You hand over a small plastic container at the pathology lab, and a few hours later you receive a report filled with terms like "pus cells," "epithelial cells," "casts," and "trace protein." Your doctor glances at it for five seconds and says "UTI hai, antibiotics lo." But what do those numbers actually mean? And what if the report is hinting at something beyond a simple infection — early kidney damage, uncontrolled diabetes, or liver problems?
The urine routine and microscopy test is one of the most commonly ordered — yet least understood — tests in India. It costs as little as ₹100-300, requires no fasting, and can reveal a surprising amount about your urinary tract, kidneys, liver, and metabolic health. With urinary tract infections affecting over 50% of Indian women at some point in their lives, and India being home to over 10 crore diabetics at risk of kidney damage, learning to read your urine report is a skill every Indian should have.
What Is a Urine Routine and Microscopy Test?
A urine routine and microscopy test (also called Complete Urine Examination or CUE) is a three-part analysis of your urine:
Part 1: Physical Examination
Your lab technician first evaluates the urine's appearance:
| Parameter | Normal | What Abnormal Means |
|---|---|---|
| Colour | Pale yellow to amber | Red/brown = blood or haemoglobin; dark yellow = dehydration; orange = bilirubin or certain medications |
| Clarity | Clear | Turbid/cloudy = infection, crystals, or mucus |
| Volume | 800 – 2,000 mL/day | Low = dehydration, kidney disease; High = diabetes, excessive water intake |
Part 2: Chemical Examination (Dipstick)
A chemically coated strip is dipped into the urine sample, changing colour to detect various substances:
| Parameter | Normal Value | What Abnormal Suggests |
|---|---|---|
| pH | 4.5 – 8.0 (typically 5.5 – 6.5) | Low (<5.0) = acidic, may promote uric acid stones; High (>7.5) = UTI with urease-producing bacteria, may promote struvite stones |
| Specific Gravity | 1.005 – 1.030 | Low = dilute urine, excessive water; High = dehydration, diabetes |
| Protein | Nil or Trace | Positive = kidney damage (proteinuria), hypertension, diabetes |
| Glucose | Nil | Positive = uncontrolled diabetes (blood sugar typically >180 mg/dL), renal glycosuria |
| Blood | Nil | Positive = infection, stones, glomerular disease, menstrual contamination |
| Bilirubin | Nil | Positive = liver disease, bile duct obstruction |
| Urobilinogen | 0.2 – 1.0 mg/dL | Elevated = haemolytic anaemia, liver disease; Absent = bile duct obstruction |
| Ketones | Nil | Positive = diabetic ketoacidosis, prolonged fasting, low-carb diets |
| Nitrites | Negative | Positive = bacterial infection (especially E. coli) |
| Leukocyte Esterase | Negative | Positive = white blood cells present, suggesting infection or inflammation |
Part 3: Microscopic Examination
This is where the lab centrifuges your urine and examines the sediment under a microscope. Findings are reported per HPF (High Power Field):
| Finding | Normal Range | What Abnormal Means |
|---|---|---|
| Pus cells (WBCs) | 0 – 5/HPF | >5 = pyuria (infection or inflammation); >10 = likely UTI |
| Red blood cells (RBCs) | 0 – 2/HPF | >2 = haematuria (stones, infection, glomerular disease, tumour) |
| Epithelial cells | Few | Many squamous = contamination; renal tubular cells = kidney damage |
| Bacteria | Nil or Few | Many = UTI; confirm with urine culture |
| Casts | Occasional hyaline | RBC casts = glomerulonephritis; WBC casts = pyelonephritis; Granular casts = kidney disease |
| Crystals | Few or Nil | Calcium oxalate = stone risk; Uric acid = gout/acidic urine; Triple phosphate = infection |
| Mucus threads | Few | Many = irritation or inflammation of urinary tract |
When you upload your urine report to MedicalVault, the app extracts these values and lets you track changes over time — particularly useful if you are monitoring a recurring UTI or managing diabetes-related kidney markers.
