Renal Epithelial Cells (Urine)
Renal tubular epithelial cells line the kidney tubules and are normally absent or very rare in urine. Their presence suggests tubular injury from acute tubular necrosis, nephrotoxic drugs, heavy metal exposure, or viral infection. Large numbers or renal tubular casts signal significant kidney damage and prompt further evaluation of kidney function.

Why Renal Epithelial Cells (Urine) matters
These cells line the kidney tubules. Their presence may indicate kidney tubular damage from conditions like acute tubular necrosis, nephrotoxic drugs, or viral infections affecting the kidneys.
Which Providers Test Renal Epithelial Cells (Urine)?
Empirical Health is both the cheapest ($190/year) and the most comprehensive (100+ biomarkers) panel that includes Renal Epithelial Cells (Urine).
2 panels that include it, cheapest first
| Provider | Annual Cost | Total Biomarkers | $/Biomarker |
|---|---|---|---|
| $190 | 100+ | $1.90 | |
| $365 | 100+ | $3.65 |
$/Biomarker is annual cost divided by the panel's advertised biomarker count, not the price of this one test. We track 23 blood test providers (32 plans); 21 of those plans are itemized marker by marker. Compare all of them.
