Sodium Test: Price, Procedure, Preparation & Normal Range
A sodium blood test measures the amount of sodium in the blood. Sodium is an essential electrolyte that helps regulate the balance of fluids in the body, transmit nerve impulses, and support muscle function. The test is typically ordered as part of a routine electrolyte panel, which may also include tests for potassium, chloride, and bicarbonate.
If your sodium blood test results are abnormal, your healthcare provider may recommend additional tests or treatments to determine the underlying cause and address any imbalances. It’s important to follow your healthcare provider’s recommendations and discuss any questions or concerns you may have about your test results. The price range of sodium test is between Rs 90 to Rs 252.
Your doctor may recommend a Sodium test because of the following symptoms-
- Unexplained swelling, particularly in the feet or ankles
- Changes in urination, such as increased or decreased frequency or volume
- Nausea or vomiting
- Dizziness or lightheadedness
- Muscle weakness or cramping
- Fatigue or lethargy

Purpose
A sodium test can be used to help diagnose and monitor various conditions, such as:
- Dehydration or fluid imbalances
- Kidney disease
- High blood pressure
- Heart failure
- Liver disease
- Hormonal imbalances, such as adrenal gland disorders
- Medications or medical treatments that can affect sodium levels
Preparation
- In general, fasting is not required for a sodium blood test. However, your healthcare provider may advise you to avoid eating or drinking for a certain period of time before the test if other tests are being performed at the same time that require fasting.
- Inform your healthcare provider about any medications or supplements you are taking, as some medications can affect sodium levels in the blood.
- You may need to temporarily discontinue certain medications prior to the test, but do not stop taking any medications without consulting your healthcare provider.
- Wear comfortable, loose-fitting clothing that allows easy access to your arm for the blood draw.
Procedure
t is a fairly simple diagnostic blood test. Below are the steps to draw a blood sample from the vein in your arm or hand-
- A technician (phlebotomist) may tie a tourniquet (elastic band) to your arm.
- The phlebotomist will locate your blood vessel.
- Then the site is cleaned with spirit.
- A Needle is inserted into your vein to draw the blood.
- The blood sample is then withdrawn into a syringe or a vial.
- Cotton is placed on the puncture site with mild pressure till the bleeding stops.
- A small band-aid is then placed, which may be removed after an hour.
The entire procedure takes only a few minutes.
Risk
It is a very simple and safe test. The risks involved are the same as that of any other blood test. These include-
- Infection at the puncture site if proper sterilization protocol is not followed and the needle is contaminated. This is, however, very rare. You may ensure that your phlebotomist takes out the needle in front of you from a sterile pack.
- Multiple pricks if the blood vessel is not easily found
- Excessive bleeding at the puncture site- Please inform your healthcare provider if you are taking any blood thinners or have any bleeding disorders.
- Light-headedness due to stress or heavy bleeding.
Minor pain and bruising that might occur will resolve on their own in a very short time.
Result
The result will provide the sodium levels in the blood, which are typically measured in millimoles per liter (mmol/L).
- Normal range: The result will indicate whether the person’s sodium levels fall within the normal range, which is generally between 135 and 145 mmol/L.
- Abnormal levels: If the person’s sodium levels are higher or lower than the normal range, the result will indicate this and may provide further information about the significance of the abnormal levels.
- Symptoms: If the person has been experiencing symptoms such as nausea, vomiting, headaches, or confusion, the result may provide information about whether these symptoms are related to their sodium levels.
- Medical conditions: The result may provide information about medical conditions that can affect sodium levels, such as kidney disease, heart failure, or liver disease.
| Sodium Level | Range | Units |
| Normal | 135 and 145 | millimoles per liter (mmol/L) |
| Abnormal | >135 or <145 | millimoles per liter (mmol/L) |
Limitations
- Certain medications, supplements, or medical conditions can interfere with sodium levels and lead to false readings. It’s important to inform your healthcare provider about any medications or medical conditions you have before the test.
- Normal sodium levels can vary depending on the laboratory and the method used to perform the test. Your healthcare provider will interpret your results based on the reference range provided by the laboratory.
- In some cases, a sodium test may not provide enough information to diagnose or monitor a condition. Additional tests or examinations may be necessary.
Conclusion
In conclusion, a sodium blood test is a commonly performed diagnostic test that measures the amount of sodium in the blood. It is a valuable tool for assessing fluid and electrolyte balance and can aid in the diagnosis and monitoring of various medical conditions.
While there are some limitations to the test, including false readings and inconclusive results, it remains an important tool in the management of certain medical conditions. As with any medical test, it’s important to discuss the risks, benefits, and limitations of a sodium test with your healthcare provider.
FAQs
The sodium test may be ordered to diagnose and monitor conditions that affect sodium levels in the body. Such conditions are dehydration, heart failure, kidney disease, or liver disease. It may also be ordered to monitor the effects of certain medications or treatments that affect sodium levels.
A healthcare provider will typically draw a small sample of blood from a vein in your arm using a needle and syringe. The sample is then sent to a laboratory for analysis.
No, fasting is not typically required for a sodium test. However, you may be asked to avoid eating or drinking anything for a few hours before the test.
The normal range for sodium levels in the blood is typically between 135 and 145 milliequivalents per liter (mEq/L).
Abnormal sodium levels can indicate a variety of conditions. Low sodium levels (hyponatremia) may indicate dehydration, heart failure, kidney disease, or liver disease. High sodium levels (hypernatremia) may indicate dehydration, diabetes insipidus, or certain medications or treatments.
Treatment for abnormal sodium levels depends on the underlying cause. For low sodium levels, treatment may involve fluid and electrolyte replacement. Where as, the high sodium levels may require fluid restriction or medication adjustments.
