Why Lab Testing is Essential for Kidney Disorders
Laboratory tests are fundamental for diagnosing kidney disorders, monitoring kidney function, and detecting complications. Blood and urine tests can reveal electrolyte imbalances, protein abnormalities, and filtration problems that indicate kidney dysfunction before symptoms become severe.
Other Relevant Tests
Chloride
This test measures chloride levels in the blood, which can be disrupted by kidney disorders. Both chronic kidney disease and acute kidney injury can cause chloride imbalances, with levels being either elevated or decreased depending on the type and severity of the kidney condition.
