This usually indicates that the Lyme disease infection is in its early stages or that the blood test has produced a false positive result. An IgM response may be delayed up to 3 weeks after the infection and so may not be detected at the onset of symptoms such as rash or skin lesion. This means that it doesnt look for the Lyme bacteria directly.
Interpretation of Western blotting and should help most patients navigate their way through some of the medical and scientific terminology associated with the assay. Positive results with clinical history may indicate early stage Lyme disease. Negative IgM Positive IgG Positive Western Blot.
The overall result is positive only when the first test is positive or equivocal and the second test is positive or for some tests equivocal. 08 and 12 Equivocal. Currently there are 9 identified bands specific to Lyme disease 18 23-25 31 34 37 39 83 and 93.
