How it works

Kidney test

AED 200.00

The kidneys perform a number of important tasks in the body such as filtering the blood and producing urine. If they don’t work properly, it can lead to swelling, high blood pressure, fatigue and nausea. The causes of problems with the kidneys can be hereditary kidney diseases, diabetes, untreated urinary tract infection or high blood pressure.

What can Kidney test tell you

Measures important kidney markers.
Gives you insight into how your kidneys are doing.
Detects if you have a tendency towards impaired kidney function, which in its most serious form can be kidney failure.

What is tested in this package

What is Creatinine
The test measures the level of the substance creatinine in the blood and is a measure of how well the kidneys are working. Creatinine is a breakdown product of creatine phosphate found in muscle mass. Creatinine is normally excreted at an even rate via the kidneys, but if these do not function optimally, creatinine accumulates in the blood and the measured value rises.
What is Albumin
Albumin is formed in the liver and is the body’s most abundant protein. Albumin’s main task is to transport other proteins and substances in the bloodstream. Albumin is also important for the liquid to stay in the blood instead of ending up in the tissues and causing swelling, so-called oedema.
What is Calcium
Calcium is an element found in many different places in the body. 99% of all calcium is stored in our bones, but a small part is also found in the blood. The calcium concentration in the blood reflects to some extent the calcium metabolism in the body. Calcium is important for bones and teeth but also for muscle and nerve cells to function normally.
What is Potassium
Potassium is a mineral substance and one of the body’s salts or electrolytes. It is of great importance for the majority of different functions in the body, such as that the nervous system and muscle work work optimally. Along with other electrolytes such as sodium, potassium helps regulate the amount of fluid in the body and is part of the acid-base balance.
What is Sodium
Sodium is a mineral that is of great importance for the regulation of the body’s fluid and salt balance. It is also important for our cells to function normally. The sodium level in the body is meticulously regulated and this regulation takes place via several different organs, for example the brain, heart, kidneys and adrenal glands.
What is Cystatin C
Cystatin C is a protein that is formed in the body’s cells and is filtered and excreted via the kidneys. This means that it is also a good measure of kidney function. As cystatin C is not affected by the person’s muscle mass, gender or food intake (especially meat intake), it is a better marker for estimating kidney function than creatinine, especially in people with very high or low muscle mass. By analyzing cystatin C, you can also detect a mild impairment of kidney function earlier, long before the creatinine value starts to rise.
What is eGFR (cystatin C)
GFR, which stands for Glomerular Filtration Rate, is a measure of kidney function. The value shows the kidneys’ ability to filter the blood, and you then get an idea of ​​how well the kidneys’ ability to clean the blood from waste products works. eGFR (Cyst C) is an estimated value of kidney function calculated based on your value of cystatin C as well as your age and gender. The higher the cystatin C, the lower the eGFR and the worse the kidney function.
