Using a Gentle Fingerprick Blood Sample, This Kidney Function Test Measures:

Bicarbonate (Bicarb) is both excreted and reabsorbed by your kidneys.

It serves to help maintain the acidity of your blood and tissues and interacts with other electrolytes (e.g. sodium, potassium, and chloride) to maintain optimum cellular chemistry.

The measurement of bicarbonate allows the estimation of your blood's acid-base balance and is an indicator of kidney performance.

Chloride (Cl) is an electrolyte which helps maintain the normal acid-alkali (pH) balance and levels of water in the body.

Chloride is eaten in the form of sodium chloride - salt - so it normally increases or decreases in direct relationship to sodium.

It is tested to assess if the body’s pH balance is correct.

Creatinine is a natural waste product formed in your muscles. It results from the breakdown of creatine during energy release - i.e. movement and exercise.

Nearly all creatinine is excreted by your kidneys, so measuring the level remaining in the blood can determine if your kidneys work normally.

Learn More

Your glomerular filtration rate (GFR) is a calculation made using your creatinine test levels, age and gender. It estimates how much blood passes through the microscopic filters - glomeruli - in the kidneys that are responsible for filtering waste products from your bloodstream. 

As such GFR is the best way to assess your overall level of kidney function.

A potassium test accurately measures the level of potassium in your blood. Although potassium is present in all bodily fluids, the majority is contained within the cells of your body. The amount released into the serum portion of your blood is usually closely controlled, mainly by the aldosterone hormone. However, many conditions can lead to serum concentration being too low or too high.

Potassium plays an important role in nerve signalling and muscle communication.  It also assists in the transfer of nutrients into cells and the removal of waste products in the kidneys.

Learn More

Sodium is essential to normal bodily function, playing a critical role in the maintenance of normal blood pressure. Sodium also helps regulate your body's fluid balance and aids in nerve and muscle communication.

Sodium levels in the blood, as well as all body water, are regulated by the kidneys ideally within a very narrow concentration range.

Abnormal blood sodium is usually due to an issue with hormone production or thirst and results in too little (dehydration) or too much (edema) body water content.

Learn More

Blood Urea Nitrogen (BUN) is a waste product naturally produced in your body.

Proteins eaten in your diet are processed by the liver and during this process blood urea nitrogen is released into the blood.

The BUN is passed to your kidneys and then healthy kidneys flush it from the body in urine.

As such, abnormal levels may indicate an issue with your kidney function.
