This test helps find a recent or active hepatitis B infection by detecting special immune markers (called IgM antibodies) in your blood. These markers appear when your immune system is fighting the hepatitis B virus, which affects your liver. Doctors use this test to tell if you have a new infection, need special care, or might spread the virus to others. It is important for keeping your liver healthy and protecting others from getting sick.

Why is it Important:

Diagnosis of New Infection: This test is the main way to find out if someone has just gotten hepatitis B, which can help doctors start care quickly and prevent it from spreading to others.
Detects Silent Infections: Even if you do not feel sick, this test can show if you were recently infected, as hepatitis B sometimes does not have clear symptoms at first.
Decides Your Next Steps: If the result is positive, your doctor may recommend further tests, treatment, and monitoring to keep your liver healthy and avoid serious complications such as cirrhosis or liver cancer.
Prevents Confusion: It separates recent (acute) infections from long-term (chronic) cases, helping doctors know if your body is fighting off a new infection or handling an old one.
Supports Public Health: Identifying acute cases early helps protect friends, family, and others from unintended transmission of the virus.

When Should I Get This Test?

You should consider this test if you:

Experience symptoms like yellow skin or eyes, dark urine, tiredness, or stomach pain.
Have been in close contact with someone who has hepatitis B or may have been exposed through blood, needles, or unprotected sex.
Are pregnant, as hepatitis B can be passed to your baby.
Need to check your hepatitis B status before surgery, starting certain medications, or as part of a health checkup.
Are at risk due to your job (such as healthcare workers), travel, or living in areas where hepatitis B is common.

Interpretation of Test Results:

Understanding what your results might mean is helpful, but always discuss them with a doctor

for a proper diagnosis.

Result Type	What it Means
Negative/Normal	No recent or active hepatitis B infection detected.
Borderline	The result is unclear. May need more tests or a repeat test to confirm.
Positive/Abnormal	Indicates a recent or active infection with hepatitis B virus. Further evaluation needed.

(Note: Specific normal ranges can vary slightly between labs and depending on individual factors. Always refer to the ranges provided on your report and consult your doctor.)

Additional Information:

This test alone cannot tell if you have a chronic infection or are completely cured, so your doctor may order more tests for a complete picture.
If you get a positive result, avoid sharing personal items like razors or toothbrushes to protect others from the virus.
Regular check-ups are important to monitor your liver health and prevent future problems.

Test Requirements:

Sample Type: Blood sample (serum).
Test Preparation: No fasting or special preparation is required.
Precautions: Inform your doctor about any medicines or medical conditions before the test. Follow general hygiene rules for blood draws.

FAQs

Do I need to fast before the Hepatitis B Core Antibody IgM test?
No, fasting is not needed for this test. You can eat and drink as usual unless your doctor advises otherwise. This makes it easy and comfortable—a small blood sample is all that’s needed.
What does a positive result mean for the Core Antibody IgM test?
A positive result means your body is fighting a recent or new hepatitis B infection. Your doctor will use this information, along with other tests, to guide your care and next steps.
Is the test safe to do during pregnancy?
Yes, it is safe. The test uses a simple blood sample. Pregnant women may be tested to protect their own health and prevent passing the virus to their baby. Always tell your doctor if you are pregnant.
I have no symptoms—should I still get tested?
Yes, sometimes hepatitis B doesn’t show any signs early on. If you’ve been exposed or are at risk, getting tested can help find silent infections and allow early treatment to protect your liver.
What should I do if my result is abnormal?
If your result is abnormal, contact your healthcare provider. They may suggest more tests, treatments, or steps to protect your health and keep others safe. Do not try to interpret results on your own—always get expert advice.
