It is the main sugar in the blood and the major source of energy. It is taken in foods or the body can make it from triglycerides and proteins.
Interpretation: Glucose levels are controlled by different hormones in the body,where the main ones are insulin and glucagon. High glucose levels lead to Diabetes(Type I and II) where insulin cannot help glucose enter the cells for energy. This results in high thirst, urination, weight loss, fatique and increased apetite symptoms. Low glucose levels (hypoglycemia) might be because of prolonged fasting, high insulin levels (insulinomas), severe exercise and some other diseases which the clinician will diagnose. Cerebrospinal fluid (CSF) glucose may also be tested to diagnose hypoglycorrhacia(Low CSF glucose) which happens in central nervous system infections, Inflamatory condutions, subarachnoid hemorrhage, impaired glucose transport and metastatic carcinoma. CSF glucose levels are also used to distinguish meningitis causes.. In bacterial meningitis, CSF glucose levels decrease where in viral meningitis glucose levels are normal. Urine glucose levels are used to diagnose diabetes in which uine glucose is detected after 180 mg/dl blood levels which exceeds the clearance capacity of the kidney. This condution will damage kidney tubuli if not treated.
