Dysmorphic RBC Detection in a spot urine sample is a microscopic test that examines the shape and appearance of red blood cells in urine. Abnormally shaped or dysmorphic RBCs may suggest that bleeding originates from the kidney’s glomeruli. The test is needed to help evaluate unexplained blood in urine (hematuria), distinguish glomerular from non-glomerular bleeding, and support the assessment of certain kidney disorders.
Dysmorphic RBCs are red blood cells with irregular shapes or appearances. Changes can occur when RBCs pass through damaged glomerular structures in the kidneys.
A significant proportion of dysmorphic RBCs may suggest glomerular bleeding, which can occur with certain kidney diseases. The finding should be interpreted with other urine and kidney tests.
Glomeruli are tiny networks of blood vessels in the kidneys that filter blood and help form urine. Damage to them can allow RBCs to enter the urine.
Yes. Finding dysmorphic RBCs can provide supportive evidence of glomerular involvement, although the test alone cannot diagnose a specific kidney disease.
