This model is intended for adult individuals considering living kidney donation. It provides a predicted 6-month post-donation serum creatinine and an expected eGFR calculated based on the predicted serum creatinine using the race-free creatinine-based equation (CKD-EPI 2021).

The population used for this study included adult (≥18-year-old) living kidney donors who donated a kidney between January 2005 and June 2019 in the United States. The 6-month post-donation serum creatinine was modeled using multivariable linear regression.

Consider applying this calculator to inform the living kidney donor candidate of her/his individualized predicted 6-month post-donation kidney function. Post-donation kidney function varies by individual characteristics. The decision-making to accept or decline a donor candidate should engage donor-provider discussions considering living kidney donation risks and benefits per individual case.
