The test is intended for home use by the general public to detect IgM antibodies to \u003cem\u003eBorrelia\u003c\/em\u003e bacteria following a recent tick bite.\u003c\/p\u003e\n\u003ch3\u003eGeneral information\u003c\/h3\u003e\n\u003cp\u003eLyme disease is an infection caused by \u003cem\u003eBorrelia\u003c\/em\u003e bacteria, which are spread to humans by tick bites. Ticks are tiny spider-like creatures often found in UK woodlands, parks and gardens.\u003c\/p\u003e\n\u003cp\u003eIt can take the body two to four weeks to produce detectable levels of antibodies after a bite. IgM antibodies are produced first, which increase to a maximum level after about six weeks, but then begin to decline.\u003c\/p\u003e\n\u003cp\u003eOnce transmitted, \u003cem\u003eBorrelia\u003c\/em\u003e bacteria can affect the nervous system, potentially leading to severe neurological disorders. An infection can manifest as skin lesions and arthritis. A characteristic redness of the skin, accompanied by inflammation, may appear at the bite site within three to ten days, or even several weeks post-bite, and may be accompanied by fever.\u003c\/p\u003e\n\u003cp\u003eUpon \u003cem\u003eBorrelia\u003c\/em\u003e infection, the immune system elicits a response characterised by the production of specific antibodies in the blood stream. Immunoglobulin M (IgM), the initial antibody isotype to appear, is detectable within a two to six week post-infection window.\u003c\/p\u003e\n\u003cp\u003eLyme disease exhibits a triphasic progression. During the initial phase (two to four weeks), IgM antibodies are demonstrable in 40 to 60% of affected individuals. In the subsequent phase (four to six weeks post-initial phase), antibody detection rates increase to 70 to 90%. In the final phase, antibodies are typically present and readily detectable.\u003c\/p\u003e\n\u003cp\u003eIf diagnosis and treatment is delayed, some people may develop more severe symptoms months or years after being infected.\u003c\/p\u003e\n\u003ch3\u003eTime to result\u003c\/h3\u003e\n\u003cp\u003eThe test gives a result in 10 minutes at home.\u003c\/p\u003e\n\u003ch3\u003eWarnings\u003c\/h3\u003e\n\u003cp\u003eA test for a single biomarker, such as IgM anti-\u003cem\u003eBorrelia\u003c\/em\u003e antibodies, is not a diagnosis.\u003c\/p\u003e\n\u003cp\u003eDo not change your medication, diet or lifestyle solely on the basis of a self-test - always discuss your result with an appropriate healthcare professional first.\u003c\/p\u003e\n\u003cp\u003eNot following the instructions exactly as written in the instructions for use may cause a false positive or false negative result.\u003c\/p\u003e\n\u003cp\u003eIn the event of a positive result, this test does not determine the stage of illness.\u003c\/p\u003e\n\u003cp\u003eIgM antibody tests for \u003cem\u003eBorrelia\u003c\/em\u003e, whether performed at home with a self-testing kit, or by a hospital laboratory, have significant limitations due to frequent false positive results, including individuals who are sero-positive for cytomegalo-viruses (CMV), Epstein Barr virus, (EBV), herpes simplex virus (HSV), syphilis, leptospirosis, mononucleosis or autoimmune disorders. A self-test result for anti-\u003cem\u003eBorrelia\u003c\/em\u003e IgM antibodies by itself should be viewed with caution until it is followed up by a consultation with a doctor.\u003c\/p\u003e\n\u003cp\u003eWhether you have a positive or negative self-test result, you \u003cstrong\u003emust\u003c\/strong\u003e ask for an urgent GP appointment If you have symptoms of Lyme disease and think you may have been bitten by a tick.\u003c\/p\u003e\n\u003ch3\u003eAccuracy\u003c\/h3\u003e\n\u003cp\u003eThe test has an overall agreement of 89.19% (81.14-94.46)*, sensitivity of 89.09%, and specificity of 89.29% with laboratory tests for anti-\u003cem\u003eBorrelia\u003c\/em\u003e IgM antibodies.
