Kidney failure occurs when the kidneys lose their ability to filter waste from the blood. There are currently three main ways to evaluate kidney health for diagnosis, notes Dr. Julio César Arriaga García Rendón, nephrology specialist at ABC Medical Center.
The first step is usually blood testing, which helps doctors assess kidney function based on the levels of minerals and other substances in the body that the kidneys may not be processing correctly.
A second method involves urine testing. One of the kidneys’ main functions is producing urine, which should be the right amount and of proper quality. Checking both of these factors helps provide a clearer picture of kidney health.
Imaging studies, meanwhile, allow doctors to capture images and videos of the kidneys. This method creates a visual record that helps assess the kidneys’ structure and size, whether there are any abnormalities in their contour or internal structure, and other details.
More specialized tests can also measure how much blood these organs receive, or assess whether kidney pressure is at an appropriate level.
Once one or more of these tests have been performed, the doctor can determine the kidneys’ current state, Dr. Arriaga notes.
Stages of Kidney Failure
Stages 1 and 2 are considered stages of good kidney function, during which you can take preventive steps to protect kidney health.
Stages 3, 4, and 5 mark a shift into a higher-risk phase and are classified as chronic kidney disease. Proper care can help you avoid reaching this stage.
