Kidney disease has no symptoms until 60–70% of kidney function is lost. Diabetes and hypertension — both epidemic in Lagos — are the leading causes of chronic kidney disease. A kidney function test at Mascot Healthcare, Akoka identifies early damage before it becomes irreversible.
These are the symptoms and situations that indicate this test is the right next step.
Annual kidney function testing is mandatory for all patients with diabetes or hypertension — both cause progressive kidney damage.
Annual kidney screeningOne-sided or bilateral flank pain — especially with urinary symptoms — may indicate kidney infection, stones, or obstruction.
KFT + abdominal scanRegular ibuprofen, diclofenac, and other NSAIDs damage the kidneys when used chronically — KFT monitors for drug-induced nephropathy.
Drug toxicity monitoringBilateral leg oedema without heart failure may indicate nephrotic syndrome — the kidneys leaking protein, causing fluid retention.
KFT + urine proteinRecurrent upper urinary tract infections can cause progressive kidney scarring (reflux nephropathy). KFT assesses cumulative damage.
KFT + kidney scanLate-stage chronic kidney disease causes uraemia — accumulation of waste products causing profound fatigue, nausea, and reduced urination.
Urgent KFTUnderstanding what each component of the test measures helps you understand your results.
Waste product from muscle metabolism — filtered entirely by the kidneys. Elevated creatinine indicates reduced filtration capacity.
Calculated from creatinine, age, and sex — the most clinically useful measure of kidney function. eGFR <60 mL/min/1.73m² for >3 months = chronic kidney disease.
Another waste product filtered by kidneys. High urea + high creatinine = kidney failure; high urea alone may indicate dehydration or high protein diet.
Elevated in gout and kidney disease — uric acid crystals deposit in joints (gout) and kidney collecting system (uric acid stones).
| eGFR (mL/min/1.73m²) | CKD Stage | Meaning |
|---|---|---|
| ≥90 | Stage 1 (with kidney damage) | Normal or high — monitor if kidney damage present |
| 60–89 | Stage 2 | Mildly reduced — monitor annually if risk factors |
| 30–59 | Stage 3 | Moderately reduced — nephrology referral |
| 15–29 | Stage 4 | Severely reduced — prepare for renal replacement |
| <15 | Stage 5 | Kidney failure — dialysis or transplant |
A 4–6 hour fast improves accuracy. Avoid high-protein meals the day before as these temporarily raise creatinine.
Drink water normally — dehydration elevates creatinine independently of kidney disease.
