What is the main test for kidney function?

Our test provides key information on kidney function. Our kidney test focuses on excretion and homeostasis, meaning the desired healthy steady state that is a good indicator of your health and wellness. The salts and minerals, known as electrolytes, help to regulate and control the balance of fluids in the body. Electrolytes ensure your system is functioning properly, help to regulate blood pressure, and contribute to correct muscle control and contraction.

What are the signs and symptoms of abnormal kidney function?

Are you concerned about the health of your kidney(s)? Our kidney function test can assess the health of your kidneys if you have any concerns or have experienced any of the symptoms below:

  • Irregular heartbeat
  • Fast heart rate
  • Fatigue
  • Lethargy
  • Convulsions or seizures
  • Nausea
  • Vomiting
  • Diarrhoea or constipation

What happens when I have taken my test?

After taking a blood sample in one of our clinics, we will send your sample to our fully accredited UK laboratory for analysis. We pride ourselves on our 1-day test turnaround time.

How can kidney function be tested?

Once the kidney function test is taken, we will review the following key elements in your body:

  • Sodium. Necessary for muscle and nerve function. Helps to control fluids in the body that impact blood pressure
  • Chloride. Essential for digestion. Helps to balance electrolytes, as well as acidity and alkalinity, which helps to maintain a healthy pH
  • Bicarbonate. Helps to maintain the acid/base balance that is essential to good health and works with the other electrolytes to maintain electrical neutrality at a cellular level
  • Urea. A waste product from your metabolism that is normally removed by your kidneys. Excess levels can indicate a problem with your kidney function
  • Creatinine. This is another breakdown product of muscle metabolism and an excellent indicator of kidney function and health

How will I receive my test results?

After just one working day of your sample's arrival at our accredited UK laboratory, your test results will be ready. Simply use your log-in details which will be sent to you after booking, to access your test results. Your test results will be located in your secure patient area. As soon as all your test results are available, one of our Patient Services team will contact you.

What happens if I have abnormal kidney function?

If your test reveals any abnormal levels of any of the key elements that are tested for, you should discuss your results with a doctor. You may be prescribed medication or be advised to take further tests to ensure the success of treatment. At Better2Know, we can arrange private consultations nationwide with our extensive network of skilled doctors.
