ASCP Reference Ranges and Equations Flashcards
% transferrin saturation calculation
serum iron/TIBC x 100
UIBC calculation
TIBC - serum iron
TIBC calculation
Serum iron + UIBC
Unconjugated Bilirubin calculation
total bilirubin - direct bilirubin
LDL calculation/Friedewald
total cholesterol - HDL - triglycerides/5
A/G Ratio
total protein- albumin = globulin
Timed urine Calculations
?
Creatinine clearance calculation
U/P X V/min X 1.73/BSA
U = urine creatinine
P = plasma creatinine
V = volume/min
BSA = pt body surface area
Beers law calculation
corrected wbc counts
and corrected wbc count when >10nrbc present
wbc x 100/ nrbc +100
Manual hemocytometer counts
got this
MCH
HGB/RBC X 10
MCV
