Sodium Test

A sodium test is a laboratory test that measures the level of sodium in the blood. Sodium is an electrolyte that plays a crucial role in maintaining the balance of fluids in the body and in regulating the function of muscles and nerves.

Pre-test preparation: No special preparation is typically required for a sodium test.

Testing method: A small sample of blood is taken from a vein in the arm and sent to a laboratory for analysis. The sample is usually analyzed using a device called an electrolyte analyzer.

Common symptoms for prescribing this test: A sodium test may be ordered if a person has symptoms of a condition that affects the level of sodium in the blood, such as dehydration, kidney disease, or certain types of heart and lung disorders. It can also be used as a part of routine lab work to check overall health status.

Diagnosis: The results of a sodium test are used to help diagnose and monitor a variety of conditions, including dehydration, kidney disease, and certain types of heart and lung disorders. Elevated levels of sodium can indicate dehydration, while low levels can indicate kidney disease, certain types of heart and lung disorders, or the use of certain medications.

Reference range: The reference range for sodium levels varies depending on the lab and the population being tested, but generally, a normal range is 135 to 145 mEq/L.

Normal values: Sodium levels are normally between 135 to 145 mEq/L.
