What is the purpose of this test?

The LetsGetChecked - Kidney Blood Spot Test Kit is a comprehensive and reliable tool designed to measure the levels of creatinine and eGFR in the blood, which are two essential indicators of kidney function. The test kit comes with easy-to-follow instructions and includes all the necessary materials for individuals to collect a small sample of blood in the comfort of their own homes. Once the blood sample is collected, it is sent back to the certified laboratory for analysis, and the results will be available online in just a few days. 


The results will provide detailed information about the kidney function and include an interpretation of the creatinine and eGFR levels. This interpretation will give individuals a clear understanding of their results and what they mean for their health. The test's results will also come with guidance on what an individual can do next, depending on their results. For example, if their results show that their kidney function is healthy, they may receive advice on how to maintain their kidney health. However, if their results show that their kidney function is impaired, they will receive guidance on how to manage their condition and advice on the next steps to take, including consulting a healthcare professional.


This test is particularly useful for people who have a family history of kidney problems or who are at risk for kidney disease due to other health conditions like diabetes or high blood pressure. It is also an excellent option for those who want to monitor their kidney function regularly, especially if they have a history of kidney disease or have undergone a kidney transplant. 


Overall, the LetsGetChecked - Kidney Blood Spot Test Kit is a reliable, accurate, and convenient way for individuals to monitor their kidney function and take control of their health.


The LetsGetChecked - Kidney Blood Spot Test Kit measures the following:

Urea - Urea is a waste product formed from the breakdown of proteins and is passed out in your urine. A high level of urea ('uremia') indicates that the kidneys may not function optimally or that you are dehydrated.


Creatinine - Creatinine is a waste product made by your muscles and dietary protein. Creatinine passes into the bloodstream and is usually passed out in urine. A high blood level of creatinine indicates that the kidneys may not be working properly.


eGFR (Estimated Glomerular Filtration Rate) - eGFR (estimated glomerular filtration rate) is a calculation that determines how well your kidneys are filtering blood.
