How Is Transverse Myelitis Diagnosed? Tests, Criteria & Process
Transverse Myelitis diagnosis relies on Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis. Learn the full diagnostic pathway, clinical criteria, differential workup, and what to expect at your evaluation.
Updated March 27, 2026
Transverse Myelitis is diagnosed using Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis and targeted clinical evaluation. Transverse myelitis is inflammation across both sides of the spinal cord, causing weakness, sensory changes, and bladder dysfunction below the level of inflammation. It can be idiopathic or associated with multiple sclerosis or neuromyelitis optica.
Clinical Context
The diagnostic process for Transverse Myelitis begins with Thorough history and physical examination followed by basic blood and urine tests; targeted specialist investigation as needed. Key investigations include Full blood count (FBC), Comprehensive metabolic panel (electrolytes, creatinine, LFTs), Urinalysis, Chest X-ray. The gold standard is: Directed investigation based on clinical history and physical examination findings. Clinical guidelines from NICE / BMJ Best Practice / WHO define the diagnostic criteria and recommended investigation pathway.
