, handholding, coughing, or sneezing. It is primarily transmitted through contact with infectious body fluids such as blood, semen, or vaginal fluids. Also, it can be passed on from mother to child during childbirth.

Q. How is hepatitis B transmitted?

The hepatitis B virus can be transmitted through contact with infected blood and body fluids. This can happen during unprotected sexual contact with an infected partner, from an infected mother to the unborn baby; by sharing needles, syringes, or drug preparation equipment, blood transfusions, organ transplantation; by sharing items such as toothbrushes or razors, due to direct contact with blood or open wounds of an infected person; and by piercing and tattooing. The infection may also spread due to poor infection control in healthcare facilities.

Q. How long is hepatitis B infectious?

Hepatitis B is infectious for as long as the virus is active in your body. If you have an acute infection, it may last from a few weeks to six months, and you can transmit the infection to healthy individuals. If you have a chronic infection, it may last a lifetime and may potentially lead to serious illnesses such as cirrhosis and liver cancer.

Q. How can hepatitis B be prevented?

Vaccination is the best way to prevent hepatitis B. The hepatitis B vaccine is safe and effective and should be given in three doses for complete protection (at 0, 1, and 6 months).

Q. What are the types of hepatitis viruses?

The types of hepatitis virus include hepatitis A, hepatitis B, hepatitis C, hepatitis D, and hepatitis E.
