Fluid balance tests can be used to diagnose various inflammatory diseases. Take a closer look at the subtests and read about what potassium and sodium levels refer to.
Name and abbreviation of the test: POTASSIUM P-K
In addition to sodium, potassium is an important salt in the blood. Certain diuretics, vomiting and diarrhoea may lower potassium levels. Elevated levels of potassium may indicate kidney failure. It is also known that certain diuretics cause an increase in potassium levels. Potassium reference values in the test are 3.3–4.8 mmol/l.
Name and abbreviation of the test: SODIUM P-NA
Sodium is one of the most important minerals in body fluids. Appropriate sodium levels in blood and other fluids are essential for a functioning metabolism. The sodium levels may also change due to certain diseases or medications. Prolonged vomiting and diarrhoea can also cause sodium loss. The reference values for sodium are 137–144 mmol/l.
