What is this test?
The Benzene Ring IgG Antibody test is a blood test that measures the presence and level of IgG (immunoglobulin G) antibodies directed against benzene ring structures. Benzene is a chemical compound found in petroleum, tobacco smoke, and certain industrial settings. When the body detects benzene or substances containing benzene rings, the immune system may produce specific antibodies as part of the body's defense response.
How is the test performed?
A healthcare professional will draw a small blood sample from a vein in your arm. The sample is then sent to a laboratory where it is analyzed to detect and measure Benzene Ring IgG antibodies. The procedure is quick and similar to other routine blood tests.
Reference range
Reference values vary by laboratory; results are typically reported as negative, equivocal, or positive based on class-specific IgG antibody levels. Generally, values below 0.35 kU/L are considered negative, 0.35–0.70 kU/L equivocal, and >0.70 kU/L positive.N/A
No special patient preparation is required prior to specimen collection. However, patients should be advised that recent antihistamine or immunosuppressive therapy may affect antibody titers.
