SODIUM & POTASSIUM (Na & K)

An electrolyte is a charged mineral that is important in the functioning of the human body. Sodium (Na) and potassium (K) are the two types of electrolytes and their functions are to regulate the movement of body fluids, conduction of nerve impulses, functioning of muscles, regulation of blood pressure and heart rate.

Electrolytes test (Na & K) is one of those blood tests which help in measuring the potassium and sodium levels existing in the body. The doctor may either recommend the test regularly or at any instance when he suspects any possible inequality in body fluid levels.

The process of Electrolytes testing is done by City Imaging and Clinical Labs using the latest laboratory techniques to guarantee the most reliable results and help the doctor identify the health condition of the patients as well as any imbalances in the electrolytes of the body. The price of the Electrolytes Test (Na & K) is usually from INR 250 to INR 700.

What Is an Electrolytes Test (Na & K)?

The Electrolytes Test (Na and K) indicates the presence of the two most important electrolytes in the blood, namely:

• Sodium (Na)
• Potassium (K)

Even though sodium and potassium are only needed in small amounts in the body, they play an essential role in a number of bodily functions. Sodium is mainly present in the fluid surrounding the cells, while potassium is mainly located inside the cells. The transmission of sodium and potassium across the cell membranes facilitates the production of the electrical signals necessary for the functioning of the nervous system and muscles.

Why are Sodium and Potassium important?

Sodium

This element is essential for normal functioning of nerves and muscles. The sodium level in blood is directly related to water content in the body. As a result, excessive intake of liquids, death of tissues, or various illnesses can make the levels of sodium abnormal.

Potassium

Potassium is very important for the contraction of muscles, the activity of nerves, and normal heartbeat. Dramatic changes in potassium levels can affect the functioning of the heart.

Kidneys remove unwanted potassium from the organism. Thus, abnormal potassium levels can be observed in case of impaired work of kidneys or to adverse effect of medicines on potassium balance.

When is the Electrolytes Test recommended?

A physician may suggest sodium and potassium testing for various factors. It can be part of standard blood tests or prescribed if the patient exhibits certain symptoms that may be the result of an electrolyte imbalance.

This test may be necessary for patients showing:

• Unusual weakness
• Muscle cramps
• Nausea
• Headache
• Drowsiness
• Excessive thirst
• Frequent urination
• Dizziness
• Irregular heartbeat
• Dehydration
• Persistent diarrhea

What does a Low Sodium Level mean?

Hyponatremia is a term used to refer to sodium levels falling below normal limits. It can happen when an individual has either too much water on board in contrast to sodium or an abnormally high loss of sodium.

Some possible causes are:

• Excessive sweating
• Prolonged vomiting
• Certain medications
• Kidney problems
• Liver disease
• Heart failure
• Hormonal disorders
• Excessive water intake in certain circumstances

What does a High Sodium Level mean?

Hypernatremia is a condition that signifies a sodium concentration that exceeds normal limits. Generally, hypernatremia, or any condition in which the level of sodium is high exists when there is not enough water in the body compared to sodium.

What does a Low Potassium Level mean?

A potassium level below the normal range is called hypokalemia.

Low potassium may occur because of:

• Vomiting
• Excessive sweating
• Certain diuretic medicines
• Poor nutritional intake
• Some hormonal conditions
• Certain kidney disorders

What does a High Potassium Level mean?

Hyperkalemia is a condition in which potassium levels are too high. It can cause kidney failure, which is responsible for potassium regulation in the bloodstream. High blood potassium levels may also result from specific drugs and diseases. Interestingly, sometimes the potassium reading can be falsely high due to damaged blood cells during blood collection or shortly after it happens. This condition is called hemolysis, and if the results do not match the reported clinical picture, the physician may recommend the repeat of the study.

Excess potassium may affect heart function and may be considered to have a potential health implication.

How is the Sodium and Potassium (Na & K) Test performed?

A small amount of blood needs to be collected for testing. Blood collection is made from the vein in the arm of the patient by a trained health professional.

Once the blood is collected, it will be placed in a tube, labelled correctly and sent for testing. Blood collection takes only a few minutes.

There may be a slight pain or stinging sensation as blood is collected, but these are usually mild symptoms.

What are the factors that can affect Electrolyte results?

The results of sodium and potassium measurements are affected by multiple factors, including the level of hydration, dietary intake, medicines used, kidney function, hormones' condition and fluid losses.

The method of blood collection and manipulation can affect the potassium level. For example, squeezing the arm to yield the blood or making collection difficult may lead to hemolysis and a falsely elevated potassium level.

Therefore, the results cannot always be interpreted on their own. The abnormal findings are compared with kidney tests, levels of glucose and blood pressure, urine tests and symptoms experienced by the patient.

Frequently Asked Questions (FAQ)

Is fasting required before taking the test?

Normally, fasting is not required before taking a sodium and potassium test, but a person may have to fast if other tests are also done at the same time.

What is the other name of Electrolyte Test?

It is also known as Sodium and Potassium (Na & K), Serum Electrolytes Test.

Are medicines able to alter sodium and potassium levels?

Yes, many medicines, including some diuretics and medicines that have an effect on the kidneys, alter the levels of electrolytes.

Is an abnormal electrolyte level always something serious?

Not always. The seriousness of an abnormality is determined by the extent of the abnormal deviation, the rate of change of the level, symptoms, and the causes of the condition.
