The Purpose of a Sodium Test
Sodium in your food adds flavor, but sodium in your body adds balance — it’s an electrolyte that controls fluid and pH levels for optimal health. Sodium (aka the chemical symbol Na) can be tested as part of your annual blood work, or it may need to be checked if you have symptoms caused by high sodium levels (hypernatremia) or low (hyponatremia). For instance, low sodium can cause leg cramps and disrupt normal muscle and nerve function, while high sodium can elevate your blood pressure.
What Does the Blood Test for Na Measure?
The sodium test will tell you how much sodium is in your body.
Who Should Take a Sodium Level Test?
Confusion, muscle twitches, and seizures are signs that your sodium is either too high or too low, and can signal the need for a Na lab test. You may also monitor your levels if you have high blood pressure or a kidney disorder, which can be affected by the amount of sodium in your body. And you can preventively measure your levels during your annual checkup; sodium can be tested on its own or included in an electrolyte panel, basic metabolic panel, or comprehensive metabolic panel.
Sodium Lab Test Preparation
You don’t need to take any special steps before your blood test for Na.
Na Lab Test Results
The typical ideal range for sodium is 135 to 145 milliequivalents per liter. If your levels fall outside that range, you may need more testing to determine an appropriate course of treatment.
