Information about a laboratory test
The Urinary Casts test assesses tube-shaped casts and their types seen on urine microscopy.
The Urinary Casts test assesses tube-shaped casts and their types seen on urine microscopy.
It is used to provide microscopic context about renal tubular and glomerular processes.
Cellular casts are generally absent; a few hyaline casts may be seen in some healthy people.
The cast type is often more informative than the count; RBC, WBC, granular and other casts can be associated with different renal processes.
Start with the performing laboratory's reference interval, method, collection conditions and reporting unit. Urinalysis findings do not establish a diagnosis on their own.
Sourced reference context for Urinary Casts
This is sourced example reference/clinical-context information; the user's own laboratory report and specimen conditions take priority.
Reference ranges may vary by laboratory, method used, age, sex, pregnancy status, and clinical context. The reference range on your own laboratory report takes precedence.
