#ExistInterpData>
LI = Lyme Index The detection of antibodies of Borrelia burgdorferi in CSF may indicate central nervous system infection. However, consideration must be given to possible contamination by blood or transfer of serum antibodies across the blood-brain barrier. Please refer to Statement E in the Compliance Statements section in the front of the Laboratory Test Directory. *ExistInterpData> |
