Kidney Function Test in Lagos

Chronic kidney disease is silent — most Lagos patients don't know their kidneys are failing until more than 60% of function is lost. A simple blood panel measures creatinine, eGFR, urea, and electrolytes to catch CKD years before symptoms appear.

Five Markers, Complete Kidney Picture

The KFT/U&E panel assesses filtration, waste removal, and electrolyte balance — the three core functions of healthy kidneys, all measured from a single blood draw.

🔍

Creatinine & eGFR

Creatinine is a muscle waste product filtered exclusively by the kidneys. Rising creatinine indicates falling filtration. eGFR (estimated glomerular filtration rate) converts creatinine to a percentage of normal kidney function — making it the standard metric for CKD staging across Lagos nephrologists.

  • eGFR ≥90: Normal (Stage 1)
  • eGFR 60–89: Mildly reduced (Stage 2)
  • eGFR 30–59: Moderate CKD (Stage 3)
  • eGFR <30: Severe / kidney failure

Urea & Electrolytes (U&E)

Urea (blood urea nitrogen) is a protein metabolism waste product cleared by the kidneys. Sodium, potassium, chloride, and bicarbonate (electrolytes) reflect fluid and acid-base balance — disturbances cause muscle cramps, irregular heartbeat, and confusion. Hyperkalaemia (high potassium) from CKD is a cardiac emergency.

  • Urea: 2.5–7.8 mmol/L normal
  • Sodium: 136–145 mmol/L
  • Potassium: 3.5–5.0 mmol/L
  • K+ >6.0 mmol/L: urgent cardiac risk
🦴

Uric Acid

Elevated uric acid (hyperuricaemia) causes gout — excruciatingly painful joint inflammation — and contributes to kidney stone formation. Uric acid rises when kidneys fail to excrete it efficiently. Lagos patients on high-purine diets (offal, sardines, alcohol) are particularly at risk.

  • Men: 208–428 µmol/L normal
  • Women: 155–357 µmol/L normal
  • >600 µmol/L: gout crystal formation risk
  • Gout common in Lagos adult males

Who Needs a Kidney Test in Lagos?

💉
Diabetes & hypertension (annual screening) Diabetic and hypertensive nephropathy are the leading causes of CKD in Lagos. Annual KFT is mandatory for all Lagos patients with either condition — these diseases are often managed together without kidney monitoring.
🦵
Oedema (leg swelling) or reduced urination Peripheral oedema and reduced urine output are classic signs of impaired kidney function. A KFT distinguishes kidney-origin oedema from cardiac or liver causes — common differential in Lagos emergency presentations.
💊
Regular NSAID or herbal supplement use NSAIDs (ibuprofen, diclofenac) and many Lagos herbal concoctions are nephrotoxic. Anyone taking these regularly should have annual kidney monitoring to detect early damage.
🦴
Gout or kidney stones Uric acid is measured in our KFT panel — essential for Lagos patients with known gout or those on allopurinol, where urate monitoring guides dose adjustment.
💊
Before nephrotoxic medications Aminoglycoside antibiotics, contrast dyes (for Lagos CT/MRI scans), and certain antiretrovirals require baseline renal function checking before administration.
CKD Staging by eGFR
eGFR ≥90 mL/min — Stage 1 Normal filtration. Annual monitoring if risk factors present.
eGFR 60–89 — Stage 2 Mildly reduced. Optimise blood pressure and glucose. 6-monthly monitoring.
eGFR 30–59 — Stage 3 (a/b) Moderate CKD. Nephrologist referral recommended. Quarterly monitoring.
eGFR <30 — Stage 4/5 Severe or kidney failure. Prepare for renal replacement therapy planning in Lagos.

Simple Steps for Accurate Results

1

Stay Well Hydrated

Drink adequate water the evening before and morning of your test. Dehydration transiently raises creatinine and urea, making kidneys appear worse than they are. Lagos patients arriving early in the morning should drink water en route — even if fasting for glucose tests added to the same panel.

2

Morning Sample Preferred

Morning sampling is preferred for creatinine — diurnal variation is minimal but consistency across monitoring visits matters. Avoid intense exercise for 24 hours beforehand: muscle breakdown from exercise transiently raises creatinine, which can be misinterpreted as kidney decline.

3

List All Medications

Bring a complete medication list — particularly NSAIDs (ibuprofen, diclofenac), ACE inhibitors (lisinopril, enalapril), diuretics, metformin, and antiretrovirals. All affect KFT interpretation. Do not stop medications without your Lagos doctor's guidance.

🔬
CKD-EPI eGFR calculation

We use the CKD-EPI 2021 equation (race-free, creatinine-based) for eGFR — the current international standard preferred by Nigerian nephrologists over older MDRD calculations.

📋
CKD staging on every report

Your report includes the eGFR-based CKD stage alongside raw values — making it immediately actionable for Lagos GPs and nephrologists without manual calculation.

📈
Longitudinal tracking for Lagos CKD patients

We retain records for monitoring patients — enabling eGFR trajectory analysis across quarterly visits, which is the most important predictor of dialysis need.
