Overview
Blood tests
About 23% of patients have eosinophilia[1].
Urinary findings
Urinary findings include:
- Eosinophiluria: sensitivity is 67% and specificity is 83% [2][3]. The sensitivity is higher in patients with interstitial nephritis induced by methicillin or when the Hansel's stain is used.
- Isosthenuria [4]
Gallium scan
The sensitivity of an abnormal gallium scan has been reported to range from 60%[5] to 100%[6].
