Supportive Data

The following assay verification data supports the use of this assay for clinical testing.

 

Accuracy/Diagnostic Sensitivity and Specificity:

The sensitivity and specificity of the polymerase chain reaction (PCR) assay using clinical and spiked specimens are 100%.

 

Analytical Sensitivity/Limit of Detection:

The limit of detection is 2800 target copies/mL (5.6 target copies/mcL) of whole blood or spinal fluid.

 

Analytical Specificity:

No PCR signal was obtained from the extracts of 31 bacterial, viral, parasitic, and fungal isolates from similar organisms or from organisms commonly found in the specimens tested.

 

Precision:

Interassay and intra-assay precisions are 100%.

 

Reference Range:

The reference range of this assay is negative. This assay is designed to detect only species of clinical significance and is to be used for patients with a clinical history and symptoms consistent with tick-borne relapsing fever. It should not be used to screen healthy patients.

 

Reportable Range:

This is a qualitative assay, and the results are reported as negative or positive for Borrelia miyamotoi DNA.
