Comments:
The Hematology Laboratory will make and review a smear if any of the following conditions apply: (1) patient's first CBC sample AND results meet laboratory review criteria; (2) questionable (not necessarily abnormal) CBC results; (3) CBC results are significantly different from that of a previous specimen; (4) a physician specifically requests a smear review by Technologist or a "Pathologist Review Blood Smear". EDTA samples are saved in the laboratory until 4:00 p.m. the day after receipt. Upon request, a smear could be made up until that time if necessary. However, as the specimen ages, cell disintegration and distortion may occur. Stained smears are held in the laboratories for approximately two months.
Methodology:
Flow Cytometry hgb = Colorimetric
