Kidney health

Urea

Urea is a waste product produced by the body when it breaks down proteins in the liver. Once the urea is made, it is transported to the kidneys, which filter it out of the blood and remove it from the body in the form of urine. Measuring the levels of urea in the blood can therefore reflect how well both the liver and the kidneys, are functioning. It is important to note that even if one kidney is severely damaged but the other is functioning perfectly, results may still return as normal.

Creatinine

Creatinine is a chemical waste molecule that is generated from normal muscle metabolism. Measurement of this is an indicator of the levels of other waste products in the body. Creatinine is also an accurate marker of kidney function, and may help in diagnosing kidney disease.

eGFR

The estimated glomerular filtration rate (eGFR) assesses how well the kidneys are working by estimating the amount of blood filtered through the kidneys. The glomeruli are tiny filters in the kidneys responsible for removing waste products. If these filters do not do their job properly, kidney function can be impaired. The eGFR calculation is an estimate of actual glomerular filtration rate, calculated using your age, gender, ethnicity, and serum creatinine levels.

Sodium

We do not report on sodium levels in fingerprick samples. This is because there is a small chance of a lower than expected result.Ê Sodium is both an electrolyte and a mineral. It helps to regulate the water and electrolyte balance of the body, and is therefore an important factor in blood pressure and pH. It also plays an important role in the function of nerves and muscles. Sodium levels in the blood are regulated by the kidneys.