Detecting UTIs: What Your Urine Report Reveals
Urinary tract infections (UTIs) are among the most common reasons an Indian doctor orders a urine test. Studies estimate that over 50% of Indian women will experience at least one UTI in their lifetime, with recurrence rates of 25-30%. In Indian men, UTIs are less common but increase significantly after age 50 due to prostate enlargement.
The UTI Pattern on Your Report
When you have a UTI, your urine report typically shows a characteristic combination:
- Pus cells (WBCs): Elevated, often >10/HPF and sometimes too numerous to count (TNTC)
- Nitrites: Positive (especially with E. coli, which causes 70-80% of community-acquired UTIs in India)
- Leukocyte esterase: Positive
- Bacteria: Present on microscopy
- RBCs: May be mildly elevated (haemorrhagic cystitis)
- pH: May be elevated (>7.5) if caused by urease-producing organisms like Proteus
Important: If nitrites are negative but pus cells are high, it does not rule out a UTI. Some bacteria (Enterococcus, Staphylococcus) do not convert nitrates to nitrites. Your doctor may still diagnose a UTI based on symptoms and pus cell count.
When to Get a Urine Culture
A simple urine routine test identifies that infection is likely present, but a urine culture and sensitivity (C&S) test identifies the exact bacterium and which antibiotics will work. Your doctor should order a culture when:
- First UTI with unusual features or in men (all male UTIs warrant a culture)
- Recurrent UTIs (two or more in six months)
- Treatment failure — symptoms persist after completing antibiotics
- Pregnancy — all pregnant women should be screened for asymptomatic bacteriuria
- Hospital-acquired infections — higher likelihood of resistant organisms
This is especially important in India where antibiotic resistance is a major concern. Studies show that E. coli resistance to commonly prescribed fluoroquinolones (Norflox/Ciplox) exceeds 50-70% in many Indian centres. Your doctor may prescribe based on culture sensitivity rather than empirically to ensure the right antibiotic is chosen.
Common antibiotics prescribed for UTI in India include:
- Nitrofurantoin (Furadantin, Urimax) — first-line for uncomplicated UTI; lower resistance rates
- Fosfomycin (Monurol, Fosfocin) — single-dose treatment; increasingly preferred
- Norfloxacin (Norflox) — widely used but growing resistance
- Ciprofloxacin (Ciplox, Ciprobid) — reserved for complicated UTIs due to resistance concerns
Never self-medicate with antibiotics for a UTI. Incomplete courses and inappropriate antibiotics drive resistance, making future infections harder to treat. Always consult your doctor and complete the full prescribed course.
Kidney Markers in Your Urine Report
Your urine report contains valuable early warning signs for kidney damage — often detectable years before your KFT (Kidney Function Test) shows abnormalities.
Protein in Urine (Proteinuria)
Healthy kidneys filter waste while retaining protein. When kidney filters (glomeruli) are damaged, protein leaks into the urine. On a routine dipstick:
| Dipstick Result | Approximate Protein | Significance |
|---|---|---|
| Negative | < 10 mg/dL | Normal |
| Trace | 10 – 20 mg/dL | May be normal; recheck if persistent |
| 1+ | 30 mg/dL | Mild proteinuria; investigate |
| 2+ | 100 mg/dL | Moderate; likely kidney involvement |
| 3+ | 300 mg/dL | Significant; needs urgent evaluation |
| 4+ | > 1,000 mg/dL | Severe; nephrotic range |
For diabetics: If your dipstick shows "negative" for protein, you are not out of the woods. Early diabetic kidney damage causes microalbuminuria — tiny amounts of albumin that the dipstick cannot detect. Studies show that 27-37% of Indian type 2 diabetics have microalbuminuria. Your doctor should order a urine albumin-creatinine ratio (UACR) test annually if you have diabetes or hypertension:
| UACR (mg/g) | Category | Action |
|---|---|---|
| < 30 | Normal | Continue annual screening |
| 30 – 300 | Moderately increased (microalbuminuria) | Start or intensify treatment; recheck in 3 months |
| > 300 | Severely increased (macroalbuminuria) | Urgent nephrology referral |
Track your UACR alongside your HbA1c and creatinine/eGFR on MedicalVault's trend analysis to monitor kidney health comprehensively.
