Dysmorphic RBC, Urine

Dysmorphic RBC, Urine

Overview
The Dysmorphic RBC, Urine test evaluates the shape and appearance of red blood cells (RBCs) present in urine. Identifying abnormally shaped RBCs can help determine whether blood in the urine may be originating from the kidney glomeruli.

Test Name: Dysmorphic RBC, Urine
Sample Type: Urine
Method: Microscopic examination / Urine sediment analysis

Why is this test done?

• Evaluation of hematuria (blood in urine)
• Helps differentiate glomerular from non-glomerular sources of RBCs
• Assessment of possible glomerular kidney disorders
• May be useful alongside urine protein, creatinine, and other renal investigations

Clinical Significance
Dysmorphic RBCs, particularly characteristic forms such as acanthocytes, may suggest a glomerular source of hematuria. More uniformly shaped (isomorphic) RBCs are more commonly associated with bleeding from the urinary tract below the glomerulus.

Sample Requirements
A fresh, properly collected urine sample is preferred. Follow the laboratory's instructions for collection and transport.

Note: RBC morphology should be interpreted together with urine findings, clinical symptoms, and other kidney function investigations. A single result does not establish a diagnosis.
