Question: what are the methods of collecting a urine specimen?
Answer: Diagnosis requires collection of urine generally by 1 of 4 methods: sterile urine bag, urethral catheterization (CATH), suprapubic aspiration (SPA), or clean-catch (CC). Both CATH and SPA are thought to yield the most reliable results by minimizing false-positive results, but these methods are invasive and painful.
