I booked this test after persistent muscle cramps and fatigue. The home collection was smooth and the nurse was very professional. My GP used the results to quickly adjust my hydration and supplements.

Frequently Asked Questions

What markers are tested in the Kidney Function Test?

This panel measures:

  • Creatinine
  • Urea
  • eGFR (Estimated Glomerular Filtration Rate)
  • Sodium
  • Potassium
  • Chloride
  • Bicarbonate

These results together assess kidney filtration, hydration, and electrolyte balance.

Why is eGFR important?

eGFR estimates how well your kidneys are filtering waste from your blood. A lower eGFR may indicate reduced kidney function or early kidney disease.

Who should consider this Kidney Function Test?

This test is particularly useful for:

  • People with high blood pressure or diabetes
  • Those on long-term medications
  • Athletes or people training intensely
  • Anyone with a history of kidney stones or infections
  • Individuals with swelling, fatigue, or abnormal urine output

Can dehydration affect my kidney test results?

Yes. Dehydration can raise:

  • Creatinine
  • Urea
  • Electrolyte levels

It’s important to drink normal amounts of water before your test (unless fasting is required for another test).

What does high creatinine usually mean?

High creatinine may be linked to:

  • Reduced kidney filtration
  • Dehydration
  • Muscle breakdown
  • Certain medications

Your GP will interpret the result based on your age, muscle mass, and overall health.

What happens if potassium is too high or too low?

Abnormal potassium can affect:

  • Heart rhythm
  • Muscle function
  • Nerve signals

Significant abnormalities require urgent medical review.

Is this test suitable for older adults?

Yes. Kidney function naturally changes with age, making this test very important for people over 50.
