What diseases can be diagnosed with a lumbar puncture?

Lumbar puncture, also known as spinal tap, is primarily used to examine diseases of the central nervous system, especially those related to cerebrospinal fluid (CSF). By inserting a needle into the subarachnoid space through the lumbar interspace, CSF can be collected for analysis. This allows physicians to evaluate the characteristics, composition, and pressure of the CSF, aiding in the diagnosis of various conditions such as meningitis, subarachnoid hemorrhage, intracranial infections, and spinal cord disorders. Lumbar puncture is an invasive procedure that must be performed under medical supervision.

Patients should remain relaxed and cooperate with the physician during the procedure. After the puncture, vital signs and symptoms should be closely monitored. Any discomfort should be promptly reported to the doctor.
