Metabolic / Electrolytes
Also known as: Na, Serum Sodium, Blood Sodium
Seek immediate medical attention if you experience severe symptoms like confusion, seizures, extreme weakness, or loss of consciousness, as these can be signs of very low or very high sodium levels.
This test checks how much sodium is in your blood. Sodium is a key mineral. It helps your body's cells do their jobs well. It is important for keeping fluids balanced. It also helps your nerves and muscles work right.
Doctors often order this test to see how much water and important salts are in your body. They might do this if you have puffy areas, are very thirsty, or have issues with your kidneys or heart.
Reference ranges for sodium can vary slightly depending on the laboratory that performs the test. Your doctor will interpret your results based on the specific ranges used by their lab.
