Immunity Blood Tests: Hepatitis and Rubella
Quick answer: Immunity blood tests check whether you are protected against, or infected with, hepatitis A, hepatitis B, hepatitis C and rubella. At Eunice Women's Clinic near Seongsu Station, these tests help decide whether you need vaccines, especially before pregnancy. Each test costs 20,000 KRW when not covered, and Dr. Eun Mi-na explains the results in English.
What are immunity blood tests?
Immunity blood tests look for antibodies or antigens in your blood. They show whether you have had an infection, whether you are protected (for example after a vaccine), or whether you currently have an infection. At Eunice Women's Clinic, the following tests are on the fee list:
| Test | What it shows | Non-covered price (KRW) |
|---|---|---|
| Hepatitis A IgG | Past infection or vaccine protection | 20,000 |
| Hepatitis A IgM | Recent or current infection | 20,000 |
| Hepatitis B antigen | Current hepatitis B infection | 20,000 |
| Hepatitis B antibody | Protection against hepatitis B | 20,000 |
| Hepatitis C | Past or current hepatitis C infection | 20,000 |
| Rubella IgG | Protection against rubella | 20,000 |
| Rubella IgM | Recent rubella infection | 20,000 |
Who should have immunity tests?
- Women planning pregnancy: rubella infection during pregnancy can harm the baby, so checking rubella immunity before pregnancy is common. See pre-pregnancy checkup.
- Adults unsure of their vaccine history: a test can show whether a vaccine is needed.
- Before hepatitis vaccination: in Korea, hepatitis A is more common in adults who were not exposed in childhood, so many adults check immunity first.
- Workers or students who need proof of immunity for a job, school or visa process.
How do the tests work at the clinic?
- Consultation: the doctor asks about your vaccine history and plans, and suggests which tests are useful.
- Blood draw: one blood sample can be used for several tests.
- Results: the doctor explains which results show protection and which show a need for vaccination.
- Vaccination if needed: the clinic offers hepatitis A, hepatitis B and MMR vaccines.
How should I prepare?
- No fasting is usually needed for these tests.
- Bring your vaccination record if you have one, in any language.
- If you are pregnant or may be pregnant, tell the doctor before any vaccine. MMR is not given during pregnancy.
What do IgG and IgM mean?
IgG and IgM are two types of antibodies. IgM usually appears early in an infection and then decreases. IgG appears later and often stays for years, showing past infection or vaccine protection. For example, a positive rubella IgG with a negative IgM usually means you are protected. For hepatitis B, the antigen test shows current infection and the antibody test shows protection. The doctor explains your specific combination of results.
When will I get my results?
Results usually come within a few days; the clinic will tell you how you will receive them.

Frequently asked questions
Should I check rubella immunity before trying to get pregnant?
Yes, this is commonly recommended. If you are not immune, the MMR vaccine can be given before pregnancy. Pregnancy should be avoided for a period after MMR vaccination; the doctor will explain the timing.
Do I need a test before the hepatitis A vaccine?
It is optional. Many adults in Korea test first because those already immune do not need the vaccine. The doctor can help you decide based on your age and history.
Can I get an English certificate of my results?
Yes. The clinic issues an English medical certificate for 20,000 KRW. Tell the clinic what information the certificate must include, such as test names and results. It is usually ready soon after the results come back.
How many tests do I need?
It depends on your goal. Pre-pregnancy checks often include rubella IgG and hepatitis B tests. The doctor recommends only the tests that fit your situation. Bringing your vaccination record can reduce the number of tests needed.
