Sodium

What is being analysed?

Sodium is being analysed here. Sodium is an electrolyte found in the blood and is important for balancing fluids and acids in the body. The sodium blood test measures the amount of sodium in the blood.

What does the result mean?

Normal sodium levels in the blood range from 135 to 145 milliequivalents per liter (mEq/L).

Why is it performed?

The sodium blood test is used to evaluate kidney function, different hormones that regulate it, and situations of fluid regulation in the human body. It is usually evaluated together with the urine sodium analysis to provide more information. In addition, it allows the evaluation of the different hormones that control it and the correct regulation of fluids in the human body.

When should sodium levels be analysed?

The sodium blood test is a routine test that can be used to check your overall health. It can help monitor problems that affect the balance of fluids, electrolytes, and acidity in the body. The test is usually part of a group of tests called an ionogram. It can also be part of two other groups of tests called basic metabolic panel and complete metabolic panel.

What sample is required?

The sample required for the sodium blood test is a blood sample.

Is any prior preparation required?

No preparation is required for the sodium blood test.

What are considered to be normal values?

Normal sodium levels in the blood range from 135 to 145 milliequivalents per liter (mEq/L). If sodium levels in the blood are too high or low, that can indicate a problem with the kidneys, dehydration, or another type of medical problem. Symptoms of high blood sodium levels (hypernatremia) include: excessive thirst, infrequent urination, vomiting, diarrhoea, confusion, muscle spasms, and seizures. Symptoms of having low blood sodium levels (hyponatremia) include: weakness, tiredness, confusion, muscle fasciculations (small, involuntary muscle contractions), and seizures.
