Biomarkers

  1. Creatinine

    A waste product from normal muscle activity, removed from the blood by the kidneys. Raised creatinine is a reliable indicator that the kidneys are not filtering efficiently.

  2. Urea

    A waste product produced when the body breaks down protein, filtered out of the blood by the kidneys. Elevated urea can indicate reduced kidney function or dehydration.

  3. Uric Acid

    A byproduct of the breakdown of purines, found in certain foods and body tissues. High levels can lead to gout, a painful form of joint inflammation, and are also associated with kidney stones.

  4. Calcium

    Calcium is the most abundant mineral in the body, with the vast majority stored in the bones and teeth. In the blood, calcium plays a critical role in muscle contraction, nerve signalling, blood clotting, and hormone secretion. A calcium blood test measures the level of calcium circulating in the serum and is used to assess bone health, parathyroid function, and kidney health, as well as to investigate symptoms such as muscle cramps, fatigue, or bone pain.

  5. Albumin

    Normal Range: 3.5–5.5 g/dL
    Albumin is a protein produced by the liver that helps maintain fluid balance and transport various substances in the blood. Low albumin levels may indicate liver disease or conditions affecting protein production.

Monitor your kidney health and metabolic function with our comprehensive, private Kidney Function Blood Test Kit. Whether you want to assess renal filtration, manage conditions like high blood pressure or diabetes, or check for metabolic imbalances, testing your key kidney markers provides vital, clinical-grade insights into how your body is performing.

This test is specifically engineered for anyone monitoring chronic conditions, managing medications that impact renal health, or wanting to proactively check their overall kidney function. Routine testing offers a reliable baseline to measure changes, identify potential renal strain, and track trends over time.

Biomarkers/Parameters Tested & Reported

  • Creatinine: A waste product produced by muscle metabolism and cleared by the kidneys. Elevated levels in the blood may indicate reduced kidney function.

  • Urea: Measures nitrogen content derived from protein metabolism, helping evaluate the kidneys' ability to filter waste.

  • Uric Acid: A byproduct of purine metabolism regulated by the kidneys; high levels can contribute to conditions like gout.

  • Albumin: A vital blood protein that helps maintain fluid balance, serving as a key indicator of overall organ health.

  • Calcium: An essential mineral regulated by the kidneys, vital for bone health, nerve signaling, and cardiovascular function.

Who Should Take a Kidney Function Blood Test?

  • Individuals Monitoring Blood Pressure or Diabetes: Keep a close eye on markers commonly linked to secondary renal strain.

  • Proactive Health Tracking: Anyone looking to establish a baseline or monitor long-term metabolic and kidney performance.

  • Those on Medication: Individuals taking prescription drugs that require routine monitoring of kidney clearance.

How to Prepare & Take Your At-Home Kidney Test

  • Stay Well-Hydrated: Drink plenty of water before taking your test to encourage blood flow for an easy finger-prick sample.

  • Follow Any Fasting Guidance: Check if your specific protocol requires fasting to ensure accurate baseline readings for metabolic parameters.

Common Symptoms of Kidney & Metabolic Imbalances

While early-stage kidney issues often develop without noticeable symptoms, common signs of advanced strain include:

  • Changes in urination frequency or patterns

  • Fatigue, weakness, or unexplained brain fog

  • Swelling in the ankles, feet, or hands

  • High blood pressure or persistent fluid retention

Frequently Asked Questions

What is the difference between creatinine and urea?

Creatinine is a waste product specifically from muscle breakdown, while urea comes from protein metabolism. Both are filtered out by the kidneys and are measured together to give a clear picture of renal function.

How quickly will I receive my lab results?

Once your finger-prick sample reaches our accredited UK laboratory, your sample will be processed and reviewed by a doctor. Your confidential results will be uploaded to your secure digital dashboard within 1 to 3 working days.
