Cerebrospinal Fluid Control

Cerebrospinal fluid (CSF) analysis is a set of laboratory tests that examine a sample of the fluid surrounding the brain and spinal cord. This fluid is a clear and colorless ultrafiltrate of plasma. It contains glucose, electrolytes, amino acids, and other small molecules found in plasma. Under normal circumstances, CSF has very little protein and few cells. CSF protects the central nervous system from injury, cushions it from the surrounding bone structure, provides it with nutrients, and removes waste products by returning them to the blood. CSF is withdrawn from the subarachnoid space through a needle by a procedure called a lumbar puncture or spinal tap. CSF analysis includes tests in clinical chemistry, hematology, immunology, and microbiology.

Aalto’s CSF control is a stable liquid formulation made from human serum and other human and chemical components to mimic the characteristics of human spinal fluid. The material is available in two formulations:
