RenalCheck Extended

RenalCheck Extended

This test offers a detailed evaluation of kidney function and electrolyte balance, helping to detect early signs of kidney stress, chronic kidney disease, or metabolic imbalances. It includes all markers in the basic screen such as Creatinine, Urea, and eGFR plus advanced biomarkers like Cystatin C and Uric Acid for a more comprehensive assessment of renal performance.

What Gets Assessed?

  • Basic Kidney Function Panel Includes:

    • Creatinine 
    • Estimated Glomerular Filtration Rate (eGFR) 
    • Calcium (Adjusted) 
    • Chloride 
    • Magnesium 
    • Phosphate 
    • Potassium 
    • Sodium 
    • Urea 

  • Advanced Kidney Health Panel Also Includes:

    • Cystatin C: a sensitive marker of kidney function, especially useful when creatinine-based eGFR may be inaccurate.
    • Uric Acid: elevated levels may indicate reduced kidney clearance, gout risk, or metabolic dysfunction.

Why RenalCheck Extended Matters?

Kidneys play a vital role in filtering waste, balancing electrolytes, and regulating blood pressure. Early-stage kidney dysfunction often goes unnoticed until it becomes severe. This extended panel offers a deeper insight beyond routine tests, helping to monitor kidney filtration efficiency, detect metabolic disturbances, and prevent long-term complications through timely intervention.

FAQs

Who should get the RenalCheck Extended?

It’s ideal for individuals with diabetes, hypertension, frequent urinary issues, a family history of kidney disease, or those taking medications that may impact kidney function.

What is the benefit of including Cystatin C and Uric Acid?

Cystatin C offers a more accurate estimate of kidney function, especially in older adults or those with muscle loss. Uric acid levels can indicate gout risk and metabolic load, offering broader insight into renal health.

Do I need to fast before this test?

Fasting is not strictly required, but may be recommended depending on your doctor’s advice or if additional panels are ordered alongside.

Can this test detect early kidney disease?

Yes. The combination of standard and advanced biomarkers makes it suitable for identifying even mild or early-stage kidney dysfunction.

How is the test performed?

A venous blood sample is taken at one of our UK-wide phlebotomy clinics. Results are typically available within 48–72 hours.
