55
[Formula] % Transferrin saturation
% Transferrin saturation = [Fe/(Fe+UIBC)] x 100 aka (serum iron/TIBC) x 100
56
[Formula] Unconjugated/indirect bilirubin
Unconjugated bilirubin = Total bilirubin - direct (conjugated) bilirubin
57
[Formula] LDL/Friedewald equation/non-HDL
LDL = Total Cholesterol - HDL - TG/5
58
[Formula] A/G ratio
A/G ratio = albumin/ (total protein-albumin)
59
[Formula] Timed Urine Calculations
GFR = urine creatinine x volume ______________________________ plasma creatinine x 1440
60
[Formula] Beer’s Law
A = abc = log100/%T = 2-log%T A = absorbance a = absorptivity b = light pattern c = concentration of substance %T = transmittance
61
[Formula] Corrected WBC when >10 nRBCs present
Corrected WBC = uncorrected WBC x 100 ___________________________ nRBCs + 100
62
[Formula] Manual hemocytometer counts
Manual cell counts = # cells counted x dil x 10 ___________________________ # squares
63
[Formula] RBC indices
MCV = Hct/RBC x 10 MCH = Hgb/RBC x 10 MCHC = Hgb/Hct x 100
64
[Formula] Absolute cell counts given relative values (WBC, reticulocytes)
Absolute WBC = total WBC x relative count (in decimal form)
