Potassium (K) In Blood: Why It Is Done
Content provided by Healthwise
Why It Is Done
A blood test to check potassium is done to:
- Check levels in people being treated with medicines such as diuretics and for people having kidney dialysis.
- Check to see whether treatment for too low or too high potassium levels is working.
- Check people with high blood pressure who may have a problem with their kidneys or adrenal glands.
- Check the effects of extra nutrition (total parenteral nutrition [TPN]) on potassium levels.
- Check to see whether certain cancer treatments are causing too many cells to be destroyed (cell lysis). Cell lysis syndrome causes very high levels of some electrolytes, including potassium.
