The protein content of the cerebrospinal fluid in newborns is between 0.2 and 1.2 g/L. If the child’s normal protein value is within this range, the protein content is normal. If a child has significantly higher protein, consider having septic meningitis. If a child has septic meningitis, there is not only an increase in the amount of cerebrospinal fluid protein, but also a decrease in sugars, and pictures of the cerebrospinal fluid can be done on the child and the causative organisms can be found. Therefore, a test of cerebrospinal fluid proteins in a child is of great clinical importance to determine the exact nature of the infection in the central nervous system. If a child’s protein level is normal or significantly low, it is often due to viral meningitis, and septic meningitis can basically be ruled out.
