Donors at risk: impaired glucose tolerance

All potential living kidney donors should have a fasting plasma glucose level performed on at least two occasions. If the levels are: - >= 7 mmol/L on both occasions then the potential donor is diabetic and this is an absolute contraindication for living kidney donation, - 6.1-6.9 mmol/L on at least one occasion then this patient should have a 2 h oral glucose tolerance test (OGTT), - <6.1 mmol/L then this is normal and not a contraindication to donation. Patients at high risk for the development of type 2 diabetes mellitus (i.e. family history, age > 45 years, Aboriginal or Torres Strait Islander (ATSI) or obesity) should be screened with a 2 h OGTT. If the 2 h glucose of an OGTT results are: - >= 11.1 mmol/L then the patient is diabetic and this is an absolute contra-indication to living kidney donation, - 7.8-11.0 mmol/L then this patient has impaired glucose tolerance and this is an absolute contraindication to living kidney donation, - <7.8 mmol/L is normal and not a contraindication to donation. A past history of gestational diabetes is an absolute contraindication to living kidney donation.
