To Know the Basics About Kidney Health / Diagnosis of CKD / Additional Diagnostic Tools for CKD

Blood Tests

Estimated Glomerular Filtration Rate (eGFR)

A doctor will calculate your GFR using results from a blood test as well as additional factors like age, sex and ethnic background. This will tell the doctor how much blood your body will filter per minute. It is the best way to measure kidney function and the presence of CKD.

• Healthy levels are approximately 90mL/min (60 to 120)
• Kidney disease levels are less than 60mL/min
• Kidney failure levels are 15mL/min >
• Kidney failure levels are less than 15mL/min
• Your results will be classified into 5 stages which inform your level of CKD and how your doctor will tailor your treatment

Blood Test for Creatinine

Determines if there is too much creatinine (a waste product) in the blood. High levels of creatinine in the blood usually indicate kidney malfunction/disease.

Kidney Biopsy

Biopsy of the Kidney

• The doctor will remove a small tissue sample of the kidney and analyze it under a microscope for any signs of kidney damage and other criteria

Imaging Tests

CT Scan

Produces a visualization of the size and structure of your kidneys and urinary tract to potentially see any problems, like size differences.

• This can denote size differences (i.e. kidney stones or tumours).
• Ultrasounds and MRIs can also help detect any blockages in the kidneys or between the kidney and any other organs

Screening Tests

You may be screened for family history (kidney disease – primary relative like parent or sibling), history of high blood pressure, if you’ve taken any medications that may affect your kidney functioning, changes in urinary habits, etc.
