@75_saa: Cerebrospinal Fluid (CSF) collection - a vital procedure done through a lumbar puncture to analyze brain and spinal health. This clear fluid gives doctors key insights into infections, bleeding, and neurological disorders. CSF (Cerebrospinal fluid) collection is a medical test where a small amount of the fluid surrounding the brain and spinal cord is removed for analysis. The most common method is a lumbar puncture (spinal tap), performed by inserting a needle into the lower back to extract the fluid. This helps diagnose conditions like infections, autoimmune disorders, bleeding, and tumors in the central nervous system. . . #sciencestudent #study #knowledge #medical #usa
