Laboratory Tests

Testing may include:

In addition to the tests listed above, a cerebrospinal fluid (CSF) examination may sometimes be ordered if it is thought that the person has meningitis.

Other tests as indicated may be done to help evaluate health status or to rule out other conditions, such as troponin to detect a heart attack.
