What is the Parvovirus IgG/IgM Antibodies test?

The Parvovirus IgG/IgM Antibodies blood test detects antibodies produced by the immune system in response to Parvovirus B19 infection. IgM antibodies indicate recent or active infection, while IgG antibodies suggest past exposure and immunity.

Parvovirus B19 is a common viral infection that can cause mild illness in children but may lead to complications in adults, pregnant individuals, or those with weakened immune systems. Antibody testing helps determine infection timing and immune status.

This test is often used when symptoms are unclear, during pregnancy screening, or when investigating unexplained anaemia, joint pain, or viral-like illness.

Why do I need a test for Parvovirus IgG/IgM Antibodies?

Parvovirus infection can present with non-specific symptoms or may be asymptomatic, making antibody testing important for accurate diagnosis. Identifying whether an infection is recent or in the past helps guide clinical decisions and reassurance.

This test is particularly relevant for pregnant individuals, people with chronic anaemia, weakened immune systems, or unexplained joint or flu-like symptoms.

You may benefit from this test if you experience:

• Flu-like symptoms or fever

• Joint pain or swelling

• Skin rash (especially “slapped cheek” rash in children)

• Unexplained anaemia

• Fatigue or weakness

• Exposure to Parvovirus B19

• Pregnancy-related infection screening

• Immune system compromise

Benefits of the Parvovirus IgG/IgM Antibodies test

1. Identifies recent infection
   IgM antibodies indicate active or recent Parvovirus infection.

2. Confirms past exposure and immunity
   IgG antibodies show previous infection and immune response.

3. Supports pregnancy-related assessment
   Helps assess infection risk during pregnancy.

4. Assists investigation of unexplained anaemia
   Parvovirus can suppress red blood cell production.

5. Clarifies cause of joint symptoms
   Useful in adults with viral-related joint pain.

6. Differentiates viral from other conditions
   Helps rule out bacterial or autoimmune causes.

7. Useful in immunocompromised individuals
   Supports monitoring of viral exposure.

8. Provides reassurance through immune status
   Helps confirm immunity or resolution of infection.

Your Parvovirus IgG/IgM Antibodies results explained

Negative antibodies

Negative IgG and IgM results suggest no current or past Parvovirus B19 infection. This means there is no immunity and potential susceptibility to infection.

Further testing may be advised if symptoms persist or exposure is recent.

UK reference interpretation:

• IgG: Not detected

• IgM: Not detected

IgM positive, IgG negative

This pattern indicates recent or acute Parvovirus B19 infection. Symptoms may be present or resolving.

Clinical follow-up may be advised depending on symptoms and individual risk factors.

UK reference interpretation:

• IgM: Detected

• IgG: Not detected

IgG positive, IgM negative

This indicates past infection with Parvovirus B19 and established immunity. No active infection is present.

This result is commonly reassuring, especially in pregnancy.

UK reference interpretation:

• IgG: Detected

• IgM: Not detected
