Specimen(s):
CSF
Collection Medium:
CSF collection kit

WBC Normals 0-1 yrs 0-30/μL 1-5 yrs 0-20/μL 5-13 yrs 0-10/μL adult 0-5/μL
Comments:
Includes cell counts, total nucleated cells and RBC and nucleated cell differential if three or more cells are found. The differential is based on the morphologic examination of a wright-stained cytospin preparation. The cells are reported as number per μL; erythrocytes, total nucleated cells, neutrophils, lymphocytes, eosinophils, and a composite group of monocytes-histocytes- macrophages. These slides are retained for approximately two months.
