eGFR Formulas using CKD-EPI equation

For adults (age >=18 years)

African American Female

If serum creatinine (Scr) <= 0.7

eGFR = 166 x (SCr/0.7) ^-0.329 x 0.993^Age

If serum creatinine (Scr) > 0.7

eGFR = 166 x (SCr/0.7) ^-1.209 x 0.993 ^Age

African American Male

If serum creatinine (Scr) <= 0.9

eGFR = 163 x (SCr/0.9) ^-0.411 x 0.993 ^Age

If serum creatinine (Scr) > 0.9

eGFR = 163 x (SCr/0.9) ^-1.209 x 0.993 ^Age

Non-African American Female

If serum creatinine (Scr) <= 0.7

eGFR = 144 x (SCr/0.7) ^-0.329 x 0.993 ^Age

If serum creatinine (Scr) > 0.7

eGFR = 144 x (SCr/0.7) ^-1.209 x 0.993 ^Age

Non-African American Male

If serum creatinine (Scr) <= 0.9

eGFR = 141 x (SCr/0.9) ^-0.411 x 0.993 ^Age

If serum creatinine (Scr) > 0.9

eGFR = 141 x (SCr/0.9) ^-1.209 x 0.993 ^Age
