What's this test for?

This test is ideal if you're experiencing a rash on your face, trunk, or limbs, joint pain and swelling, or you've been exposed to someone with Fifth Disease. It's also useful if you're pregnant and worried about exposure, or if you have sickle cell anemia or another chronic anemia and are concerned about sudden worsening of your condition. The test checks whether you have a current or past parvovirus B19 infection so you can understand your risk and next steps.

What happens after I get my results?

Your results will show up in your account with each antibody level explained alongside its normal range, so you can see exactly where you stand. If your results suggest a recent infection, simple next steps include resting, staying hydrated, and managing joint pain with over-the-counter options, while watching for any worsening symptoms that need urgent care. You can download a standard lab report straight from your account, and if you get tested again later, the trends feature lets you track your antibody levels over time.

What symptoms indicate I may need this test?

Common signs include a red, lacy rash on the cheeks, arms, legs, or trunk, along with joint pain and swelling, especially in adults. Some people also notice mild fever, fatigue, or a runny nose before the rash appears. If you've been around someone diagnosed with Fifth Disease, or if you're pregnant or have a chronic anemia condition and were exposed, these are also good reasons to get checked.

How can I naturally support recovery from parvovirus B19?

Rest and staying well-hydrated help your body fight off the infection on its own, since there's no specific treatment needed for most healthy people. Gentle stretching and over-the-counter pain relief can ease joint discomfort, while a balanced diet rich in vitamin C and iron supports your immune system and blood health. If you have chronic anemia, keeping up with iron-rich foods and staying in close contact about any sudden fatigue or paleness is especially important.

When will I get my results?

Results are typically ready within about 7 days of your lab visit. Once processed, they'll be posted directly to your secure online account, where you can view and download them at your convenience.

Who should consider this test?

Anyone with a rash and joint pain suggestive of Fifth Disease, or anyone recently exposed to a confirmed case, should consider this test. It's especially important for pregnant women who've had contact with an infected person, since parvovirus B19 during pregnancy can cause complications, and for people with sickle cell anemia or other chronic anemias who are at risk for a sudden anemia flare.

What is parvovirus B19 and why does it matter?

Parvovirus B19 is a common virus that causes Fifth Disease, a mild illness with a distinctive rash that mostly affects children but can cause joint pain in adults. It matters because while most people recover without issue, it can cause serious anemia in people with existing blood disorders and can lead to complications if you're infected during pregnancy. Knowing your antibody status helps clarify whether you're currently infected, immune from a past infection, or still at risk.

What does a positive IgM result mean?

A positive IgM result usually means you have a recent or current parvovirus B19 infection, since IgM antibodies show up early and fade within a few months. This is useful information if you're pregnant or have a chronic anemia condition, as it signals you may need closer monitoring during this active phase. Resting and monitoring your symptoms is generally recommended, with urgent care sought if you notice severe fatigue, paleness, or worsening joint swelling.

What does a positive IgG result mean?

A positive IgG result generally means you were infected with parvovirus B19 at some point in the past and your body built long-term immunity. This is generally reassuring news, since it means you're unlikely to get Fifth Disease again or pass on a new infection. If you're pregnant, a positive IgG without a positive IgM is typically a sign of past, not active, infection.

How often should I retest?

If your first test is negative but you were recently exposed, retesting after 2-3 weeks can help catch an infection that hadn't yet triggered an antibody response. Otherwise, this isn't a test most people need to repeat regularly, since antibody status doesn't change once you've developed immunity. Retesting is mainly useful when there's a new exposure, new symptoms, or a new pregnancy where status needs to be reconfirmed.
