Who should take the test?

Your kidneys are a vital part of your health. They remove wastes from the body, clean your bodily fluids. Every minute, about one liter enters the kidneys and is cleaned there, before flowing back into the body. Your Kidney Test results reflect how well your kidneys are working. Abnormal kidney function can cause accumulation of waste products in the body, which can lead to fatigue, headaches, nausea, and more.

With our Kidney Test your kidney status will be determined based on the following markers:

  • Blood urea nitrogen (BUN)
  • Creatinine (CREAT)
How does it work?

Once your order has been processed, you will be sent a blood sample collection kit. You collect your sample from the comfort of your own home and send it back to us. We analyze your sample and send your results via secure email with a password protected PDF file.

Test measures
For the Kidney Test we analyze:
  • Blood urea nitrogen (BUN)
  • Creatinine (CREAT)
Blood urea nitrogen (BUN)

Blood urea nitrogen (BUN) is a waste product formed during the process in which our bodies break down proteins. It travels into the kidneys and healthy kidneys then filter the urea through urine. Increased BUN levels may indicate that the kidneys are unable to effectively remove urea. As such, measuring the BUN level helps to evaluate the kidney function.

Creatinine (CREAT)

Creatinine (CREAT) is another waste product. It is formed by the breakdown of creatine, a key molecule in muscular metabolism. Healthy kidneys are removing creatinine and expel it in urine. A kidney or urinary tract disorder reduces the excretion of creatinine and thus raises the creatinine levels. Therefore, creatinine levels are a good indicator to evaluate kidney function.

Symptoms the Kidney Test is suitable for:
  • Fatigue
  • Lack of concentration
  • Insomnia
  • Swelling around the eyes, face, wrists, abdomen, or ankles
  • Decrease or discoloration of urine
  • Mid-back pain
  • Nausea / vomiting
  • Loss of appetite

Any Questions?

Here are some of the most frequently asked questions regarding this test. Your question is missing? Please contact us at:

Why is it important to monitor kidney function?

Monitoring kidney function is crucial because the kidneys play a vital role in filtering waste products from the blood and maintaining overall bodily health. Any impairment in kidney function can lead to the accumulation of toxins in the body, causing various health issues.

I am not getting enough blood from my finger, what can I do?

Prepare the blood draw well: Hold your hand a little longer under warm water and circle your arm to stimulate blood circulation. Prick the finger on the side, not directly on top of the fingertip. The middle or ring finger of the non-dominant hand is usually best. When piercing, place your finger on a firm surface to avoid unconscious pulling back. A light squeeze and massage towards the fingertip helps stimulate blood flow. Alternatively, blood can be taken from the earlobe or from the vein (at the doctor's).

What are the symptoms of kidney dysfunction?

Symptoms of kidney dysfunction include: Fatigue, lack of concentration, insomnia, swelling around the eyes, face, wrists, abdomen, or ankles, decrease or discoloration of urine mid-back pain, high blood pressure, nausea / vomiting and loss of appetite.

What can affect the kidney function?

Things that can affect kidney function are: A bacterial infection, reduced blood flow to the kidneys due to dehydration/ congestive heart failure/ diabetes, kidney stones or a high protein diet.

I am pregnant and my BUN levels are increased.

During pregnancy, BUN levels usually fluctuate, so increased levels during pregnancy are not a cause for concern. Creatinine blood levels on the other hand are generally slightly lower during pregnancy, which is also no cause for concern.
