5. Study Description

Brief Summary
Test and evaluate a new diagnostic method (SRM-MS/MS: Selected Reaction Monitoring- Mass spectrometry) for Lyme Borreliosis on human skin biopsies. Patients included are those with the early skin manifestation (erythema migrans). This new proteomic method will be compared to the two existing method: culture of Borrelia and PCR detection of Borrelia (DNA detection of the bacteria).
