Eosinophils, Random, Urine
Use
The test is used for the investigation of possible acute interstitial nephritis, a condition often caused by an allergic reaction, typically to drugs. Eosinophils are a type of white blood cell that typically do not appear in urine; their presence is indicative of an inflammatory process within the kidneys.
Special Instructions
If not ordering electronically, complete, print, and send a Renal Diagnostics Test Request (T830) with the specimen.
Limitations
The test cannot be performed if there are no white blood cells present in the urine sediment. Only an unstained slide will be accepted; any other specimens, including raw urine, will be rejected.
