Formulas Used:
Creatinine Clearance (CrCl):
Adult Males = [(140 - age in years) x (weight in kg)] ÷ 72 x serum Cr
Adult Females = 0.85 x [((140 - age in years) x (weight in kg)) ÷ 72 x serum Cr]
eGFR per CKD-EPI= 141 x min(Cr/k, 1)a x max(Cr/k, 1)-1.209 x 0.993age x 1.018[if female] x 1.159[if black/African American]
k = 0.7 for females; 0.9 for males
a = -0.329 for females; -0.411 for males, min indicates the minimum of Cr/k or 1, and max indicates the maximum of Cr/k or 1
eGFR per MDRD4= 186 x creatinine-1.153 x age-0.203 x (0.742 if female) x (1.212 if black/African American)
eGFr per MDRD6 = 170 × (serum Cr)-0.999 × age-0.176 × (BUN)-0.17 × albumin0.318 × 0.762[if female] × 1.18[if African American]
