What does this LOINC code represent?

This LOINC code identifies a lab observation, measurement, question, or clinical concept in a standardized format.

Is this enough to understand my test result?

No. The code identifies the test or observation, but the interpretation depends on the actual result, reference range, and clinical context.

Key facts

Acanthocytes [Presence] in Urine sediment by Light microscopy

Acanthocytes

Acanthocytes are a type of dysmorphic red blood cell (RBC) with vesicle-shaped protrusions. The presence of acanthocytes in urine sediment is indicative of glomerular pathology. Although hematuria is common in diabetic nephropathy, acanthocytosis is not; therefore, patients with diabetic nephropathy who are found to have acanthocytes in their urine sediment should have further work-up to determine the etiology of glomerular disease.
