Final answer:
A urinalysis is the most appropriate initial lab test for a male patient with urinary hesitancy and a sensation of incomplete bladder emptying. While CBC, LFTs, and Lipid Panels have their purposes, they are not the primary tests for urinary issues.
Step-by-step explanation:
For a male patient experiencing urinary hesitancy and a feeling of incomplete bladder emptying, a urinalysis is typically the first lab test ordered. This simple screening involves examining a urine sample for color, odor, appearance, and concentration. The chemical analysis looks for substances such as protein, glucose, and pH, while the microscopic analysis checks for red blood cells, white blood cells, epithelial cells, bacteria, and crystals. If the urinalysis indicates a disease or impaired kidney function, further tests, including a urine culture or additional blood tests to assess renal function, may be performed. Tests such as Complete Blood Count (CBC), Liver Function Tests (LFTs), and a Lipid Panel, while useful for other diagnoses, are not typically the first line of investigation for urinary complaints.
