This is an updated guideline from Nice on anaemia in chronic kidney disease. The main changes relevant for us are the tests which should be used to diagnose it and the targets for treatment.
This guideline seems to be for any patient with CKD and GFR less than 60. I am not covering children, patients on erythropoietic stimulating agent (ESA) therapy or patients on dialysis in this summary as their care is generally managed in hospital, but they are covered in the guideline.
If the GFR is over 60, anaemia is unlikely to be due to CKD.
