Viral infections also tend to hide inside the body until they cause serious health issues. That’s where the viral marker test comes into play—identifying the presence of viruses such as hepatitis B, hepatitis C, and HIV even before the signs of symptoms appear. The following is a guide on what viral markers are, why one should undergo the test, and what Indian patients need to know about it. You can know more about viral marker tests through online websites such as Askdocdoc, wherein you can get all the information about the test and also get online consultation regarding your issues.
What Are Viral Marker Tests and Why Are They Done?
Viral marker tests are a series of tests for the detection of specific viral diseases using blood tests. The tests are designed to detect antigens (virus particles) or antibodies (the body’s immune reaction to the virus) in the blood. The viruses most frequently tested for are:
- Hepatitis B and C
- HIV (Human Immunodeficiency Virus)
- Epstein-Barr virus (EBV)
- Cytomegalovirus (CMV)
Physicians usually order viral marker testing before surgery, as part of a routine checkup, during pregnancy, or in those with symptoms of persistent fatigue, liver disease, or sudden unexplained weight loss.
How is the Test Done?
A single drop of patient’s blood is drawn and undergoes a laboratory test for the viral particles or antibodies. Depending upon the suspected virus, the following tests, such as HBsAg, Anti-HCV, or HIV ELISA, are performed. The report is ready in 24-48 hours.
How are Results Interpreted?
- Positive Result: A positive result indicates active or past infection. Confirmatory tests may be required.
- Negative Result: There is no active infection, although follow-up tests might be needed if symptoms or risk of exposure occur.
A doctor needs to be consulted about the test results because they will be done based on immune status and medical history.
Who Should Have a Viral Marker Test?
They are necessary in:
- People with liver disease or abnormal SGPT/SGOT levels
- People undergoing surgery, dialysis, or blood transfusion
- Pregnant women
Individuals with risk behavior or proven exposure to infection
There must be early testing, according to the doctors at AskDocDoc, to prevent delayed diagnosis and provide an opportunity for early treatment, if needed.
What are the Costs and Accessibility in India?
One of the contributing factors to the popularity of viral marker testing in India is that it has become more accessible and cheaper. The test can be found in nearly all diagnostic clinics and hospitals in metro cities and towns. A panel test may cost between ₹600 to ₹2000, depending on the location and lab.
The viral marker test is a powerful force that helps to detect infections early and manage fatal infections. Taking this test at the right time can prevent complications and save your life. As always, refer to a competent health practitioner for advice before and after taking the test to understand your health better.
