Question

what does decreased csf glucose indicate?

Explanation:

Decreased cerebrospinal fluid (CSF) glucose can indicate several conditions. Bacterial meningitis is a common cause as bacteria consume glucose. Fungal or tuberculous meningitis can also lead to low CSF glucose. Malignant tumors in the central nervous system may affect glucose levels. Additionally, hypoglycemia (low blood glucose) can cause low CSF glucose since CSF glucose is related to blood glucose.

Answer:

Decreased CSF glucose can indicate bacterial meningitis, fungal/tuberculous meningitis, malignant CNS tumors, or hypoglycemia.
