Wann Borreliose nachweisbar?
Blutuntersuchung (Antikörpernachweis) Im Verlauf einer Infektion mit Borrelien bildet die körpereigene Abwehr Antikörper (Immunglobuline) gegen den Erreger. Ab der dritten Erkrankungswoche sind im Blut frühe Antikörper (IgM-Antikörper) nachweisbar und ab der sechsten Krankheitswoche späte Antikörper (IgG-Antikörper).
What does it mean when a Lyme disease test is positive?
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). Most Lyme disease tests are designed to detect antibodies made by the body in response to infection. Antibodies can take several weeks to develop, so patients may test negative if infected only recently.
What is the PCR test for Lyme disease?

The first is a screening test that should detect anyone who might have the disease. Tests that do this well have are regarded as having high sensitivity.
What does a western blot test for Lyme disease look like?
Lyme Disease Test – Western Blot Labs performing a Western blot use electricity to separate proteins called antigens into bands. The read-out from the Western blot looks like a bar code. The lab compares the pattern produced by running the test with your blood to a template pattern representing known cases of Lyme disease.
