Case Study: Dark Urine after Strep Throat Answers



3. The cell that is shown is a squamous epithelial cell.  This cell is not pathological and has a reference range of 0-5/hpf.  Squamous epithelial cells appear in the urine if the patient does not clean properly prior to collection.  Improper cleansing can cause a squamous epithelial cell level higher than the reference range; however, squamous cells are only pathological if found in sheets in the urine which could indicate squamous cell carcinoma.  However, this cancer is very rare.
      In order to avoid squamous cells in the urine, the patient should clean with soap and water before urinating then collect a mid-stream sample.  This means that the patient should void a little bit into the toilet then collect the rest in the provided sample cup.  This ensures that the urine that is collected is from the bladder and is not contaminated or contain formed elements that are not indicative of disease.
