What Is Sodium Test?
Sodium, chemically represented as Na+ is an essential mineral that plays many vital roles in our body such as:
- Act as a major cation in the ECF (extracellular fluid) contributing to the ECF compartment volume and osmotic pressure.
- Regulation of blood volume.
- Regulation of blood pressure.
- Help in generation of action potential and nerve impulse conduction.
- Key electrolyte in normal functioning of nerves.
- Help in proper functioning of muscles.
- Acid-base balance etc.
Usually, sodium is maintained in our body in a narrow range (135-145 mmol/L). Extra sodium is excreted via urine. If sodium level increases (Hypernatremia) or decreases (Hyponatremia) in your body, it produces a variety of symptoms and signs.
Sodium test is used to measure sodium levels in your body. Usually, serum sodium is evaluated for a number of indications. However, urine sodium level can also be evaluated.
Sodium test is a routine test used for screening, diagnosis or monitoring of many diseases, disorders and conditions that manifest as either hyponatremia or hypernatremia.
Why Do I Need a Sodium Test?
Your health care provider may order a serum sodium test if you have symptoms or signs suggesting hyponatremia or hypernatremia such as:
Features of hyponatremia:
- Headache
- Nausea
- Vomiting
- Fatigue
- Irritability
- Lethargy
- Reduced attention
- Weakness
- Muscle cramps/spasms
- Altered consciousness
- Confusion
- Seizures
- Impaired cognition
- Abnormal gait
- Increased falls.
Features of hypernatremia:
- Increased thirst
- Anorexia
- Nausea
- Vomiting
- Weakness
- Muscle twitching
- Confusion
- Seizures.
Monitoring purpose:
- Pre-operative evaluation.
- Post-operative evaluation.
- Burn patients.
- Intake of certain drugs such as anti-psychotics & mood stabilizers that affect the level of blood sodium.
- To check the effectiveness of treatment in case of hyponatremia or hypernatremia.
How Do I Prepare for Sodium Test?
Follow these simple steps if you are planning for a sodium test:
- Take an appointment: Fix an appointment for sodium test in a diagnostic lab to avoid waiting at the time of test.
- Food: You can take your usual meals a night before the test.
- Fasting: 8-9 hours fasting is usually required for sodium test. You can drink water during the fasting period.

- Exercise: Avoid strenuous exercise before the test as it may alter test results.
- Smoking: Avoid smoking before the test as it may affect the test results.
What Is the Procedure for Sodium Test?
The procedure of sodium test includes the following steps:
- If blood sample is required:
- First a torniquet will be tied around your arm.
- Then a cotton swab soaked with 70% alcohol is used to clean/disinfect the injection site before needle insertion.
- Then a small needle will be inserted in the vein of your arm and required amount of blood is withdrawn from it and collected in a test tube.
- Then the needle is removed and an adhesive sticker is placed on the puncture site to prevent it from infections.
