What Is a Hepatitis B Core IgM & Total (HBc IgM and Total) Test?
The HBc IgM and total test is a blood test that checks for antibodies produced by the body in response to the hepatitis B virus (HBV). It helps doctors determine whether a hepatitis B infection is new (acute), long-standing (chronic), or from the past. Also known as anti-HBc IgM, and total or HBcAb IgM and total, this test uses a small serum sample drawn from a vein in the arm.
What Does a Hepatitis B Core IgM & Total (HBc IgM and Total) Test Measure?
The Hepatitis B core IgM & total (HBc IgM and total) test analyses two distinct antibodies in the blood. Together, they give doctors a clearer picture of where a hepatitis B infection stands.
The following markers are measured:
| Parameter | What It Detects |
|---|---|
| Anti-HBc total | Both IgM and IgG antibodies against the hepatitis B core antigen indicate current, past, or chronic HBV exposure |
| Anti-HBc IgM | IgM-class antibodies only; these appear during the early, acute phase of infection and typically remain detectable for up to 6 months |
Why Is a Hepatitis B Core IgM & Total (HBc IgM and Total) Test Done?
A doctor may order the HBc IgM and total test when there is a clinical reason to investigate hepatitis B infection or exposure. It plays a key role in separating acute infection from past or chronic disease.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request this test:
- Yellow skin or eyes (jaundice)
- Unusual tiredness or fatigue
- Nausea, vomiting, or loss of appetite
- Pain or discomfort in the stomach area
- Fever
- Joint pain
- Dark urine or pale, clay-coloured stools
Conditions This Test Can Help Detect
This test can help identify several hepatitis B-related conditions:
- Acute hepatitis B infection (a positive anti-HBc IgM result points to a new infection)
- Chronic hepatitis B (a positive anti-HBc total result may indicate long-term infection)
- Past or resolved hepatitis B (negative results for both markers suggest prior infection that has cleared)
- Window period infection, when both HBsAg and anti-HBs are undetectable but infection is present
- Occult hepatitis B, where the virus is present in carriers who test negative for HBsAg and other standard markers
- Acute exacerbation (flare) in a person with known chronic HBV infection
How to Prepare and What to Expect
Preparing for the HBc IgM and total test is straightforward. The steps below will help you feel ready and ensure your sample is collected correctly.
Do You Need to Fast?
No fasting is required before this test. You can eat and drink normally on the day of your appointment.
However, biotin (vitamin B7) intake is an important exception. Stop taking any biotin-containing supplements, including hair, skin, and nail vitamins, at least 72 hours before sample collection. High levels of biotin in the blood can interfere with test accuracy.
Practical Tips Before Your Test
Keep these points in mind before your appointment:
- Stop biotin supplements at least 72 hours before collection
- Drink sufficient water before the blood draw to keep the veins accessible
- Tell your doctor or phlebotomist about all medications and supplements you are currently taking
- Wear a short-sleeved or loose-fitting top for easy access to the arm
Step-by-Step Procedure
Here is what you can expect during sample collection:
- Your identity is confirmed, and the collection site on your arm is cleaned with an antiseptic.
- A trained phlebotomist draws a small blood sample from a vein, usually on the inside of the elbow.
- The procedure takes only a minute or two and causes minimal discomfort.
- A small bandage is placed on the site once the needle is removed.
- The blood sample is placed in a collection tube and processed (centrifuged) as required.
- The sample is sent to the laboratory for analysis, and your results are prepared within the turnaround time.
Factors That Can Affect Accuracy
Certain factors may influence the reliability of your results:
- High biotin intake (20 mg or more per day) can cause false-positive results for Anti-HBc total
- Severely haemolysed samples (broken-down red blood cells) may affect the test
- Microbial contamination of the sample
- Samples stored or transported outside recommended conditions
- Weakened immune system, which may reduce antibody production
- Timing of the test relative to when the infection began
Understanding Your Hepatitis B Core IgM & Total (HBc IgM and Total) Test Results
Your results should always be reviewed alongside other hepatitis B markers, liver enzyme levels, clinical symptoms, and your full medical history. The table below outlines general interpretations.
| Parameter | Result | General Interpretation |
|---|---|---|
| Anti-HBc Total | Negative/Non-reactive | No evidence of past or current HBV exposure |
| Anti-HBc Total | Positive/Reactive | Indicates past, chronic, or current HBV infection |
| Anti-HBc IgM | Negative/Non-reactive | No recent or acute hepatitis B infection detected |
| Anti-HBc IgM | Positive/Reactive | Suggests recent acute HBV infection (within approximately six months) |
A positive anti-HBc total result combined with a negative anti-HBc IgM result typically points to past or chronic hepatitis B rather than a new infection. A positive anti-HBc IgM result confirms a recent or acute infection.
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain health situations can change how results are interpreted:
- In cases of occult hepatitis B, a person may show a positive anti-HBc result alongside a negative HBsAg. HBV DNA testing is usually needed to confirm this.
- In patients receiving immunosuppressive therapy, reactivation of hepatitis B has been reported in 20% to 50% of individuals who test negative for HBsAg but positive for anti-HBc total. This group requires careful monitoring.
- In infants under 18 months born to HBsAg-positive mothers, a positive anti-HBc total result with a negative anti-HBc IgM result may reflect maternal antibodies passed to the baby rather than active infection.
How to Maintain Healthy Levels
These general wellness steps can support liver health and reduce HBV transmission risk:
- Ensure you have received the complete hepatitis B vaccination series if you have no previous HBV exposure
- Avoid sharing items that could carry traces of blood, such as razors or toothbrushes
- Follow safe practices that reduce the risk of bloodborne transmission

Frequently Asked Questions
Anti-HBc IgM detects antibodies produced during the early, acute phase of hepatitis B infection. Anti-HBc total measures both IgM and IgG antibodies, with IgG persisting for life after past or chronic infections. Together, both markers help doctors identify the stage of infection more precisely.
No. The hepatitis B vaccine stimulates antibodies against the hepatitis B surface antigen only. It does not produce core antibodies. So a positive anti-HBc result in a vaccinated person indicates actual exposure to the virus, not a vaccine response.
This combination indicates past or chronic hepatitis B infection rather than a recent acute illness. The IgM antibodies, which signal a new infection, are absent. Your doctor will advise further tests, such as HBsAg or HBV DNA, to clarify the current status.
This can happen during the "window period," a brief phase after HBsAg disappears from the blood but before the anti-HBs antibody becomes detectable. During this time, the HBc IgM and total test may be the only marker that confirms recent infection.
No fasting is needed. However, stop taking biotin supplements (including multivitamins containing vitamin B7) at least 72 hours before your sample is collected. High biotin levels can interfere with the test and affect accuracy.
Anti-HBc IgM is usually detectable in the blood for up to 6 months following an acute hepatitis B infection. After this period, it typically declines to levels that are no longer measurable, which is why early testing is important when acute infection is suspected.
The Anti-HBc IgM portion of the test does not identify chronic carriers, as carriers usually do not produce significant IgM antibodies. A positive Anti-HBc total result may suggest chronic infection, but additional tests, including HBsAg and HBV DNA, are required for a definitive answer.
