  2. Lumbar puncture - Wikipedia

    en.wikipedia.org/wiki/Lumbar_puncture

    Illustration depicting lumbar puncture (spinal tap) Spinal needles used in lumbar puncture Illustration depicting common positions for lumbar puncture procedure. The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the ...

  3. Intracranial pressure - Wikipedia

    en.wikipedia.org/wiki/Intracranial_pressure

    More commonly, decreased ICP is the result of lumbar puncture or other medical procedure involving the spinal cord. Various medical imaging technologies exist to assist in identifying the cause of decreased ICP. Often, the syndrome is self-limiting, especially if it is the result of a medical procedure. [citation needed]

  4. CSF tap test - Wikipedia

    en.wikipedia.org/wiki/CSF_tap_test

    The CSF tap test, sometimes lumbar tap test or Miller Fisher Test, is a medical test that is used to decide whether shunting of cerebrospinal fluid (CSF) would be helpful in a patient with suspected normal pressure hydrocephalus (NPH).

  5. Oligoclonal band - Wikipedia

    en.wikipedia.org/wiki/Oligoclonal_band

    For the analysis of cerebrospinal fluid, a sample is first collected via lumbar puncture (LP). Normally it is assumed that all the proteins that appear in the CSF, but are not present in the serum, are produced intrathecally (inside the central nervous system). Therefore, it is normal to subtract bands in serum from bands in CSF when ...

  6. CSF glucose - Wikipedia

    en.wikipedia.org/wiki/CSF_glucose

    In addition, damage to small blood vessels during lumbar puncture (traumatic tap) can lead to an increased CSF glucose since the blood that enters the collected CSF sample contains higher levels of glucose. [4] CSF glucose levels do not generally exceed 16.7 mmol/L (300 mg/dL). [3]

  8. Queckenstedt's maneuver - Wikipedia

    en.wikipedia.org/wiki/Queckenstedt's_maneuver

    Given normal anatomy, the intracranial pressure will be reflected as a rapidly rising pressure measured from the lumbar needle, within 10–12 seconds. If there is a stenosis in the spine, there will be a damped, delayed response in the lumbar pressure, thus a positive Queckenstedt's maneuver.

  9. Pandy's test - Wikipedia

    en.wikipedia.org/wiki/Pandy's_test

    One drop of CSF sample (collected from the patient by lumbar puncture technique), is added to about 1ml of Pandy's solution. The turbid appearance signifies the presence of elevated levels of globulin protein in the CSF and is regarded as positive Pandy's reaction.
