How do you test for menengitous?

Lumbar puncture (spinal tap)

A lumbar puncture (spinal tap) is a procedure in which a needle is inserted into the spinal canal to collect a sample of cerebrospinal fluid (CSF). CSF is the clear fluid that surrounds the brain and spinal cord. It can be tested for the presence of bacteria, viruses, and other microorganisms that can cause meningitis.

Blood culture

A blood culture is a test that is used to identify bacteria or fungi in the blood. A blood sample is taken and then incubated in a laboratory for a period of time. If bacteria or fungi are present, they will grow in the culture and can be identified.

Imaging studies

Imaging studies, such as computed tomography (CT) scans and magnetic resonance imaging (MRI) scans, can be used to look for signs of meningitis, such as swelling of the brain or spinal cord.

Polymerase chain reaction (PCR)

PCR is a technique that is used to amplify small amounts of DNA. This can be used to identify the presence of specific bacteria or viruses in a sample of CSF or blood.

Antigen tests

Antigen tests are used to detect the presence of specific antigens, which are proteins that are produced by bacteria or viruses. These tests can be performed on a sample of CSF or blood.
