Overview

The purpose of the Parvovirus B19 Antibody IgG test is to determine whether a person has been previously exposed to parvovirus B19 and has developed IgG antibodies. It is often requested to confirm immunity in pregnant women, to investigate exposure risk, and to help diagnose parvovirus B19 as the cause of symptoms such as fever, rash, joint pain, or aplastic crisis. IgG testing alone does not diagnose an active infection; a positive result should be correlated with IgM serology and clinical findings.

How to Prepare

  • No fasting required.
  • Carry a valid doctor's prescription or requisition if available.
  • Inform the phlebotomist if you have a history of fainting during blood tests.
  • Ensure the sample is labelled with your name and registered identification.

Doctor's Notes

Reviewed by — MBBS, MD (Microbiology) · Reg. No. 27670

"In pregnancy, a positive Parvovirus B19 IgG with negative IgM indicates past immunity and is generally reassuring. A negative IgG identifies a susceptible person who needs counselling and repeat testing after exposure. Results should always be interpreted in clinical context."

Understanding Your Results

Parvovirus B19 IgG results should be read in combination with IgM antibodies, clinical symptoms, blood counts and pregnancy-specific risk factors. The following patterns are commonly used:
📊

No evidence of past or current infection; person may be susceptible. Repeat after known exposure if needed.

📊

Past infection or immunity; active infection unlikely.

📊

Recent or current infection is likely. Clinical correlation and early specialist review are advised, especially in pregnancy.

📊

Possible early/acute infection. Testing should be repeated after 2–3 weeks to confirm seroconversion.

⚠️ When to Consult a Doctor:

Consult your doctor if you are pregnant and have been exposed to parvovirus B19, or if you have fever, rash, joint pain, breathlessness, pallor or any sign of anaemic crisis. Pregnant women should contact their obstetrician for urgent evaluation.

Limitations

  • ⚠IgG test cannot distinguish recent infection from past infection.
  • ⚠Negative IgG in early infection does not exclude parvovirus B19 exposure.
  • ⚠IgM testing is required when acute or recent infection is suspected.
  • ⚠Results should be interpreted along with clinical history and pregnancy status.

Risks & Considerations

  • ●Slight pain or bruising at the venepuncture site
  • ●Dizziness or light-headedness during blood collection
  • ●Rare local infection at the needle site

Interfering Factors

  • ●Sample collected during the window period before seroconversion may be false negative.
  • ●Immunosuppressed patients may not mount a detectable IgG response despite infection.
  • ●Grossly haemolysed or lipaemic samples may affect assay performance.

Frequently Asked Questions

What is the cost of Parvovirus B19 Antibody IgG test at DNA Labs India?
The test costs Rs 4,000 at DNA Labs India. This includes free home sample collection for online bookings. Additional charges, if any, will be informed before sample collection.
What is Parvovirus B19 infection?
Parvovirus B19 is a virus that causes fifth disease, a mild rash illness most common in children. It can cause joint pain in adults and may lead to complications in pregnancy or in people with certain blood disorders.
What does a positive Parvovirus B19 IgG result mean?
A positive IgG result usually indicates past infection or immunity. It does not necessarily mean active infection. To diagnose recent infection, IgM testing and clinical evaluation are required.
Do I need to fast before this test?
No, fasting is not required. You can eat and drink normally before the test.
Who should get this test?
The test is commonly advised for pregnant women exposed to fifth disease, patients with unexplained rash, fever or joint pain, and patients with suspected parvovirus B19-related aplastic crisis.
Is this test done during pregnancy?
Yes, it is often done in pregnancy to assess immunity against parvovirus B19. A positive IgG with negative IgM suggests past immunity and is generally reassuring. All results should be discussed with an obstetrician.
What sample is needed for the test?
A serum sample of 2 mL (minimum 1 mL) is required. Blood is collected in a serum separator tube (SST) by a trained phlebotomist.
How long does the report take?
The report is available the next working day. Samples accepted by 6 pm on Thursday are reported the next day.
How is the test performed?
The test is performed using enzyme immunoassay (EIA/ELISA) to detect IgG antibodies against parvovirus B19 in serum.
Can this test tell if I have an active infection?
No. The IgG test mainly identifies past exposure or immunity. For active or recent infection, a Parvovirus B19 IgM antibody test is more appropriate.
Is home sample collection available?
Yes, DNA Labs India offers free home sample collection for online bookings. This service is available in Mumbai, Delhi, Bangalore, Hyderabad, Chennai, Kolkata and many other cities across India.
What is the difference between IgG and IgM antibodies?
IgM antibodies appear early in infection and indicate recent exposure. IgG antibodies appear later, peak by about one month and may persist for years, indicating past infection or immunity. A doctor may order both for a complete assessment.
