Li et al reported equations for estimated glomerular filtration rate (GFR) in Chinese patients. The authors are from Third Xiangya Hospital, Central South University, Zinjiang Medical University, and Zhejiang University in China.
Patient selection: Chinese adult >= 18 years of age
Parameters:
(1) sex
(2) serum creatinine in µmol/L
(3) age in years
For males:
Parameter
Points
serum creatinine
2374.78 * ((creatinine) ^ (-0.54753))
age
(age) ^ (-0.25011)
eGFR in mL per mL per 1.73 square meter =
= PRODUCT(points for both parameters)
For females:
eGFR =
= (eGFR for male) * (0.8526126
Performance:
• 84% of results are within 30% of the measured GFR.
