Q. A 45-year-old man presents to the clinic with concerns about noticing a faint pinkish tinge in his urine for the past week. He denies any symptoms of pain during urination, flank pain, recent trauma, or any other urinary symptoms. His past medical history is unremarkable, and he is not on any medications. On physical examination, there are no palpable masses, and the abdominal and renal examinations are non-contributory. Urinalysis with a dipstick test shows positivity for heme. A microscopic urinalysis confirms the presence of four red blood cells (RBCs) per high-power field. What is the most appropriate initial management for this patient?
