Which test is most helpful in distinguishing bacterial from viral meningitis?

Meningitis is an inflammation of the fluid and membranes (meninges) surrounding your brain and spinal cord. It has symptoms like headache, fever, and a stiff neck. I heard there are two types of Viral and bacterial meningitis but they have the same symptoms as Sudden high fever, Stiff neck, Sleepiness, No appetite or thirst, and Skin rash. How it is distinguished? How Do We Distinguish Between Viral and Bacterial Meningitis? Which test is most helpful in distinguishing bacterial from viral meningitis?

@ompati Hello, a Spinal tap (lumbar puncture) diagnostic test is done to differentiate between the two. A spinal tap to collect cerebrospinal fluid (CSF). For people with meningitis, the CSF often shows a low sugar (glucose) level along with an increased white blood cell count and increased protein. CSF analysis may also help doctors identify which bacterium caused meningitis. If your doctor suspects viral meningitis, then a DNA-based test known as a polymerase chain reaction (PCR) amplification or a test to check for antibodies against certain viruses to determine the specific cause and proper treatment. Thanks!
