Guideline recommendations for GFR assessment in living kidney donor candidates
| Guideline | GFR assessment | GFR-based criteria |
| British Transplantation Society (2018) (52) | mGFR in everyone after initial screening using eGFR | Provides age and sex-specific GFR criteria |
| KDIGO (2017) (11,12) | eGFR, followed by confirmation with mGFR, CrCl or eGFR | Donor candidates with GFR ≥90 ml/min per 1.73m2 should be considered acceptable, and those with GFR ≤60 ml/min per 1.73m2 should be excluded Decision to approve donor candidates with GFR 60–89 ml/min per 1.73m2 should be individualized on the basis of demographic and health profile in relation to the transplant program’s acceptable risk threshold |
| OPTN (2021) (47) | mGFR or 24-hour CrCl | No specific recommendations provided |
| Canadian KPD Protocol (2015) (54) | eGFR on two separate occasions, followed by 24-hour CrCl on two separate occasions or mGFR | Provides age-specific criteria |
| ERBP (2013) (53) | eGFR; mGFR when more exact knowledge of GFR is needed or where is doubt regarding the accuracy of eGFR | Recommends age-dependent GFR cutoffs, such that the GFR of the remaining kidney will be >37.5 ml/min per 1.73m2 at the time the donor reaches age 80 |
| CARI (2010) (61) | eGFR, at least on two separate occasions or CrCl; mGFR if there is doubt regarding the accuracy or eGFR or CrCl | Recommends against accepting kidneys from donors with GFR <80ml/min per 1.73m2 |
| Amsterdam forum (2005) (62) | eGFR or CrCl; mGFR may be used in patients with borderline GFR determination | GFR <80 ml/min per 1.73m2 or body-surface area-adjusted GFR <2 SD below normal on the basis of age and sex generally preclude donation Additionally noted successful transplantation from some, usually elderly living donors with GFR as low as 65–70 ml/min per 1.73m2, indicating a need for individualization in donors with GFR <80 ml/min per 1.73m2 |
