The clinical data from the clinical trial will be used to assess the performance, sensitivity and specificity of the experimental DualDur In Vitro Diagnostic System.

The clinical data from the clinical trial will be used to assess the performance, sensitivity and specificity of the experimental DualDur In Vitro Diagnostic System.

• The sensitivity of the DualDur in Vitro Diagnostic System will be examined in subjects whose physician indicates drug therapy for Lyme borreliosis (positive arm).
• The specificity of the DualDur in Vitro Diagnostic System will be examined in healthy volunteers declared Lyme borreliosis negative by their physician and all the standard laboratory tests prove that they are free of Lyme borreliosis (negative arm).

The diagnostic system developed by Lyme Diagnostics Ltd. is planned for application in the diagnosis during the entire life cycle of Lyme borreliosis.

• In the preceding 6 months, the patient used an electronic device operating along the principle of electromagnetic (i.e. electric or magnetic) fields - such as bioresonance, pulsed magnetic field, etc. - as add-on treatment for Lyme borreliosis.

II. Negative trial arm

II.1. Inclusion Criteria:

• Man or female subjects over 18 years of age

• Coagulation and/or bleeding disorders
• Anticoagulant therapy
• Participation in another clinical trial

• The patient is under antibiotic therapy, or received such treatment in the preceding 3 months
• The occupation of the subject is either a forester or a hunter

Positive trial arm: At least 18-year-old, treatment-naive or treatment-experienced men and women with Lyme borreliosis, whose physician indicates drug therapy for Lyme borreliosis. Furthermore, they consent to the collection and processing of their data during the clinical trial, and to blood sampling for the assessment of the DualDur IVD System, and to the diagnostic analyses of these samples in the central laboratory of the trial.

Negative trial arm: At least 18-year-old healthy volunteers without the symptoms of either acute or chronic Lyme borreliosis, who have not been treated for Lyme borreliosis, and all the standard laboratory tests prove that they are free of Lyme borreliosis.

Furthermore, they give their consent to blood sampling for the purposes of the clinical trial, to the collection and processing of their data, and to the analyses of their blood samples in the central laboratory of the trial.

To be decided later.
