Urine Test Results Explained
What your urinalysis results mean in plain English
A urine test (urinalysis) is one of the oldest and most informative medical tests available — providing clues about kidney disease, urinary tract infections, diabetes, liver disease, and more. In Nigerian health facilities, a basic urine dipstick test costs very little and gives immediate results. More detailed urine microscopy and culture helps identify infections. Despite its value, urine test results are often given to patients without explanation. This guide decodes every parameter of your urinalysis result.
Signs and Symptoms
✓ Urinalysis ordered for: UTI symptoms (burning urination, frequency), kidney disease screening, diabetes monitoring, pregnancy (ANC), pre-operative assessment, fever investigation, blood or protein in urine
✓ Early morning urine (mid-stream) is most concentrated — best for dipstick and culture
✓ Clean-catch technique: clean genital area, pass first stream of urine away, collect middle of stream in container
When to Seek Help
Blood in urine (haematuria) visible to naked eyePainless haematuria in adults > 40 = bladder cancer until proved otherwise. Always investigate — don't assume it's a UTI
Protein 3+ or 4+ on dipstickSignificant proteinuria — may indicate nephrotic syndrome, diabetic nephropathy, or glomerulonephritis. Quantify with ACR and check kidney function
Nitrites + leucocytes + symptomsLikely UTI — start antibiotics after sending urine for culture
Glucose in urine in a non-diabeticBlood glucose should be checked — this may be the first sign of undiagnosed diabetes
Ketones 3+ in a diabeticSuggests diabetic ketoacidosis (DKA) — especially with high blood sugar and vomiting. Medical emergency
Tests & Diagnosis
🧪 Colour
Normal: pale to amber yellow. Cloudy = infection or crystals. Dark orange/brown = bilirubin (liver disease, bile duct obstruction). Red/pink = blood (haematuria). Black = severe haemolysis, melanoma, alkaptonuria. Green = Pseudomonas infection, amitriptyline
🧪 Specific gravity (SG)
Normal 1.001–1.035. High SG (concentrated urine, > 1.020) = dehydration, ADH secretion. Low SG (dilute, < 1.005) = diabetes insipidus, excessive fluid intake, CKD with impaired concentration
🧪 Protein
Normal: trace or negative. 1+ may be postural (standing). 2–4+ = significant proteinuria. Causes: UTI, kidney disease (diabetic nephropathy, glomerulonephritis, nephrotic syndrome). Quantify with 24-hour protein or ACR
🧪 Glucose
Normal: negative (blood glucose must exceed ~10 mmol/L to spill into urine). Positive = diabetes (blood glucose > renal threshold), pregnancy (lower threshold), renal glycosuria (benign — low renal threshold)
🧪 Leucocytes (white blood cells)
Positive = pyuria — white cells in urine from infection or inflammation. Combine with nitrites for UTI prediction
🧪 Nitrites
Produced when Gram-negative bacteria (E. coli, Klebsiella) metabolise urinary nitrates. Positive nitrites + leucocytes + symptoms = UTI. False negative if Gram-positive bacteria (Staphylococcus, Enterococcus)
🧪 Ketones
Produced when fat is metabolised instead of glucose. Positive in: starvation, prolonged vomiting, diabetic ketoacidosis (DKA), very-low-carb diet (ketogenic diet)
🧪 Blood/Haemoglobin
Positive dipstick detects free haemoglobin and intact red cells. False positive with myoglobin (muscle breakdown), contamination with menstrual blood. Must confirm with microscopy — true haematuria requires investigation
Frequently Asked Questions
My urine dipstick showed 1+ protein — do I have kidney disease?
Not necessarily. Trace-1+ protein on a single dipstick can occur with dehydration, standing, fever, exercise, or UTI — these are not kidney disease. Significant proteinuria requires repeat testing (at least two positive results on early morning urine), ideally quantified with an albumin:creatinine ratio (ACR). Context matters enormously.
What is a clean catch urine sample and why does it matter?
Contamination of urine with skin bacteria is extremely common, especially in women — it leads to false positive UTI diagnoses and unnecessary antibiotic prescribing. A clean catch (clean the genitals first, discard the first stream, collect the middle) dramatically reduces contamination. Catheter specimens are gold standard for accuracy when contamination is suspected.
Can eating certain foods affect urine test results?
Yes. Beetroot causes red-pink urine (can mimic haematuria). High vitamin C intake causes false-negative glucose and blood on dipstick. Asparagus causes a distinctive smell. B vitamins cause bright yellow urine. Eating red meat before a dipstick can cause false-positive blood. Fast for 8 hours and avoid these foods before a urine test if possible.
What does 'pus cells 50/hpf' mean on microscopy?
Pus cells are white blood cells seen under the microscope — per high-power field (hpf). Normal < 5/hpf in women, < 2/hpf in men. 50/hpf is significantly elevated (severe pyuria), strongly suggesting UTI or kidney inflammation. Combined with a positive culture, this confirms infection and guides antibiotic choice.