Glucose in Urine (Glycosuria)
Glucose appears in urine when blood sugar exceeds the kidney's reabsorption threshold — typically around 180 mg/dL. If your urine test shows glucose, it usually means your diabetes is not well controlled. However, some people have a low renal threshold and spill glucose at lower blood sugar levels (renal glycosuria), which is benign. Your doctor will interpret this alongside your fasting blood sugar and HbA1c.
Note for SGLT2 inhibitor users: If you are on medications like Dapagliflozin (Forxiga, Oxra) or Empagliflozin (Jardiance), these drugs deliberately increase urinary glucose excretion to lower blood sugar. Positive urine glucose in this case is expected and not a cause for alarm — but it does increase UTI risk, which is why your doctor may monitor urine more frequently.
Casts: Tiny Cylinders That Tell a Story
Casts are cylindrical structures formed in the kidney tubules and flushed into the urine. They are like moulds of the tubules and indicate where in the kidney the problem lies:
- Hyaline casts: Occasional presence is normal, especially after exercise or dehydration
- Granular casts: Indicate chronic kidney disease or acute tubular injury
- RBC casts: Virtually diagnostic of glomerulonephritis — inflammation of the kidney's filtering units. This is a red flag requiring urgent evaluation
- WBC casts: Point to pyelonephritis (kidney infection) or interstitial nephritis
- Waxy casts: Suggest chronic, advanced kidney disease
- Epithelial cell casts: Indicate acute tubular necrosis
If your microscopy report mentions any casts beyond occasional hyaline, discuss it with your doctor promptly.
Crystals and the Kidney Stone Connection
India lies in the global "kidney stone belt" — a geographic zone where stone disease is highly prevalent due to climate, diet, and dehydration. Crystals in your urine report can be an early warning:
Common Crystals in Indian Patients
- Calcium oxalate (envelope-shaped): The most common crystal, seen in acidic urine (pH <6.5). High intake of oxalate-rich Indian foods — palak (spinach), chiku (sapota), tomatoes, peanuts, chocolate, and chai — can increase these crystals. Does not always mean stones, but recurrent high counts warrant investigation
- Uric acid (diamond or rhomboid-shaped): Found in very acidic urine (pH <5.5). Associated with high uric acid levels and gout. Common in people eating rich, protein-heavy diets
- Triple phosphate/struvite (coffin-lid shaped): Found in alkaline urine (pH >7.0). Almost always associated with UTI caused by urease-producing bacteria like Proteus. Can form large "staghorn" stones
- Calcium phosphate: Found in alkaline urine; often mixed with calcium oxalate stones
Practical Tips to Reduce Crystal Formation
- Drink at least 2.5-3 litres of water daily — critical in India's hot climate. Your urine should be pale yellow
- Reduce oxalate-rich foods if calcium oxalate crystals are recurrent — moderate your palak, chiku, and peanut intake
- Add nimbu (lemon juice) to water — citrate inhibits calcium stone formation
- Do not skip meals — irregular eating patterns concentrate urine
- Reduce excessive salt — high sodium increases calcium excretion in urine
How to Collect Your Urine Sample Correctly
A poorly collected sample can give misleading results — false positive bacteria, excess epithelial cells, and contaminated microscopy. Follow these steps for an accurate result:
Mid-Stream Clean-Catch Method
- Wash your hands thoroughly with soap
- Clean the genital area — women should wipe front to back with the provided antiseptic wipe; men should retract the foreskin and clean the tip
- Begin urinating into the toilet
- After a few seconds, hold the sterile container in the urine stream and collect the mid-stream portion
- Finish urinating into the toilet
- Cap the container immediately and hand it to the lab within 1 hour, or refrigerate if there will be a delay
Best Practices
- First morning sample is ideal — it is the most concentrated and gives the most accurate results for protein, glucose, and microscopy
- No fasting required — unlike blood tests, you can eat and drink normally
- Inform the lab if you are menstruating (women), on antibiotics, or taking any supplements that colour your urine (B-complex turns urine bright yellow)
- For children, the lab may provide a paediatric urine bag
Test Costs in India
The urine routine and microscopy test is one of the most affordable lab tests available:
| Test | Approximate Cost (₹) |

Prices vary by city and lab chain. Dr. Lal PathLabs, Thyrocare, SRL, and Metropolis often offer discounts when booking online or as part of health check-up packages.
