What's this test for?

This test is ideal if a child is experiencing unexplained joint pain, swelling, fever, or difficulty walking or using a limb, especially between the ages of 6 months and 4 years. It helps identify whether a bacterial infection called Kingella kingae is causing joint, bone, or bloodstream problems. Because this bacteria is hard to detect with standard cultures, this test uses a more sensitive method to find it quickly.

What's included in this test?

This test uses a real-time PCR method, a highly sensitive genetic detection technique, to check for the presence of Kingella kingae bacteria. This approach matters because Kingella kingae is notoriously difficult to grow in standard lab cultures, so genetic detection catches infections that older methods might miss.

What happens after I get my results?

Your results will show up in your account as either positive or negative, with a plain-language explanation of what that means. If the result is positive, it's important to act quickly since bone and joint infections in young children can worsen fast, so seeking medical care right away is recommended. A downloadable lab report is available in your account for your records, and you can track any future retests over time using the trends feature.

How can I naturally support joint and bone recovery?
While a bacterial infection like Kingella kingae needs prompt medical treatment and can't be resolved with home remedies alone, supporting the body during recovery helps. Make sure the child gets plenty of rest, stays hydrated, and eats protein and vitamin C rich foods to support tissue healing. Gentle movement, once cleared, can help prevent stiffness, but any specific activity plan should follow directions given after treatment.
When will I get my results?
Results from this test are typically ready within about 7 days of your sample being processed at the lab. You'll receive a notification once your results are posted to your secure online account. Because this test is often used for time-sensitive symptoms, contact the lab if you need to confirm expected timing for your specific sample.
Who should consider this test?
This test is a good option for parents or caregivers of young children showing signs of joint or bone infection, such as limping, refusing to bear weight, fever, or localized swelling. It's especially useful for kids under 4, the age group most commonly affected by Kingella kingae infections. It can also be considered when standard bacterial cultures come back negative but symptoms strongly suggest an infection.
What symptoms indicate I may need this test?
Common signs include sudden joint pain or swelling, refusal to walk or use an arm or leg, fever, and general fussiness or fatigue in a young child. Back pain combined with fever in a child can also point to a spine-related infection called spondylodiscitis. If these symptoms appear suddenly and don't improve, testing can help find the cause quickly.
What does a positive result mean?
A positive result means the genetic material of Kingella kingae bacteria was found in the sample, indicating an active infection. This is considered a significant finding because this bacteria is a leading cause of joint and bone infections in young children and needs prompt attention. Fast action can help prevent joint damage or the infection spreading further in the body.
What does a negative result mean?
A negative result means no Kingella kingae genetic material was detected in the sample, which makes this specific bacteria an unlikely cause of the symptoms. However, if symptoms persist, another cause should still be looked into, since other bacteria or conditions can cause similar joint or bone symptoms. Retesting or additional evaluation may be reasonable if symptoms continue or worsen.
What should I do if my results are abnormal?
If your result comes back positive, seek medical care promptly, since joint and bone infections in children can progress quickly and may need urgent treatment. Keep a copy of your downloadable lab report handy to share during any visit. Watching for worsening symptoms like increased pain, high fever, or reduced limb movement is important while arranging care.

What this means

A negative result means no Kingella kingae bacterial DNA was found in the sample. This suggests this specific bacteria is not the cause of current joint, bone, or bloodstream symptoms. If symptoms persist, other causes should still be looked into.

* 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.
