Cytology

fluids, no centrifugation is required. While relatively watery,
thin and hypocellular fluids smear is prepared from:
A *Centrifuged sediments*

6. If unstained slides are to be mailed, they must be placed in
the fixative for at least:
A. 5min.
B. *2 hours*
C. 1 hour
D. 1 day

7. For fluid cytology fluid has to be collected in:
A. *EDTA*
B. Sodium citrate
