How Blood Tests Help Identify the Cause of Back Pain

Are there blood tests for individuals with chronic and severe back pain symptoms that can help healthcare providers diagnose?

Blood Tests To Help Diagnose Back Pain

If a healthcare provider suspects an infection or inflammatory arthritis is the cause of back pain, blood tests may be used to diagnose. When trying to find the cause of back pain, a healthcare provider will examine the patient’s medical history, perform a physical examination, and, if necessary, order diagnostic tests. (Dansie E. J. and Turk D. C. 2013) For example, the National Institute of Arthritis and Musculoskeletal and Skin Diseases says that MRIs can reveal abnormalities in the spine. Still, a person may not feel pain or experience any other symptoms.  The NIAMS also says healthy, pain-free individuals can have elevated SED levels. A high sedimentation rate or sed rate, also known as an erythrocyte sedimentation rate (ESR) test, can indicate inflammation in the body. (National Institute of Arthritis and Musculoskeletal and Skin Diseases, 2023)

Commonly Used Tests

Blood tests that can help diagnose back pain include:

Complete Blood Count – CBC

• This test can indicate inflammation or infections.

Sed Rate or Erythrocyte Sedimentation Rate

• This test measures inflammation by analyzing how red blood cells settle through plasma.
• Inflammation could point to an infection. (Harrison M. 2015)
• If the SED rate indicates that inflammation is present, the possibility of an underlying cause may be some form of arthritis or a tumor, which is rare.

CRP or C-reactive Protein

• Another test that measures inflammation that could indicate an infection or some form of arthritis. (Sproston N. R. and Ashworth J. J. 2018)

HLA-B27

• A genetic marker in the blood that is more common in individuals with ankylosing spondylitis and reactive arthritis. (McMichael A. and Bowness P. 2002)
• This marker may be tested if the healthcare provider suspects either disease.
• Ankylosing spondylitis is an inflammatory arthritis affecting the sacroiliac joints, hips, and spine. (Sieper J. et al., 2002)
• Reactive arthritis is a type that occurs after an infection in a different body system or area. (Hamdulay S. S., Glynne S. J., and Keat A. 2006)
