Testing Schedule:
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:
3 hours (upon receipt in laboratory)
Comments:
Includes cell counts and total 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, eosinophils, lymphocytes, and a composite group of monocytes-histocytes-macrophages mesothelials. These slides are retained for approximately two months.
