According to the World Health Organization (WHO), meningitis mortality rate revolves around 10-15% with treatment, 50% without treatment and 10-20% of survivors have permanent disabilities. Meningitis is known as inflammation of meninges, which is the layer surrounding the brain and spinal cord, which diagnostic tests can detect. Such tests may include imaging studies, blood tests, cultures, and a physical examination.

Meningitis can be diagnosed and detected through several procedures, such as:
Doctors will look for symptoms of meningitis, such as high fever, severe headache, stiffness in the neck, nausea, light sensitivity, and changes in mental status. Infant symptoms include irritability, poor feeding, and a bulging skull.
Testing for meningitis starts with a physical exam, in which the doctor measures the probability of meningitis. The doctor will ask about any present illnesses, all symptoms, and when the symptoms started. A few of such tests involve:
A doctor performs this test by flexing the patient's neck toward the chest when the patient is on their back. A person may have meningitis if flexing their knees or hips is difficult.
This test involves lying down, and the doctor bends the knee toward the chest and tries to straighten the leg upward. If doing this hurts the patient or cannot be performed at all, the patient might have inflammation in the meninges, which is predicted to be meningitis.
Some blood test results, like those for meningitis, show an extremely high white blood cell count, which can be used to diagnose a severe infection. A few of those tests include:
It is the gold standard for meningitis diagnosis. Cerebrospinal fluid (CSF) is extracted and analyzed for:
The following blood tests diagnose meningitis:
Before a lumbar puncture, CT (computed tomography) or MRI (magnetic resonance imaging) scans are performed if:
Rapid antigen tests (e.g., latex agglutination) can detect bacterial pathogens (Streptococcus pneumoniae, Neisseria meningitidis); however, they are less sensitive than cultures.
