Estimate kidney function (GFR)
Kidney function (estimated GFR [glomerular filtration rate]) is calculated based on serum creatinine levels and age.
All diseases related to lifestyle-related diseases are associated with chronic kidney disease. Please use this information for the “early detection and early treatment” of kidney disease.
* CKD severity classification is determined based on the underlying disease, GFR category, and urine protein category. (Revised in 2012)

・“Chronic kidney disease (CKD)” is defined as the presence of findings indicating kidney disease, such as proteinuria, or a GFR (glomerular filtration rate) below 60 that persists for three months or longer.
・CKD severity classification is determined based on the underlying disease, GFR category, and urine protein category. (Revised in 2012)
Notation example: Diabetes G3aA2
・When urine protein is tested using test strips, the urine protein categories are: A1: (–, –+), A2: (+), A3: (2+ or higher)
・The GFR estimation formula is the one used by the Japanese Society of Nephrology.
<GFR Estimation Formula> (For adults) GFR (male) = 194 * Scr-1.094 * age-0.287; GFR (female) = GFR (male) * 0.739
