What is the UFR Test?
The Urine Full Report (UFR), also known as a routine urine examination or urinalysis, is one of the most commonly ordered laboratory tests. It provides a comprehensive analysis of your urine by examining its physical appearance, chemical composition, and microscopic contents.
A UFR can reveal important clues about urinary tract infections, kidney disease, diabetes, liver problems, and many other conditions -- often before symptoms become obvious.
What Does the UFR Examine?
The test analyses your urine in three stages:
- Physical examination: Colour, clarity (turbid or clear), and odour
- Chemical examination (dipstick): pH, specific gravity, protein, glucose, blood, bilirubin, urobilinogen, nitrites, leukocyte esterase, and ketones
- Microscopic examination: White blood cells (pus cells), red blood cells, epithelial cells, casts, crystals, and bacteria
Why is This Test Done?
- To diagnose urinary tract infections (UTIs) -- one of the most common reasons
- To screen for kidney disease (protein or blood in urine)
- To monitor diabetes (glucose or ketones in urine)
- To investigate symptoms such as painful urination, frequent urination, blood-stained urine, or lower abdominal pain
- As part of routine health check-ups and pre-operative assessments
- To monitor treatment progress for kidney or urinary conditions
How to Collect a Clean Midstream Urine Sample
Step-by-Step Instructions
- Wash your hands thoroughly with soap and water.
- Clean the genital area with the provided wipe or clean water. For women: wipe from front to back. For men: retract the foreskin and clean the tip.
- Begin urinating into the toilet. Let the first portion of urine pass.
- Collect the midstream portion by holding the sterile container in the urine stream without touching the inside of the container.
- Finish urinating into the toilet (do not collect the last portion).
- Close the container tightly and label it with your name.
- Deliver the sample to the laboratory within 1 to 2 hours. Do not leave it in direct sunlight or heat.
Best time: An early morning (first void) sample is preferred as it is the most concentrated and gives the most accurate results.
Understanding Your Results
| Parameter | Normal Value | Abnormal Finding May Suggest |
|---|---|---|
| Colour | Pale yellow to amber | Red/brown (blood, haemoglobin), dark yellow (dehydration), cloudy (infection) |
| pH | 4.5 - 8.0 (usually ~6.0) | Alkaline pH: UTI with urea-splitting bacteria. Acidic pH: dehydration, diabetic ketoacidosis |
| Specific gravity | 1.005 - 1.030 | Low: overhydration, kidney disease. High: dehydration, diabetes |
| Protein | Nil or trace | Kidney disease, nephrotic syndrome, pre-eclampsia in pregnancy |
| Glucose | Nil | Diabetes mellitus (when blood sugar exceeds renal threshold) |
| Blood (RBC) | Nil or 0-2 per HPF | UTI, kidney stones, glomerulonephritis, bladder or kidney tumours |
| Pus cells (WBC) | 0-5 per HPF | Urinary tract infection, kidney infection (pyelonephritis) |
| Casts | Nil or occasional hyaline casts | RBC casts: glomerulonephritis. WBC casts: pyelonephritis. Granular casts: chronic kidney disease |
| Crystals | Few or nil | Calcium oxalate, uric acid, or triple phosphate crystals may indicate kidney stone risk |
| Bacteria | Nil | Urinary tract infection (needs confirmation with urine culture) |
| Nitrites | Negative | Positive suggests bacterial infection (certain Gram-negative bacteria) |
Common Findings and What They Mean
Urinary Tract Infection (UTI)
The most common abnormal finding. The UFR typically shows increased pus cells (>5 per HPF), bacteria present, and often positive nitrites. You may also notice cloudy, foul-smelling urine. If UTI is suspected, your doctor may order a urine culture to identify the exact bacteria and the right antibiotic.
Kidney Disease
Presence of protein (proteinuria), RBC casts, or granular casts may indicate kidney damage. Even small amounts of protein (microalbuminuria) can be an early warning sign, especially in diabetic patients.
Diabetes
Glucose in urine (glycosuria) usually appears when blood sugar exceeds approximately 180 mg/dL. Ketones in urine may indicate diabetic ketoacidosis, a serious complication requiring urgent medical attention.
UFR and the Sri Lankan Context
- UTIs are very common in Sri Lanka's hot and humid climate, especially among women. Dehydration from the heat increases the risk.
- Staying well hydrated is one of the simplest ways to prevent UTIs. Aim for at least 2 to 3 litres of water daily, more if you work outdoors or during hot weather.
- Do not delay urination -- holding urine for prolonged periods promotes bacterial growth in the bladder.
- Kidney disease is a growing concern. Annual UFR screening is recommended for anyone with diabetes, hypertension, or a family history of kidney disease.
What Should You Do Next?
- Normal UFR: No action needed. Maintain good hydration and hygiene.
- Suggestive of UTI: Your doctor may start antibiotics and order a urine culture for confirmation.
- Protein or blood detected: Further tests such as urine microalbumin, serum creatinine, or kidney ultrasound may be recommended.
- Glucose detected: A blood sugar test (FBS, PPBS, or HbA1c) should be done to evaluate for diabetes.
Important: A single abnormal UFR result does not necessarily mean you have a disease. Factors such as contamination during collection, recent exercise, menstruation, or certain foods can affect results. Always consult your doctor for proper interpretation.
