1. Patient A, 45 years old , white male , SCr-2 mg/dl , height - 172.2cm , weight -50kg
Cockcroft gault formula - (140-age ) × body weight ÷ serum creatinine clearance × 72
= (140-45) × 50 / 2 × 72
= 95×50/ 2×72
= 32.8
BSA = √ weight in kg × height in cm /3600
= √ 50× 172.2 /3600
= 1.5m square
2. Patient B ,45years , white male , serum creatinine 2 mg/dl , weight -75kg ,height - 172.2cm
Cockcroft gault formula - (140-age ) × body weight ÷ serum creatinine clearance × 72
= (140-45) × 75/ 2×72
= 49.4
BSA - √ weight in kg × height in cm /3600
= √ 75× 172.2/3600
= 1.8m square
3. atient A, 45 years old , white male , SCr-2 mg/dl , height - 172.2cm , weight -100kg
Cockcroft gault formula - (140-age ) × body weight ÷ serum creatinine clearance × 72
= (140-45) × 100/ 2 × 72
= 65.9
BSA - √ weight in kg × height in cm /3600
= √ 100× 172.2/3600
= 2.1m square
