Epithelial Cells at 7.96 on Urinalysis: Clinical Significance
An epithelial cell count of 7.96 on urinalysis is a normal finding that requires no specific action, as epithelial cells are routinely shed from the urinary tract and their presence in this range does not indicate disease.
Understanding Epithelial Cells in Urine
Epithelial cells are structures regularly observed during urine microscopy analysis and are normally present in urine specimens 1. These cells originate from different parts of the urinary tract and are classified into three main subtypes:
- Squamous epithelial cells: Originate from the distal urethra and external genitalia, most commonly seen in urine specimens 2
- Transitional epithelial cells: Originate from the bladder, ureters, and renal pelvis 3
- Renal tubular epithelial cells (RTECs): Originate from the kidney tubules and are the only subtype with significant clinical relevance 2, 3
Clinical Significance of Your Result
Your value of 7.96 epithelial cells falls within the normal range for routine urine specimens. The majority of urine samples contain epithelial cells, with studies showing that 89% of samples contain both transitional and squamous populations 4.
The presence of squamous epithelial cells in moderate numbers does not indicate:
- Urinary tract infection 5
- Urine culture contamination (contrary to common belief) 5
- Kidney disease 2
- Any pathological condition requiring treatment 1
When Epithelial Cells Matter Clinically
Only renal tubular epithelial cells (RTECs) have clinical significance, as they may indicate:
- Upper urinary tract infection or pyelonephritis 3
- Acute tubular necrosis in acute kidney injury 2
- Other kidney parenchymal disease 2
However, RTECs are specifically identified and reported separately from general "epithelial cells" on urinalysis reports 1, 2. If your report simply states "epithelial cells" without specifying RTECs, these are almost certainly squamous or transitional cells, which are clinically insignificant 2.
Common Pitfalls to Avoid
Do not assume epithelial cells indicate contamination or poor specimen collection. While squamous cells were historically thought to predict urine culture contamination, research demonstrates they are a poor predictor of contamination (area under ROC curve = 0.680) 5. The presence of squamous epithelial cells does not accurately predict whether a urine culture will be contaminated 5.
Do not request repeat urinalysis or additional testing based solely on this finding. Epithelial cells in this range are expected in normal urine specimens and do not warrant further investigation 1, 4.
What You Should Do
No action is required for this finding alone 1, 5. Your epithelial cell count of 7.96 is a normal laboratory observation that does not indicate disease or require treatment.
However, if you have urinary symptoms (fever, dysuria, flank pain, frequency, urgency), these symptoms—not the epithelial cell count—should guide further evaluation 6. The presence of epithelial cells does not change the approach to symptomatic patients 5.
If other abnormalities are present on your urinalysis (such as hematuria ≥3 RBCs/HPF, significant pyuria, or proteinuria), those findings should be evaluated independently according to their own clinical significance 7, 8. The epithelial cell count does not modify the interpretation of these other findings 5.
