Anti-Burnet Phage Antibody (IgG) in Serum or Plasma
This test measures the presence of antibodies to the Burnet phage in your blood, which may help identify immune system responses or certain infections.

What Does This Test Measure?
The Burnet phage is a virus-like particle used in research to study immune responses. Antibodies against it can appear in your blood if your immune system has been activated, possibly due to infection, vaccination, or autoimmune conditions.
Why Might You Need This Test?
This test may be used in specialized research or diagnostic contexts to evaluate immune responses, though it is not commonly ordered for routine clinical care. It could be part of broader investigations into immune-related conditions or exposure to certain pathogens.
Sample Collection and Preparation
A blood sample is typically drawn from a vein in your arm. The blood is processed to separate serum or plasma, which is then tested for antibodies against the Burnet phage using immunoassay methods.
What to Expect Before the Test
No special preparation is usually required, but you may be asked to fast for 8–12 hours if instructed by your healthcare provider. Avoid strenuous activity or certain medications that could affect test results if directed.
Reference range
Negative: <1:16; Equivocal: 1:16–1:64; Positive: ≥1:64. Titers of 1:200 or greater with compatible clinical presentation are suggestive of acute Q fever infection.N/A
No special patient preparation is required. Patients with recent exposure to livestock (cattle, sheep, goats) or parturient animals should be advised to inform their healthcare provider due to zoonotic transmission risk.
