Why Choose This Kidney Function Test?
This test measures three key markers commonly used to assess kidney filtration function and overall kidney health. By evaluating creatinine, estimated glomerular filtration rate (eGFR) and urea together, the panel provides a practical overview of how effectively the kidneys are filtering waste products from the blood.
Unlike traditional clinic-based testing, this service includes professional home blood collection by a qualified healthcare professional. Your sample is collected at a time and location convenient for you and transported for laboratory analysis.
Samples are analysed by a UKAS-accredited laboratory operating to ISO 15189 standards, ensuring high-quality testing and reliable results. Results are securely delivered online, typically within 1–3 working days following analysis.

Biomarkers included – Kidney Function Test
- Creatinine: Kidney Function — Creatinine is a waste product formed in muscles from the normal breakdown of creatine. It is released into the bloodstream and filtered by the kidneys, then excreted in urine. Because creatinine levels are influenced by how efficiently the kidneys filter blood, it is commonly used to assess kidney function. Elevated creatinine may indicate reduced kidney filtration or kidney disease, while low lev
- Urea: Kidney Function — Urea is a waste product formed in the liver through the breakdown of proteins. After formation, it is transported to the kidneys and eventually excreted in the urine. Measuring urea levels in the blood, often called blood urea nitrogen (BUN), is a common test used to evaluate kidney function. Elevated blood urea levels can indicate impaired kidney function or other issues affecting waste processin
- Estimated GFR: Kidney Function — Estimated Glomerular Filtration Rate (eGFR) is a calculated measure used to assess how well the kidneys are filtering waste products from the blood. It is a critical indicator of overall kidney function and is used to detect, stage, and monitor chronic kidney disease.
Frequently asked questions – Kidney Function Test
Can this test help if I have changes in urination or fluid balance?
Yes. Kidney Function Test includes creatinine, estimated GFR and urea, which can provide useful context around kidney filtration, waste product clearance and fluid related changes.
What does estimated GFR show?
Estimated GFR gives an indication of how well the kidneys are filtering blood. It is calculated using creatinine and provides broader kidney function context.
Can I reschedule my appointment?
Yes, appointments can be rearranged. Please provide sufficient notice before your scheduled appointment.
What happens if my sample cannot be analysed?
If a sample is unsuitable for analysis, our customer support team will contact you with information about the next steps.
