Exercise 45

The reference range for CSF protein is:

A. 6 to 8 g/dL

B. 15 to 45 g/dL

C. 6 to 8 mg/dL

D. 15 to 45 mg/dL

Step 1 of 2

CSF (cerebrospinal fluid) protein:

• Frequently performed chemical test on CSF is protein test

• Generally, CSF contains only small volume of protein

• Reference value for total CSF protein is 15 to 45 mg/dL (milligrams per deciliter)

Therefore, reference range for CSF protein is “15 to 45 mg/dL”. Hence, the correct answer is option.
