Kidney Function Test

Check Your Kidney Health with a Simple Blood Test

What Is a Kidney Function Test?

A Kidney Function Test assesses how well your kidneys are filtering waste, balancing fluids, and regulating key minerals in your body. It involves a blood test (for markers like creatinine and urea) and sometimes a urine test (for protein or abnormalities).

The kidneys play a vital role in your overall health—but kidney disease often develops silently, with few symptoms in the early stages. Routine testing helps detect problems early, before they progress.

At Regis Medical, we offer quick, accurate kidney testing with doctor consultation and follow-up recommendations.

What’s Included in a Kidney Function Test?

Blood Test Components:

  • Creatinine – Measures waste product filtered by the kidneys
  • Urea – Reflects nitrogen waste in the blood
  • eGFR (Estimated Glomerular Filtration Rate) – Indicates how well your kidneys are filtering
  • Electrolytes – Sodium, Potassium, Chloride, Bicarbonate (for fluid balance and nerve function)

Optional Add-ons:

  • Urine Test (Urinalysis) – Detects protein, blood, or other abnormalities
  • Microalbumin Test – Sensitive test for early kidney damage in diabetics
  • Calcium and Phosphate – Related to kidney-related bone health

Why Is Kidney Testing Important?

Chronic Kidney Disease (CKD) is common in Singapore, especially among adults with diabetes, hypertension, or high cholesterol. In early stages, kidney damage causes no symptoms—but once lost, kidney function cannot be fully restored.

You should consider testing if you:

  • Have diabetes or high blood pressure
  • Have a family history of kidney disease
  • Are over age 40 and have risk factors
  • Experience fatigue, leg swelling, or frequent urination
  • Are on medications that may affect kidneys (e.g. painkillers, antibiotics, supplements)
  • Have had abnormal urine tests or blood pressure readings

Symptoms That May Indicate Kidney Problems

  • Swelling in ankles, feet, or face
  • Fatigue or shortness of breath
  • Foamy or bloody urine
  • Frequent urination, especially at night
  • High blood pressure
  • Nausea, poor appetite
  • Difficulty concentrating or mental fog

Don’t wait for symptoms—early testing allows for earlier lifestyle or treatment interventions.
