Sugar – Cerebrospinal fluid (CSF):

Why Sugar – Cerebrospinal Fluid Test ?


Glucose can be measured in several body fluids (blood, urine, interstitial fluid, CSF, pleural fluid, ascetic fluid etc), and has an important diagnostic value in terms of various pathologies. CSF is a clear fluid that flows in the space surrounding the brain and the spinal cord. Normal CSF Glucose level is 50 to 80 mg/100dL i.e 2.8mmol/L to 4.4 mmol/L.

High glucose and protein in CSF can arise in conditions in CNS abnormalities. Elevated proteins may be due to any pathology associated with CNS. It may indicate bleeding, tumour, nerve inflammation, injury etc. Moreover, any mass or lump obstructing the blockage in the flow of spinal fluid can cause a rapid buildup of protein in the lower spinal area. CSF Glucose or sugar – CSF can be found in certain abnormal pathologies such as meningitis, inflammatory conditions, sub-arachnoid hemorrhage etc. Hypo-glycorrhachia is the low glucose in CSF, which suggests infection such as bacterial, fungal or tubercular meningitis, inflammatory condition, hypoglycemia, impaired glucose transport, increased CNS glycolytic activity, metastatic carcinoma etc. CSF Glucose test or sugar – CSF Test may be indicated in certain clinical manifestations such as nausea, vomiting, persistent headache, confusion or changes in consciousness, irritability, light sensitivity, severe neck pain or stiffness etc. Abnormal CSF Glucose test or sugar – CSF Test can indicate pathologies such as hemorrhage around the brain, autoimmune disorder, tumours or cancer, idiopathic intracranial hypertension, multiple sclerosis, syphilis, Guillan-Barre syndrome etc. Additional tests include CBC, Differential count, blood glucose, HbA1C (incase of diabetic patient), urine glucose, insulin test, C-Peptide test, cortisol test, glucagon test, protein test in blood and urine, A/G ratio, ESR, D-dimer, CRP, Culture and sensitivity test etc. Other tests include ECG, EEG, imaging studies like CT Scan, MRI etc.