Your preventive health check-up guide explains when to include urine tests as part of your annual screening.
When Should You Get a Urine Test?
Unlike a CBC or lipid profile, a urine routine test is not always part of routine check-ups. Your doctor will order one when:
- UTI symptoms — burning urination (dysuria), frequent urge to urinate, lower abdominal pain, cloudy or foul-smelling urine
- Kidney concerns — swelling in feet/face, foamy urine, blood in urine, family history of kidney disease
- Diabetes monitoring — annual screening for proteinuria/microalbuminuria is recommended for all diabetics
- Hypertension — proteinuria screening to check for kidney involvement
- Pregnancy — routine at every antenatal visit to screen for preeclampsia (protein) and UTI (pus cells, nitrites)
- Pre-surgical evaluation — standard before most surgeries
- Unexplained fever — to rule out urinary source of infection
For diabetics and hypertensives: Even if your routine urine dipstick is normal, request an annual UACR test. Early detection of microalbuminuria can delay or prevent progression to kidney failure with timely treatment.
How Urine Tests Connect to Your Other Reports
Your urine report does not exist in isolation. Here is how it links to other tests:
- KFT (Kidney Function Test): Protein and casts in urine + elevated creatinine/low eGFR = confirmed kidney disease. Urine abnormalities often appear before blood markers change
- HbA1c: Glucose in urine + HbA1c >7% = poorly controlled diabetes needing treatment intensification. Microalbuminuria + elevated HbA1c = diabetic nephropathy developing
- CBC: Elevated WBC count on CBC + pus cells in urine = systemic response to urinary infection
- LFT (Liver Function Test): Bilirubin in urine + elevated serum bilirubin on LFT = obstructive jaundice or liver disease
- Uric Acid: Uric acid crystals in urine + elevated serum uric acid = increased risk of uric acid kidney stones
When you upload all your reports to MedicalVault, the app creates a unified view across blood and urine markers, helping you and your doctor connect the dots that individual reports might miss. Use the family sharing feature to manage urine and blood reports for elderly parents or family members with chronic conditions.
Key Takeaways
- The urine routine and microscopy test is a three-part analysis — physical (colour, clarity), chemical (dipstick for pH, protein, glucose, blood, nitrites, ketones), and microscopic (pus cells, RBCs, crystals, casts, bacteria)
- Pus cells >5/HPF with positive nitrites and leukocyte esterase is the classic UTI pattern — but always get a urine culture for recurrent infections, especially given India's high antibiotic resistance rates
- Protein in urine is an early kidney damage signal — it can appear years before your KFT shows abnormalities. Diabetics should get an annual UACR test even if the dipstick is negative
- Crystals in urine warn of kidney stone risk — India sits in the global stone belt. Stay hydrated (2.5-3L/day), add nimbu to water, and moderate oxalate-rich foods like palak and chiku
- Proper mid-stream clean-catch collection is essential for accurate results — contaminated samples lead to false positive bacteria and excess epithelial cells
- Never self-medicate UTIs with antibiotics — antibiotic resistance in India is a growing crisis. Always consult your doctor and complete the full course
- Track your urine results over time on MedicalVault alongside your blood reports for a complete picture of your kidney, liver, and metabolic health
