Stage 1 chronic kidney disease (CKD) is defined by a glomerular filtration rate of 90 or more (GFR is the estimate of kidney function, and its normal value for adults is around 90 or more). However, there is abnormal protein excretion in the urine in stage 1 of CKD. Usually, there are no specific symptoms of stage 1 CKD other than foamy urine due to protein in the urine (26).
