Eosinophiluria

Eosinophiluria is the abnormal presence of eosinophils in the urine.

It can be measured by detecting levels of eosinophil cationic protein.^[1]

Associated conditions

It can be associated with a wide variety of conditions, including:

• urinary tract infection
• kidney disorders such as acute interstitial nephritis{{http://www.nejm.org/doi/full/10.1056/NEJMc0708475}}
• Churg-Strauss syndrome^[2]
• atheroembolic acute kidney injury

Eosinophiluria (>5% of urine leukocytes ) is a common finding (~90%) in antibiotic induced allergic nephritis, however lymphocytes predominate in allergic interstitial nephritis induced by NSAIDs. eosinophiluria is a feature of atheroembolic ARF. In PAN,microscopic polyangitis, eosinophiluria is rare.
