Estimated glomerular filtration rate (eGFR) result code N[A]

Guide for use:

CODE 1 Kidney function stage 1

Use this code when the estimated glomerular filtration rate (eGFR) is greater than or equal to 90 (ml/min/1.73m²).

CODE 2 Kidney function stage 2

Use this code when the estimated glomerular filtration rate (eGFR) is greater than or equal to 60 but less than 90 (ml/min/1.73m²).

CODE 3a Kidney function stage 3a

Use this code when the estimated glomerular filtration rate (eGFR) is greater than or equal to 45 but less than 60 (ml/min/1.73m²).

CODE 3a Kidney function stage 3b

Use this code when the estimated glomerular filtration rate (eGFR) is greater than or equal to 30 but less than 45 (ml/min/1.73m²).

CODE 4 Kidney function stage 4

Use this code when the estimated glomerular filtration rate (eGFR) is greater than or equal to 15 but less than 30 (ml/min/1.73m²).

CODE 5 Kidney function stage 5

Use this code when the estimated glomerular filtration rate (eGFR) is less than 15 (ml/min/1.73m²).

Comments:

The estimated glomerular filtration rate (eGFR) is a measure of the amount of fluid that passes through the kidneys per unit time.
