What's this test for?

This test is ideal if you're experiencing a rash on your face, chest, or limbs, or joint pain and swelling, especially after being around someone with Fifth Disease. It's also useful if you're pregnant and may have been exposed, since parvovirus B19 infection during pregnancy can cause complications. People with sickle cell anemia or other chronic anemia conditions should also consider this test if they suspect exposure, since the virus can trigger sudden, serious anemia in these groups.

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 IgM result means. If your result is positive, keep in mind IgM antibodies can stay elevated for months after an infection, so the timing of your symptoms matters when interpreting the result. If you're pregnant or have a chronic anemia condition and your result is positive, seek medical care promptly since these situations need closer monitoring. You can download the full lab report anytime and track any repeat testing over time using the trends feature.

Who should consider this test?

Anyone with a recent rash, joint pain, or swelling who has been around someone diagnosed with Fifth Disease should consider this test. It's especially important for pregnant women with known exposure and for people with sickle cell disease or other chronic anemias, since parvovirus B19 can cause serious complications in these groups. Parents of school-age children exposed to outbreaks may also want to test if they develop symptoms.

What symptoms indicate I may need this test?
Watch for a red, lacy rash on the cheeks, trunk, or arms and legs, sometimes called a 'slapped cheek' rash. Adults more often notice joint pain and swelling, particularly in the hands, wrists, and knees, rather than the rash itself. If you have a chronic anemia condition and suddenly feel extremely tired, pale, or short of breath, that could signal an anemia flare tied to this infection and warrants prompt attention.
When will I get my results?
Results are typically ready within about 7 days of your lab visit. You'll receive a notification once your report is available in your account, where you can view and download it at any time.
How can I naturally support recovery from a parvovirus B19 infection?
Rest, staying hydrated, and eating a balanced diet with plenty of fruits and vegetables can help your body recover from a typical mild infection. Over-the-counter pain relievers can ease joint discomfort, but check with a pharmacist about what's safe for you. If you have chronic anemia, iron-rich foods and close attention to fatigue levels are especially important during recovery. Most healthy people recover fully within a couple of weeks without any special treatment.
What does a high or positive IgM result mean?
A positive IgM result usually means you've been infected with parvovirus B19 sometime in the recent past, often within the last few months. Because IgM can linger, a positive result doesn't always mean you're currently contagious or symptomatic. If you're pregnant or have a chronic anemia condition, a positive result means you should seek medical care right away to check on your health and monitor for complications.
What does a negative IgM result mean?
A negative result generally means you haven't been recently infected with parvovirus B19, or that it's too early in the infection for antibodies to show up. If your symptoms started very recently, retesting after a week or two may give a clearer picture, since IgM antibodies take some time to develop after exposure. If symptoms are severe or you're pregnant with known exposure, don't rely on a single early negative result alone.
How often should I retest for parvovirus B19?
If your first test was negative but was taken very early in your suspected exposure, retesting one to two weeks later can help confirm the result. There's usually no need for routine retesting once you have a clear positive or negative result matched to your symptom timeline. Pregnant women with ongoing exposure risk may want to discuss a monitoring testing schedule based on their specific situation.
What should I do if my results are abnormal?
If you test positive and are otherwise healthy with mild symptoms, focus on rest, hydration, and symptom relief while you recover. If you're pregnant, have sickle cell anemia, or another chronic anemia condition and test positive, seek medical care promptly since these situations require closer monitoring. Keep a copy of your lab report handy in case you need it for any follow-up care.

What this means

A negative result means no recent parvovirus B19 infection was detected in your blood. This suggests your rash, joint pain, or other symptoms are likely not caused by a recent Fifth Disease infection, unless testing was done very early after exposure.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More advanced tests may take longer due to complexity.
