Potassium RBC Test - More Information
The potassium RBC test, also known as an intracellular potassium RBC blood test and a potassium RBC lab test, helps assess intracellular potassium RBC blood levels.
Potassium RBC testing is a useful way to measure the potassium levels inside RBC cells. In contrast to the potassium blood test which measures blood potassium levels at a point in time, the potassium RBC test helps evaluate longer term potassium stores in the body.
To get a potassium RBC test near you, order online and get your blood drawn at the selected Quest Diagnostics lab. Once the potassium RBC lab report is ready, it will be available for download. As can be seen on the sample potassium RBC lab report, the potassium RBC level is reported as a number and can be compared against the reference range provided by the lab. No fasting is recommended before this intracellular potassium RBC test.
