BUN

Chloride

Creatinine

Glucose

Sodium

Potassium

Other Electrolytes (not in typical BMP)

Calcium & Magnesium

Ideal Body Weight (IBW)

Male IBW = 50 + (2.3 x inches over 5 feet in height)

Female IBW = 45.5 + (2.3 x inches over 5 feet in height)

Adjusted Body Weight

ABW = IBW + 0.4 (Actual – IBW)

use when total body weight is more than 120% IBW

Cockroft-Gault Creatinine Clearance

CrCl = (140-age) x (weight)   (x 0.85 if female)

            (SCr) (72)

Corrected Sodium

= Measured Sodium + [(Serum Glucose- 100)/100 x 1.6]

Corrected Calcium

= Measured Calcium + [0.8 x (4- Alb)]

Absolute Neutrophil Count (ANC)

ANC = WBC x (%Segs + % Bands)

100
