Cystine Crystals in Urine Sediment: Microscopy

Morphological features of cystine crystals in urine sediment: differentiating hexagonal plates from leukocytes and erythrocytes during microscopy.

Urine sediment microscopy: hexagonal cystine crystals, leukocytes, and erythrocytes
Urine sediment microscopy: hexagonal cystine crystals, leukocytes, and erythrocytes

🔬 Urine sediment microscopy. In the field of view, we see: ✅ Leukocytes: granulocytes, which do not have high refractile capacity and are larger than erythrocytes; ✅ Erythrocytes: small, anucleated, with a refractile halo. ✅ Cystine crystals: colorless, hexagonal plates, of variable thickness and weakly refractile.
