A sodium test checks for how much sodium is in the blood. Sodium helps the body keep the right mix of water and minerals.
This test is usually done to check the water and electrolyte balance of the body.
In general, there's nothing you have to do before this test, unless your doctor tells you to.
A health professional uses a needle to take a blood sample, usually from the arm.
The test will take a few minutes.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor or nurse call line if you are having problems. It's also a good idea to keep a list of the medicines you take. Ask your doctor when you can expect to have your test results.
