Stage 1 of Chronic Kidney Disease
A person with stage 1 chronic kidney disease (CKD) has kidney damage with a glomerular filtration rate (GFR) at a normal or high level greater than 90 ml/min. There are usually no symptoms to indicate the kidneys are damaged. Because kidneys do a good job even when they’re not functioning at 100 percent, most people will not know they have stage 1 CKD. If they do find out they’re in stage 1, it’s usually because they were being tested for another condition such as diabetes or high blood pressure (the two leading causes of kidney disease).
Symptoms of stage 1 kidney disease
Other ways a person may discover they are in stage 1 CKD include:
- Higher than normal levels of creatinine or urea in the blood
- Blood or protein in the urine
- Evidence of kidney damage in an MRI, CT scan, ultrasound or contrast X-ray
- A family history of polycystic kidney disease (PKD)
