Transitional epithelial cells (also called urothelial cells) line the bladder, ureters, and part of the urethra. A small number shedding into the urine is normal as these cells naturally turn over. Increased numbers can appear with urinary tract infections, kidney stones, or recent instrumentation like catheterization. Rarely, abnormal-looking transitional cells can be a clue to a urinary tract tumor, which is why their appearance, not just their number, is noted. They are interpreted in the context of symptoms and the rest of the urinalysis.
Transitional Cells isn't sold on its own. It comes in a routine urinalysis, about $45. A fuller workup adds Vitamin D ($75), hs-CRP ($69), ApoB ($50), and ApoA1 ($50). You can test Transitional Cells and 100 other biomarkers for $190 as part of an Empirical membership.
Empirical is FSA/HSA eligible, so you can pay with pre-tax dollars. Fast for 8-12 hours beforehand for the most accurate lipid and metabolic results, and expect results in days rather than weeks.
