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:

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.
