Although phlebotomy is a common and widespread procedure, the medical liter
ature provides limited information in terms of the documented complications
of venipuncture. Documentation of phlebotomy-drelated nerve injuries is ev
en more limited. The authors present a case report of a phlebotomy-induced
lesion of the lateral antebrachial cutaneous nerve. According to our litera
ture search, this is the first case in which electrodiagnostic studies were
used to document venipuncture-related injury of the lateral antebrachial c
utaneous nerve, Specific electrodiagnostic testing is used to definitively
diagnose this rare injury and to track recovery. Electrodiagnostic testing
can be helpful in evaluating cases of sensory disturbance after phlebotomy.
