What this test is
The electrolyte panel measures levels of sodium, potassium, chloride, and bicarbonate (or total carbon dioxide) in the blood. It may also include calcium and other related substances depending on the lab. This panel is often part of a basic or comprehensive metabolic panel.
What it measures
- Sodium — reflects fluid balance and nerve function
- Potassium — reflects heart and muscle function
- Chloride — reflects fluid balance and acid-base status
- Bicarbonate — reflects the body's acid-base balance
- Calcium — reflects bone health and nerve function, if included
What the test involves
A healthcare professional collects a small sample of blood, usually from a vein in your arm, using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order an electrolyte panel to evaluate symptoms like weakness, confusion, irregular heartbeat, or swelling. It is also used to monitor conditions such as kidney disease, heart failure, or dehydration, and to check the effects of certain medications.
Preparation
Preparation instructions can vary, so follow the specific directions provided by the collection lab. In many cases, no special preparation is needed, but your clinician may ask you to fast or adjust medications.
How results are reported
Results are typically reported as numerical values for each electrolyte, along with a reference range. Reference ranges can differ between laboratories, so your results should be interpreted in the context of the lab that performed the test and your overall health.
