[Formula]
% Transferrin saturation
% Transferrin saturation = [Fe/(Fe+UIBC)] x 100
aka (serum iron/TIBC) x 100
[Formula]
Unconjugated/indirect bilirubin
Unconjugated bilirubin = Total bilirubin - direct (conjugated) bilirubin
[Formula]
LDL/Friedewald equation/non-HDL
LDL = Total Cholesterol - HDL - TG/5
[Formula]
A/G ratio
A/G ratio = albumin/ (total protein-albumin)
[Formula]
Timed Urine Calculations
GFR = urine creatinine x volume
______________________________
plasma creatinine x 1440
[Formula]
Beer’s Law
A = abc = log100/%T = 2-log%T
A = absorbance
a = absorptivity
b = light pattern
c = concentration of substance
%T = transmittance
[Formula]
Corrected WBC when >10 nRBCs present
Corrected WBC = uncorrected WBC x 100
___________________________
nRBCs + 100
[Formula]
Manual hemocytometer counts
Manual cell counts = # cells counted x dil x 10
___________________________
# squares
[Formula]
RBC indices
MCV = Hct/RBC x 10
MCH = Hgb/RBC x 10
MCHC = Hgb/Hct x 100
[Formula]
Absolute cell counts given relative values (WBC, reticulocytes)
Absolute WBC = total WBC x relative count (in decimal form)
