Body Fluid Cell Count and Differential
|Epic Lab Code:||LAB1017|
|Downtime Form:||A-1a General Laboratory Requisition|
Miscellaneous Body Fluids
|Lavender top tube 3 mL (EDTA)||Miscellaneous container; contact laboratory|
Galeal, cyst fluids, pus from abscesses and biliary drainage are not acceptable specimens.
Synovial fluid specimens must be sent in an EDTA tube (lavender top) since they often clot. Samples should be received in the laboratory within four hours of collection.
24 hrs/day, 7 days a week, including holidays.
Turn Around Time:

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.
