what the risks are --> csf protein test, csf total protein, protein in cerebrospinal fluid, csf, csf, clear fluid that circulates, in the space surrounding the spinal cord, an abnormal protein level, in the csf suggests that there, abnormal process occurring, in the central nervous system, a sample of csf is obtained, by lumbar puncture, spinal tap, cerebrospinal fluid is then analyzed, in the lab, patients, either sit up, lie down on sides, the back parallel, bed, chin tucked under, legs curled, in the fetal position, healthcare provider, use the bony protrusions, the hip, the most appropriate location to remove fluid, at what is known, the l3-l4 vertebral level, subsequently iodine, clean off the area, a sterile sheet, draped over the surrounding area, in infants, small children, emla cream, a local anesthetic cream, numb the skin, applied, 1 hour, in adults, lidocaine, injected under the skin initially, deeper such that tissue beneath the skin, numbed, a thin 20-gauge needle, inserted, interspace between the vertebra, depending on how much subcutaneous tissue there, require shallow, deeper penetration, the needle, an audible "pop", the needle penetrates the dura, membrane that surrounds the spinal cord, encases the fluid, fluid flowing out, the needle, collected in plastic containers, under normal circumstances, opening pressure, measured, a manometer, 20-30 cc of spinal fluid, collected, sent, evaluation under the microscope, under experienced hands there should not be any pain, a feeling of pressure, the needle is inserted but, appropriate anesthetic, should not hurt, feel numbness shooting down the leg, due to irritation of a nerve root, needle is withdrawn, sensation subsides, not permanent, following the procedure, patient is advised to remain lying down, an hour, two, prevent low-pressure headaches, entire procedure takes approximately 20 minutes, csf total protein count helpful in diagnosing tumors, infection, polyneuritis, inflammation of several groups of nerve cells, vasculitis, blood, in the csf, trauma, normal protein range is 15 to 45 mg/dl, mg/dl = milligrams per deciliter, the protein level increases considerably, tumors, hemorrhage, polyneuritis, trauma, blood, in the csf, protein level decreases, indicate rapid csf production, additional conditions under which the test performed, chronic inflammatory polyneuropathy, primary lymphoma, the brain, hemorrhage, intracerebral, deep, hemorrhage, intracerebral, hypertensive, hemorrhage, intracerebral, lobar, hemorrhage, intracerebral, hemorrhage, subarachnoid, csf protein levels must be interpreted, in the context of clinical findings, results of other laboratory tests, a diagnosis, risks of lumbar puncture, hypersensitivity, allergic, reaction, anesthetic, discomfort, headache, bleeding, spinal canal, infection, brain herniation, performed on a person, increased intracranial pressure, resulting in brain damage, death, test is not performed on anyone, clinical signs, imaging suggestive of increased intracranial pressure, transient leg numbness, tingling, due to irritation of a nerve root by the needle.
