What Is a Parvovirus B19 IgM & IgG Antibodies Test?
The parvovirus B19 IgM & IgG antibodies test checks your blood for signs of infection by parvovirus B19, the virus responsible for fifth disease (also called slapped cheek syndrome). It detects two types of antibodies, IgM and IgG, that your immune system produces in response to the virus. Also known as the parvo IgM/IgG test, parvovirus B19 antibody panel, fifth disease antibody test, slapped cheek syndrome test, or B19 virus antibody test, it is ordered when a doctor suspects a current or past parvovirus infection. A small blood sample drawn from a vein is used for this test.
What Does a Parvovirus B19 IgM & IgG Antibodies Test Measure?
The parvovirus B19 IgM & IgG antibodies test measures two distinct types of antibodies in your blood. Understanding the difference helps your doctor pinpoint the timing of infection. The table below explains what each one indicates:
| Antibody | What It Tells You |
|---|---|
| IgM | The first antibody produced after infection. It appears within one to two weeks of exposure, rises quickly, and then fades over the following months. A positive IgM result points to a recent or active infection. |
| IgG | Produced a few weeks after the initial infection to provide longer-term protection. IgG levels stabilise once the infection resolves and remain detectable for life, indicating past exposure or immunity. |
Why Is a Parvovirus B19 IgM & IgG Antibodies Test Done?
Doctors order this test when symptoms or circumstances suggest a parvovirus B19 infection may be present or may have occurred recently.
Common Symptoms That May Require This Test
Several symptoms can prompt a doctor to request the parvo IgM/IgG test. Here are the most common ones:
- A bright red rash on both cheeks, giving a "slapped" appearance
- Fever, headache, or runny nose, particularly in children
- Fatigue and general tiredness that persists
- A lacy, pinkish rash spreading to the trunk, arms, or legs
- Joint pain or stiffness, especially in adults
- Unexplained anaemia or a sudden drop in red blood cell production
- Recent close contact with a person confirmed to have fifth disease
Conditions This Test Can Help Detect
The parvovirus B19 antibody test can help identify a range of conditions linked to this virus. These include:
- Fifth disease (erythema infectiosum), marked by the distinctive facial rash
- Transient aplastic crisis in people with sickle cell disease (a sudden, temporary halt in red blood cell production)
- Severe anaemia, particularly in those with weakened immune systems
- Joint inflammation (symmetric polyarthropathy) affecting small joints
- Hepatitis or myocarditis (inflammation of the liver or heart muscle) in some cases
- Non-immune hydrops (abnormal fluid build-up) in an unborn baby
Parvovirus B19 IgM & IgG Antibodies Test During Pregnancy
The parvovirus B19 IgM & IgG antibodies test is especially important for pregnant women who have been exposed to parvovirus B19 or develop related symptoms. The virus can cross the placenta and affect how a baby's red blood cells develop, potentially causing anaemia in the baby. Serious complications, including miscarriage or stillbirth, are uncommon but carry a higher risk when infection occurs before 20 weeks of pregnancy. Checking immunity status promptly helps doctors monitor and manage the pregnancy appropriately.
How to Prepare and What to Expect
No special preparation is needed before this test, but a few simple steps can help ensure a smooth experience.
Do You Need to Fast?
No fasting is required before the parvovirus B19 IgM & IgG antibodies test. You can eat and drink as normal before your appointment. If your doctor has ordered other tests at the same time, ask whether any of those require fasting.
Practical Tips Before Your Test
Keep the following in mind before you go for sample collection:
- Tell your doctor about any medications or supplements you are currently taking
- Let the laboratory know if you have had a recent illness or viral infection
- If you have had symptoms for at least seven days, or have been recently exposed to someone with fifth disease, mention this when booking
- Pregnant women exposed to a confirmed case of parvovirus B19 should arrange testing promptly
Step-by-Step Procedure
- A trained phlebotomist cleans the skin at your inner elbow or the back of your hand with an antiseptic.
- A small needle is used to draw a blood sample from a vein. This usually causes only brief, mild discomfort.
- About 1.5 mL of blood is collected into a serum separator tube.
- The needle is removed, and a small cotton pad or bandage is placed over the site.
- The sample is processed by centrifuge to separate the serum, then refrigerated and sent to the laboratory promptly.
Factors That Can Affect Accuracy
- Testing too early, before the body has started producing antibodies, may give a false negative
- Very high levels of the virus in the blood during acute infection can sometimes suppress IgM detection
- The presence of other antibodies (such as antinuclear antibodies or Epstein-Barr virus antibodies) may cause borderline IgM readings
- Haemolysed (broken-down) or lipid-rich blood samples may be rejected by the laboratory
- Improperly stored samples can affect accuracy
Understanding Your Parvovirus B19 IgM & IgG Antibodies Test Results
Your results indicate whether specific antibodies were detected in your blood sample. Your doctor will review both readings together to determine what they mean for your health. The table below shows standard reference ranges and what each combination of fifth disease antibody test results may indicate:
| IgM Result | IgG Result | Interpretation |
|---|---|---|
| Positive | Negative | Recent or active Parvovirus B19 infection |
| Positive | Positive | Recent infection with developing immunity |
| Negative | Positive | Past infection; immune to reinfection |
| Negative | Negative | No evidence of past or current 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
Some patient groups require extra care when interpreting parvovirus B19 IgM & IgG antibodies test results. In immunocompromised patients, such as those with HIV/AIDS or those who have had transplants, the immune system may not produce antibodies normally, making results harder to interpret. Similarly, samples collected before the body has begun producing antibodies (prior to seroconversion) may return a negative IgM or IgG result even when infection is present. The reliability of this test in newborns has also not been fully established, and results in this group should be reviewed carefully by a specialist.
How to Maintain Healthy Levels
Because parvovirus B19 spreads through respiratory droplets and close contact, simple hygiene habits offer the best protection. Consider the following:
- Wash hands regularly and thoroughly with soap and water, especially after contact with unwell individuals
- Avoid close contact with anyone who has a confirmed parvovirus B19 infection
- Teach children to sneeze or cough into a tissue or their elbow, and to discard used tissues immediately

Frequently Asked Questions
IgM antibodies appear first, usually within one to two weeks of infection, and are a marker of recent exposure. IgG antibodies develop a few weeks later and persist for life, indicating past infection and immunity. Detecting which type is present helps your doctor determine when the infection occurred.
Parvovirus B19 can cross the placenta and affect how a baby's red blood cells develop. In some cases this leads to foetal anaemia, and in a small number of serious cases it can cause miscarriage, particularly before 20 weeks. Testing a pregnant woman who has been exposed allows doctors to monitor the pregnancy closely and act if needed.
No fasting is required for this test. You can eat and drink normally before your sample is collected. If your doctor has ordered other tests alongside this one, check whether any of those have separate preparation requirements.
No. The parvovirus that affects dogs and cats is a completely different virus and cannot spread to people. Human parvovirus B19 spreads only between people, mainly through respiratory droplets, and cannot be caught from or passed to pets.
Most healthy children and adults recover without problems. However, pregnant women, people with sickle cell disease or other chronic haemolytic anaemias, and immunocompromised individuals (such as those with HIV/AIDS or on chemotherapy) face a higher risk of serious complications and should be tested promptly if exposure is suspected.
IgM antibodies typically appear 10 to 14 days after infection and can remain detectable for up to five months. In some patients, they may persist even longer. Your doctor will consider the timing of your symptoms when interpreting your result.
