How is Bartter syndrome diagnosed?

Bartter syndrome is usually diagnosed after a combination of tests are performed on an individual with the signs and symptoms of the condition. Blood test results in an affected individual typically show low blood potassium levels (with normal blood pressure); low blood chloride levels; and an acid/base balance that is skewed towards the base (i.e. the blood is more alkaline than usual). High levels of the hormones renin and aldosterone in the blood would also support the diagnosis. Urine test results that would support the diagnosis include high levels of potassium and chloride, suggesting that the kidneys have impaired ability to control the concentrations of these electrolytes.[1] A positive genetic test result would confirm the diagnosis.
