What's this test for?

This test is ideal if you're experiencing an unexplained rash, joint pain, or swelling that could point to Fifth Disease, a common viral illness caused by Parvovirus B19. It's especially important if you're pregnant, have sickle cell anemia or another chronic anemia, or have a weakened immune system, since this virus can cause serious complications in those situations. It helps confirm whether an active infection is the reason behind your symptoms.

What happens after I get my results?

Your results will show up in your account with a clear explanation of what a positive or negative result means. If your result is positive and you're pregnant, have anemia, or have a weakened immune system, seek medical care right away since follow-up monitoring may be needed. You can download a standard lab report from your account at any time, and if you're retested later, the trends feature lets you track results over time.

What's included in this test?

This test measures Parvovirus B19 DNA in your blood using real-time PCR technology. Detecting the virus's genetic material directly is the most reliable way to confirm an active, ongoing infection rather than a past exposure, and it can guide decisions about treatment and help assess the risk of spreading the infection to others.

Who should consider this test?

This test is a good fit for pregnant women who've been exposed to Parvovirus B19, people with sickle cell anemia or other chronic anemias, and anyone with a weakened immune system who has symptoms. Parents of children with an unexplained facial rash, or adults with sudden joint pain and swelling, may also want to consider it. It's especially useful when a fast, direct answer about active infection is needed.

When will I get my results?

Results are typically ready within about 7 days of your sample being collected. You'll be notified as soon as your report is available in your account, so there's no need to call or follow up separately.

What symptoms indicate I may need this test?

Common signs include a red rash on the face, chest, or limbs (sometimes called a 'slapped cheek' look in kids), along with joint pain and swelling, which is more typical in adults. Fatigue, mild fever, and a general feeling of being unwell can also show up. If you have chronic anemia and suddenly feel more tired or short of breath, that combination is worth checking out too.

How can I naturally support recovery from a viral infection like this?

Rest, staying well-hydrated, and eating nutrient-rich foods can help your body fight off the infection on its own, since most healthy people clear Parvovirus B19 without specific treatment. Over-the-counter pain relievers can ease joint discomfort, and gentle movement may help stiffness. If you have anemia or a weakened immune system, don't rely on home care alone — seek medical attention promptly.

What is Parvovirus B19 and why does it matter?

Parvovirus B19 is a common virus that causes Fifth Disease, an illness that mostly affects children but can also infect adults. While it's usually mild, it matters because it can trigger serious anemia in people who already have blood disorders and can cause complications during pregnancy. Knowing whether you're actively infected helps you take the right precautions for yourself and people around you.

What does a positive result mean?

A positive result means the virus's DNA was found in your blood, confirming an active infection rather than one you had in the past. For most healthy people, this simply means your body is fighting off the virus and symptoms should resolve on their own within a couple of weeks. If you're pregnant, immunocompromised, or have chronic anemia, a positive result means you should seek medical care promptly to monitor for complications.

How often should I retest?

Retesting isn't usually needed once you've recovered, since the virus clears from your blood over time. However, if you're being monitored for a persistent infection or you're immunocompromised, retesting every few weeks can help track whether the virus is still active. Your report's trends feature makes it easy to compare results if you do retest.
