Eosinophiluria Explained

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:

• Kidney disorders such as acute interstitial nephritis^[2] and acute kidney injury from cholesterol embolism
• Eosinophilic granulomatosis with polyangiitis^[3]

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.
