Babesia microti DNA, Real-Time PCR Test
This test uses real-time PCR to detect DNA from Babesia microti, a parasite that infects red blood cells and causes babesiosis, in a whole blood or tick specimen.
About this test
The test detects the presence of Babesia microti DNA using real-time PCR. It identifies this parasite's genetic material specifically, and Quest notes that it does not detect the related canine pathogen Babesia gibsoni. The assay accepts either a whole blood sample or a tick submitted in ethanol.
Quest lists this test's associated name as Babesiosis, the tickborne illness caused by Babesia microti infection. The single analyte reported is the real-time PCR result for Babesia microti DNA: the assay looks for the parasite's genetic material directly, rather than for the antibodies a person's immune system produces in response to infection.

Additional details
What this test looks at
The result is a value describing whether Babesia microti DNA was detected, using real-time polymerase chain reaction (PCR) methodology. Quest accepts either a 0.7 mL whole blood sample collected in EDTA, or a tick specimen submitted in 70% ethanol in a sterile, leak-proof container, as the source material for this test.
This test isn't part of the Celio Health store at the moment, so it can't be ordered or requested here. The test menu lists everything that can.
Laboratory results should always be interpreted by a licensed clinician who knows your health history. This page is information about a test, not medical advice.
Frequently asked questions
What does this test measure?
It detects DNA from Babesia microti using real-time PCR. It does not detect the related organism Babesia gibsoni.
How is the sample collected?
The test accepts either a 0.7 mL whole blood sample collected in EDTA, or a tick submitted in 70% ethanol in a sterile, leak-proof container.
Do I need to prepare for this test?
No preparation instructions are listed for this test, though people follow any instructions their ordering clinician provides.
Is this the same as the antibody test for Babesia microti?
No. This is a PCR test that looks for the parasite's DNA directly, separate from an antibody test that measures the immune response to it.
