Back pain laboratory findings
Introduction
Overview
Overview
There are no diagnostic laboratory findings associated with back pain. However, to investigate the underlying cause of back pain it is crucial to look for the following, complete blood count (CBC), erythrocyte sedimentation rate, C-reactive protein, HLA-B27, antinuclear antibody (ANA), rheumatoid factor, lactate dehydrogenase (LDH), uric acid.
Laboratory Findings
Laboratory Findings
There are no diagnostic laboratory findings associated with back pain. However, to investigate the underlying cause of back pain it is crucial to test for the following:
| Laboratory Test | Pathology Suspected |
| Complete blood count (CBC) | Infections, inflammation |
| Erythrocyte sedimentation rate | Infection, inflammation, arthritis[1] |
| C-reactive protein | Inflammation, arthritis[2] |
| HLA-B27 | Ankylosing spondylitis, reactive arthritis[3] |
| Rheumatoid factor | Rheumatoid arthritis[4] |
| Lactate dehydrogenase (LDH) | Rapid marrow turnover[5] |
| Uric acid | Rapid marrow turnover[5] |
