Question

What are normal glucose values in CSF?

a) 0-40 mg/dL
b) 40-70 mg/dL
c) 70-100 mg/dL
d) 100-150 mg/dL

Answer 1

Normal glucose values in CSF range from 50-85 mg/100 ml, and the corresponding correct answer in the provided options is b) 40-70 mg/dL.

Step-by-step explanation:

The normal glucose values in cerebrospinal fluid (CSF) are generally 50-85 mg/100 ml, which is less than plasma glucose levels. When referring to the provided options, the correct answer would be b) 40-70 mg/dL. Glucose levels in CSF may vary in different conditions, such as increasing in cases like encephalitis, central nervous system syphilis, abscesses, and tumors. On the other hand, glucose levels can decrease in purulent meningitis. Inflammatory conditions like encephalitis, central nervous system syphilis, abscesses, and tumors can increase the CSF glucose level. On the other hand, purulent meningitis can cause a decrease in CSF glucose.
