PY - 2007 T2 - Clinician's Pocket Reference: The Scut Monkey, 11e AB - For routine urinalysis, a fresh (less than 1-h old), clean-catch urine sample is acceptable. If the analysis cannot be performed immediately, refrigerate the sample. (When urine stands at room temperature for a long time, casts and red cells undergo lysis, and the urine becomes alkalinized with precipitation of salts.) See Chapter 13, Urinary Tract Procedures, for sample collection. SN - PB - The McGraw-Hill Companies CY - New York, NY Y2 - 2024/04/24 UR - accessmedicine.mhmedical.com/content.aspx?aid=2700536 ER -
