Epithelial Cells — What It Means in Your Urine Test
New to reading lab reports? Start with our guide to reading a blood test report
This looks at lining cells that shed into your urine, which often just reflect how the sample was collected.
Epithelial Cells are the everyday lining flakes that drift into your sample. Often their presence says more about how the specimen was gathered than anything happening inside you, so context matters here.
Also known as: Squamous epithelial cells (urine), Transitional cells (urine), Renal tubular epithelial cells, EC (urinalysis)
This isn't a case where higher or lower is better. Your body keeps it in a narrow band, and both directions can matter.

What is Epithelial Cells?
Epithelial cells are lining cells shed from your urinary tract or skin into the sample. The lab sorts them by type under the microscope.
Why is Epithelial Cells tested?
It is checked as part of routine microscopy. Many surface cells usually mean skin-cell mixing, while deeper lining cells can reflect the bladder or kidney tubes.
What is a normal Epithelial Cells range?
- India
- No India-specific national reference interval is published for this parameter; your lab's printed range is the most reliable comparison.
- Global
- Squamous: few (up to 5 per HPF acceptable; higher suggests contamination); Transitional: 0–2 per HPF; Renal tubular: rare/none
Ranges vary by lab, method and equipment — the range printed on your own report is the one that applies to your result.

What does your Epithelial Cells value mean?
There is no widely-accepted set of value bands for this parameter. Compare your result with the reference range printed on your own report, and discuss it with your doctor.
What does a high Epithelial Cells result mean?
Many surface (skin) cells usually mean the sample got mixed with skin cells, so it may need repeating with better technique. Raised deeper lining cells can reflect the bladder or kidney tubes.
What does a low Epithelial Cells result mean?
A low count is expected and is no cause for concern. A sample with no such cells at all is also normal.
What can affect your Epithelial Cells result?
- A clean mid-stream sample
- More common in women
- Collection method
- Timing and hygiene
- Recent urinary procedures
Questions to ask your doctor
About this result
- What does my Epithelial Cells result mean for me specifically, given my age and health?
- Is my Epithelial Cells in the range that is right for me, not just the lab's general range?
What to do next
- Could anything I eat, do, or take have affected my skin-like lining cells in urine result?
- Is there anything I should do about my Epithelial Cells, or is it fine to leave as it is?
About retesting
- Does my Epithelial Cells need to be repeated, and if so, when?
- The typical range for Epithelial Cells can vary between labs — should I compare my result against my own lab's printed range?
The bigger picture
- Should my Epithelial Cells be looked at together with my Urine pH and Urine Specific Gravity result?
- Does my Epithelial Cells connect to any condition I already have, or to anything I have noticed in how I feel?
