What causes epithelial cells in a urinalysis?

The most common cause of epithelial cells in urine is improper urine sample collection. Your doctor may, therefore, ask you to take another urine test. The presence of epithelial cells in urine may indicate infections, kidney disease, or (very rarely) a serious illness such as a tumor.

How many epithelial cells in urine is contaminated?

It’s normal to have one to five squamous epithelial cells per high power field (HPF) in your urine. Having a moderate number or many cells may indicate: a yeast or urinary tract infection (UTI) kidney or liver disease.

What does it mean when your urinalysis is contaminated?

If the urine is not collected in a sterile manner the urine sample may be ‘contaminated’ by bacteria that originate from the skin or genital area, and not from the urinary tract. This is often described by the clinical laboratory as ‘mixed growth bacteria’.

What is the definition of contamination in routine urine cultures?

Contamination: If a culture shows growth of several different types of bacteria, then it is likely that the growth is due to contamination. This is especially true in voided urine samples if the organisms present include Lactobacillus and/or other common nonpathogenic vaginal bacteria in women.

Is it normal to have leukocytes in urine?

If you’re healthy, you can still have elevated leukocytes in your bloodstream and urine. A normal range in the bloodstream is between 4,500-11,000 WBCs per microliter. A normal range in the urine is lower than in the blood, and may be from 0-5 WBCs per high power field (wbc/hpf).

How do you tell if a urinalysis is contaminated?

A contaminated urine specimen can give a large amount of false data on a dipstick test. Greater than five epithelial cells on microscopic evaluation is likely a sign of contamination.

How do you know if a urine culture is contaminated?

Definition of contamination Generally, UTI is suspected if culture counts of a pure or predominant growth of organism are ≥ 105 CFU/ml. Any counts below this with ≥ 2 organisms present may be indicative of contamination.

What are the common cause of errors encountered in urinalysis?

Routine urinalysis remains a fundamental tool to alert healthcare providers to the presence of renal damage and/or urinary tract disease. However, discrepancies between routine urinalysis and microscopy or patient history may occur due to physiological factors, medications, or collection issues.

Are squamous epithelial cells a good predictor of urine culture contamination?

Conclusions: Squamous epithelial cells are a poor predictor of urine culture contamination, but may predict poor predictive performance of traditional urinalysis measures. © 2016 by the Society for Academic Emergency Medicine. Academic Medical Centers Adult Age Factors Aged

Why would my doctor order epithelial cells in urine test?
