Quick Answer: What Are Normal Lumbar Puncture Results?

What is normal CSF cell count?

Normally, there are no RBCs in the cerebrospinal fluid, and there should be no more than five WBCs per cubic millimeter of CSF.

If your fluid contains RBCs, this may indicate bleeding.

It is also possible that you had a traumatic tap (blood leaked into the fluid sample during collection)..

How long will I be off work after a lumbar puncture?

Avoid strenuous activity for the first 24 hours after the procedure. You can return to all your usual activities such as work and driving, as soon as you feel well enough after that. Some of the test results from the lumbar puncture will take a few days, but others can take several weeks.

Can you walk after a lumbar puncture?

Avoid strenuous or vigorous exercise for a day or so following the lumbar puncture. If you have a headache, lay down as much as possible and drink plenty of fluids. Contact your health care provider if the headache persists.

What does high glucose in spinal fluid mean?

High CSF glucose levels 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. CSF glucose levels do not generally exceed 16.7 mmol/L (300 mg/dL).

What does blood in CSF indicate?

Red blood cell (RBC) count—normally no red blood cells are present in the CSF. The presence of red blood cells may indicate bleeding into the CSF or may indicate a “traumatic tap” – blood that leaked into the CSF sample during collection.

Is it normal to have lymphocytes in CSF?

Normal CSF contains a small number of lymphocytes and monocytes. The reference values are indicated in Table 6. The lymphocytes present in the CSF are similar to those in the peripheral blood. Small lymphocytes predominate, and 75 to 95% are T lymphocytes [31].

Why is protein increased in CSF in meningitis?

CSF protein Bacterial meningitis leads to a more permeable blood brain barrier (due to increased inflammation). Protein leaks into the subarachnoid space from the blood, resulting in markedly increased CSF protein levels.

How do you read lumbar puncture results?

Interpretation of CSF results from lumbar puncture (LP)Appearance: Clear.Opening pressure: 10-20 cmCSF.WBC count: 0-5 cells/µL. < 2 polymorphonucleocytes [PMN]) ... Glucose level: >60% of serum glucose.Protein level: < 45 mg/dL.Consider additional tests: CSF culture, others depending on clinical findings.

What level should a lumbar puncture be?

It is important to insert the spinal needle below the conus medullaris at the L3/L4 or L4/L5 interspinous levels. With growth of the spine, the conus typically reaches the adult level (L1) by 2 years of age.

What is considered high protein in CSF?

CSF protein levels of at least 150 mg per dL (1.5 g per L)—as seen in many infectious and inflammatory conditions, or as a result of a traumatic tap that contains more than 100,000 RBCs per mm3—also will result in xanthochromia.

What are the risks of a lumbar puncture?

RisksPost-lumbar puncture headache. Around 25% of people who have undergone a lumbar puncture develop a headache afterward due to a leak of fluid into nearby tissues. … Back discomfort or pain. You may feel pain or tenderness in your lower back after the procedure. … Bleeding. … Brainstem herniation.

Does high protein in CSF mean MS?

Cerebral Spinal Fluid Studies Oligoclonal Immunoglobulin Bands can be identified in the CSF of MS patients via electrophoresis. The overall protein level is also slightly elevated – up to 0.1 g/L. Protein level can be higher if the patient is going through a marked relapse (i.e.,. severe optic neuritis).

What diseases can be found in spinal fluid?

A CSF analysis may include tests to diagnose:Infectious diseases of the brain and spinal cord, including meningitis and encephalitis. … Autoimmune disorders, such as Guillain-Barré Syndrome and multiple sclerosis (MS). … Bleeding in the brain.Brain tumors.

What is the best position after lumbar puncture?

As blood will distribute into the epidural space through few spinal segments superiorly and inferiorly, it is not essential to introduce it into the exact place at which the dural puncture was performed. After the procedure, the patient is asked to lie still for 1–2 h in a supine position and is then mobilised.

How do you check for a CSF leak at home?

A pledget study involves placing small cotton pads (called “pledgets”) into the nose. This test is used to confirm the presence of a CSF leak, although it cannot determine the exact location of the leak. To determine the exact location of the leak, a CT cisternogram would be performed.
