biliary drainage are not acceptable specimens.
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.
Methodology:
Count and Wright Stain
Instructions:
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.
