What tests rule out meningitis?
Cerebrospinal fluid test This is the only test that can truly diagnose meningitis. To perform this test, your doctor inserts a needle into your spine in order to collect cerebrospinal fluid (CSF) that’s found around your brain and spinal cord. Then, your doctor sends your CSF to a lab for testing.
How can you tell if meningitis is viral or bacterial?
The clues that the doctor uses are the levels of white cells, protein and glucose in the CSF. Typically in bacterial meningitis the white cell count is much higher than in viral meningitis (and is a different type of white cell), the protein is much higher and the glucose is much lower than in viral meningitis.
Can you have viral meningitis and not know it?
Symptoms of Viral Meningitis Viral meningitis usually begins with symptoms of a viral infection, such as fever, a general feeling of illness (malaise), cough, muscle aches, vomiting, loss of appetite, and headache. However, occasionally, people have no symptoms at first.
Can CT scan detect meningitis?
The CT scan is a valuable tool in diagnosing meningitis. The contrast dye that is injected during the test can highlight brain, skull, and sinus inflammation- all complications and signs of meningitis.
What can mimic meningitis symptoms?
The most common alternative etiologies that mimic viral meningitis are: erhlichiosis, Rocky Mountain spotted fever, Kawasaki disease, and Lyme meningitis. Other conditions sharing some of these symptoms are: drug-associated aseptic meningitis, central nervous system vasculitis, neoplastic diseases.
Which type of meningitis is worse viral or bacterial?
Bacteria or a virus can cause meningitis. Viral meningitis is more common, but bacterial meningitis is more serious. It can lead to brain damage, paralysis, or stroke. In some cases, it can be fatal.
What does a meningitis headache feel like?

What is a meningitis headache like?
A headache caused by meningitis is typically described as severe and unrelenting. It does not subside by taking an aspirin. Stiff neck. This symptom most commonly involves a reduced ability to flex the neck forward, also called nuchal rigidity.
What mimics bacterial meningitis?
Up to age five, the diseases most often suggesting meningitis were right-sided pneumonia, gastroenteritis, otitis, tonsillitis, exanthema subitum, and urinary tract infections.
Can meningitis be seen on an MRI?
Routine contrast-enhanced brain MRI is the most sensitive modality for the diagnosis of bacterial meningitis because it helps detect the presence and extent of inflammatory changes in the meninges, as well as complications.
What tests are performed to rule out meningitis?
– A CSF Gram stain for bacteria; – CSF absolute neutrophil count (ANC) of at least 1,000 cells/ÌL; – CSF protein of at least 80 mg/dL; – Peripheral blood ANC of at least 10,000 cells/ÌL; – A history of seizure before or at the time the patient is seen.
What is the most common cause of meningitis?
Enteroviruses. Coxsackie or Echovirus groups of enteroviruses are the most common cause of viral meningitis.
Which meningitis is worse?
Individual cases of meningitis and encephalitis can vary greatly depending on their cause and severity. Therefore, it is not clear which is more serious and dangerous overall. Viral encephalitis and bacterial meningitis tend to be especially dangerous. All cases of meningitis and encephalitis are serious and need emergent treatment.
What are the first signs of bacterial meningitis?
Symptoms. The symptoms usually come on suddenly,within one week of being exposed to the bacteria.
