Obtain clean catch specimen OR cath UA
Neg UA = neg LE, nit, GS & <5 WBC
Bag urine results in 83% false positive; only useful if negative
UTI diagnosis cannot be established reliably through bag urine culture (Evidence A; strong recommendation; AAP 2011)
Urine culture
Send on all patients except for:
1. Low-risk patients with normal UA and another explanation for symptoms
2. Older adolescent females with very high post-test probability without severe illness
20% of +Urine culture will have negative UA
Do not send urine bag specimen for culture when UA is negative and clinical suspicion is relatively low
False positives are high due to bag contamination
