Urine Report Kaise Parhein: Pus Cells, Protein, Sugar, Blood

Pus cells 0 to 5 per HPF is the range most labs print as normal; a higher count means white cells are in the sample, which can be an infection but is very often a badly collected or stale sample. Here’s how to read the whole urine R/E sheet, section by section, and what to ask before anyone reaches for a prescription.

Urine R/E (routine examination) is the cheapest test in the lab and one of the most misread. A single line in bold, “pus cells 20 to 25”, sends people straight to the chemist. Slow down. The sheet has three parts, and they only make sense together.

What a urine report checks: the three sections

Every R/E report follows the same order. First the lab looks at the urine (physical). Then it dips a strip with coloured pads into it (chemical). Last, it spins a little in a centrifuge and looks at the sediment under a microscope (microscopy).

Ranges below are the ones widely printed for adults. Your lab’s printed range on the report wins, and children, pregnancy and women during a period all read differently.

Physical: colour and appearance

Pale straw to amber is normal, and the shade mostly tracks how much water you drank. “Turbid” or cloudy can mean white cells or bacteria, but also harmless phosphate crystals that settle when urine cools. Red or cola-coloured urine should be seen the same day, even though beetroot and some medicines can tint it.

Chemical: the dipstick lines

Microscopy: cells, casts, crystals

• Pus cells (WBC): usually 0 to 5 per HPF (high-power field, the patch of sample seen at one time under the lens).
• RBC: usually 0 to 2 per HPF.
• Epithelial cells: “few” is normal. “Many” squamous epithelial cells mean skin cells washed in from outside, a contamination signal.
• Casts: tiny tube-shaped moulds from the kidney. Hyaline casts after exercise are common; other types deserve a doctor’s look.
• Crystals: oxalate or urate crystals are frequent in concentrated urine and aren’t, on their own, a stone.
• Bacteria: “occasional” is common in samples left standing.

Pus cells in urine: normal range, 20 to 25, and “plenty”

This is the line everyone searches. The honest answer has three parts.

0 to 2 or 0 to 5: normal on almost every lab’s sheet.

10 to 25: raised. With burning, urgency, fever or back pain, the doctor takes it seriously. Without any symptoms, and especially with “many epithelial cells” printed below it, the commonest explanation is a sample that picked up cells from the skin or vaginal discharge on the way into the cup.

“Plenty”, “numerous” or “field full”: far more likely to be real, but still read with symptoms and, often, a culture.

A raised count also isn’t proof of which germ, or whether any germ at all. That job belongs to a urine culture, which grows the sample and names the organism. The R/E only raises the question; the culture answers it. For the symptoms side of the story, see when burning urination needs a test.

How to give a clean-catch sample (it changes the result)

1. Collect the first urine of the morning if the lab allows it, because it’s more concentrated.
2. Wash hands. Wash the genital area with plain water from front to back, and pat dry. No antiseptic, which can kill germs the lab needs to see.
3. Women: hold the labia apart with one hand throughout. Men: pull back the foreskin if present.
4. Pass the first few seconds into the toilet. Then, without stopping, catch the middle part in the sterile cup, filling it about halfway (roughly 20 to 30 ml).
5. Finish in the toilet. Close the lid without touching the inside.
6. Deliver it to the lab within 1 hour, or keep it in a fridge (not the freezer) for up to about 4 hours.
7. Avoid testing during a period if you can; if you can’t, tell the lab.

High protein in urine: what the line means

A dipstick “trace” or “+” of protein after fever, a long day on your feet or a hard workout is common and often vanishes on repeat. Persistent protein is different, particularly with diabetes or high blood pressure. The dipstick is crude, so doctors confirm with a spot urine albumin to creatinine ratio (ACR), explained in our creatinine, eGFR and ACR guide.

In pregnancy, protein with headache, blurred vision or swelling of the face and hands is a same-day problem, because it can signal high blood pressure of pregnancy.

Sugar, ketones and blood in the urine report

Glucose spills into urine when blood sugar climbs above roughly 180 mg/dL, the kidney’s usual threshold, though pregnancy lowers that threshold. So urine sugar is a hint to check blood sugar, never a diagnosis. Sugar plus ketones together, especially with thirst, vomiting or fast breathing, needs a doctor the same day.

Blood on the strip with no red cells under the microscope can come from muscle breakdown after very hard exercise. Blood you can see with your own eyes always needs a doctor, whether or not it hurts.

Did you know?

• A big dose of vitamin C in drinks or tablets can hide sugar and blood on the dipstick, giving a falsely clean result.
• Urine left at room temperature for a few hours lets bacteria multiply in the cup, so an old sample can look infected when the bladder isn’t.
• Crystals often form after the sample cools, in the cup, rather than in your body.

Myth: pus cells in urine always mean you need an antibiotic

They don’t. Guidelines in many countries advise against treating white cells or bacteria found in urine when a person has no symptoms, except in pregnancy and before some urology procedures. Antibiotics taken without a real infection feed resistance, which is already a serious problem in Pakistan and India. The decision belongs to your doctor, and the culture usually guides it.

What moves the numbers, and questions to ask

Dehydration concentrates everything. A period adds blood. Exercise adds protein and blood. Fever adds protein. A late sample adds bacteria. Frequent passing of urine has its own list of causes, covered in bar bar peshab aana.

• Was my sample contaminated, given the epithelial cells?
• Should I repeat it as a proper clean-catch sample, and when?
• Do I need a urine culture before anything is started?
• Is the protein line worth an ACR test?
• Does the sugar line mean I should check my blood sugar?
