This is a blood test for IgM and IgG antibodies to the bacterium Borrelia burgdorferi, which is transmitted to humans through the bite of infected ticks. These ticks are about the size of a pin-head and in susceptible people, infection can cause Lyme disease. A common early sign of infection is a circular, expanding rash which has the appearance of a bull’s eye. If you have this rash, you have been infected and do not need to proceed with this test, you should instead consult your doctor.
This rash doesn’t however occur in all cases and unfortunately there isn’t an easy single test to categorically diagnose Lyme disease. IgM and IgG antibodies to the bacterium Borrelia burgdorferi can help to confirm infection, but it is known for producing false positive results in people with glandular fever, rheumatoid arthritis and other autoimmune conditions. If you have a positive result then we would advise you are further assessed by your doctor.
Important: A Lyme disease test can be negative if taken too soon after the infection date. If you are free of symptoms please wait for at least 6 weeks after the date you suspect you were bitten or were in an environment where you could have been infected. If you are experiencing symptoms then we recommend testing as soon as possible.
