Diabetes: Lab Tests for Nerve Problems

Skip to the navigation

Topic Overview

Nerve problems linked with diabetes are most likely caused by diabetic neuropathy , although nerve problems may also be caused by other conditions. Tests that may be done to rule out other conditions include:

  • Complete blood count , which checks red and white blood cell levels, to evaluate a wide range of symptoms.
  • Electrolyte levels , which checks levels in the body such as sodium, potassium, creatinine, glucose, calcium.
  • Thyroid function tests, such as testing for thyroid-stimulating hormone (TSH) levels.
  • Tests to evaluate levels of B12, folic acid, and other vitamins and minerals, to check for deficiencies.
  • Sedimentation rate (ESR), to check for vasculitis and inflammation of the nerves and blood vessels.
  • A test for human immunodeficiency virus (HIV) infection if you and your doctor think you may be at risk.
  • Tests for Lyme disease if you and your doctor think you have been exposed to an infected tick.
