    CSF smear

    Spinal fluid smear; Cerebrospinal fluid smear

    A cerebrospinal fluid (CSF) smear is an exam of the fluid that moves in the spacearoundthe spinal cord and brain. CSF protects the brain and spinal cord from injury.

    How the Test is Performed

    A sample of CSF fluid is needed. This is usually done with a lumbar puncture. For information on how this procedure is performed, see spinal tap.

    The sample is sent to a laboratory, where a tiny amount is spread on a glass slide. A member of the laboratory team looks at the sample under a microscope. The smear shows the color of the fluid and the number and shape of cells present in the fluid. Other tests, such as a Gram stain, may be done to check for bacteria.

    How to Prepare for the Test

    For information on how to prepare for the procedure to obtain the CSF sample, see spinal tap.

    How the Test Will Feel

    The laboratory test is painless and does not involve you.

    For information on how it will feel to have a sample of CSF fluid removed, see spinal tap.

    Why the Test is Performed

    The test is done to check for signs of infection in a sample of CSF.

    What Abnormal Results Mean

    Bacteria or other germs in the sample may be a sign of:

    • Bacterial meningitis
    • Fungal infections
    • Tuberculosis

    Some bacteria or viruses can also be detected using special tests.

    Risks

    A laboratory smear poses no risk. For risks from the procedure done to get a CSF sample, see spinal tap.
