Tested positive for hepatitis? AIIMS doctor explains what your report really means

A positive hepatitis test can be frightening, but doctors say it does not always mean you have an active infection or need immediate treatment. Understanding which hepatitis test is positive is the key to knowing what happens next.Positive hepatitis test needs confirmationSeeing the word "positive" on a blood test can be enough to cause sleepless nights. Many people immediately assume they have liver damage, are infectious to others, or will need lifelong treatment. But doctors say that is not always the case.According to Dr Ajeet Singh Bhadoria, Professor, Department of Preventive Hepatology and Community Medicine, AIIMS Rishikesh, a positive hepatitis test should never be interpreted in isolation. The most important question is not whether the test is positive, but which test is positive and what it actually measures."There are different types of hepatitis viruses, and different laboratory tests look for different markers," he explains. "Some tests show that your body has been exposed to the virus in the past, while others confirm whether the virus is currently active."This distinction is important because millions of people undergo hepatitis screening every year. While some may have an active infection that needs treatment, others may have recovered naturally, developed immunity through vaccination, or simply require additional tests before any diagnosis can be confirmed. Here's what every positive hepatitis test really means.THERE ARE FIVE TYPES OF VIRAL HEPATITISThe five common hepatitis viruses are: Hepatitis A (HAV)Hepatitis B (HBV)Hepatitis C (HCV)Hepatitis D (HDV)Hepatitis E (HEV)Although all of them affect the liver, they spread differently.Hepatitis A and E are usually transmitted through contaminated food or water and typically cause short-term illness.Hepatitis B, C and D spread through infected blood and body fluids. These infections can become chronic and increase the risk of liver cirrhosis, liver failure and liver cancer if left untreated.A POSITIVE TEST DOES NOT ALWAYS MEAN YOU HAVE AN ACTIVE INFECTIONOne of the biggest misconceptions about hepatitis is that every positive test confirms active disease.Dr. Bhadoria says this is not true.Different laboratory tests look for different things:Antigen tests detect parts of the virus and often indicate a current infection.Antibody tests show that the immune system has encountered the virus at some point.DNA or RNA tests detect the virus itself and confirm whether it is actively multiplying.This is why doctors almost always order additional tests after an initial positive screening result.WHY HEPATITIS C OFTEN NEEDS A SECOND TESTFor hepatitis C, the first screening test usually checks for Anti-HCV antibodies. A positive antibody result simply means the immune system has seen the virus before. It does not prove that the virus is still present. Some people clear hepatitis C naturally without treatment. Others remain antibody-positive even after successful treatment.To know whether the infection is active, doctors perform an HCV RNA test, which detects the virus's genetic material in the blood. Only if this test is positive is hepatitis C considered an active infection that requires treatment.HEPATITIS B TESTING IS MORE COMPLICATEDUnlike hepatitis C, hepatitis B requires several blood markers to understand what is happening.Doctors may check:HBsAg to identify a current infection.Anti-HBs to determine immunity after vaccination or recovery.Anti-HBc to show previous or current exposure.HBeAg to assess how infectious a person may be.HBV DNA to measure active viral replication and decide whether treatment is needed.Doctors interpret these results together rather than relying on a single test.TIMING CAN CHANGE THE RESULTWhen someone is tested soon after exposure, the virus may not yet be detectable. This is known as the window period. In hepatitis C, viral RNA often appears before antibodies develop. On the other hand, antibodies may remain positive for years even after the infection has completely resolved.That is why doctors also consider:SymptomsRecent exposureVaccination historyPrevious treatmentImmune statusBefore making a diagnosis.WHAT ABOUT HEPATITIS A AND E?Hepatitis A and E usually spread through contaminated food or water.People often develop symptoms such as:JaundiceFeverNauseaLoss of appetiteFatigueDoctors usually diagnose these infections using IgM antibody tests.The good news is that both infections are usually short-lived and most people recover completely with supportive treatment. Only a very small percentage develop severe liver failure.WHY CONFIRMATORY TESTING MATTERSAccording to Dr Bhadoria, one of the biggest mistakes patients make is assuming that the first positive report tells the whole story.Instead, screening tests are designed to identify people who may need further evaluation.Confirmatory molecular tests help doctors determine:Whether the virus is activeWhether treatment is necessaryHow infectious the person isWhether the liver has already been affectedWithout these follow-up tests, patients may either panic unnecessarily or miss treatment when they actually need it.INDIA IS EXPANDING HEPATITIS SCREENINGIndia continues to face a significant burden of hepatitis B and hepatitis C, with millions of people estimated to be living with chronic infection.Many remain undiagnosed because hepatitis often causes few or no symptoms in its early stages.Under the National Viral Hepatitis Control Programme, the government has expanded access to free screening, confirmatory testing and treatment through public health facilities.The country has also strengthened its diagnostic network by deploying molecular testing platforms such as Truenat, making confirmatory testing more accessible, especially in areas where advanced laboratories are limited.A positive hepatitis test should never be viewed as the final diagnosis.It is simply the first step in finding out whether the virus is currently active, whether you have recovered from a past infection, or whether you are protected through vaccination.Doctors stress that interpreting hepatitis test results requires looking at the complete picture, not just one laboratory report. With confirmatory testing and timely follow-up, patients can receive the right treatment while avoiding unnecessary anxiety and confusion.- EndsPublished By: Smarica PantPublished On: Jul 28, 2026 07:30 IST
