Updated: Apr 21, 2016

Laboratory Studies

Laboratory tests are not indicated in the diagnosis of bicycle seat neuropathy. Specific laboratory tests should be ordered based on the clinical consideration for other disorders with similar symptoms of paresthesias or impotence. Tests may include vitamin B-12 and folate levels, a thyrotropin value, a fasting blood glucose level, and a cholesterol panel.


Imaging Studies

Doppler ultrasound of the vascular structures may be indicated.

Consider obtaining plain radiographs or a computed tomography (CT) scan of the abdomen and/or pelvis to rule out pelvic fracture if the patient's history indicates trauma.
