Which test is not typically performed using venipuncture?

• A. CBC
• B. Lipid Panels
• C. Blood Cultures
• D. Urinalysis

Answer: (D)

Tests that analyze blood components—like cell counts, lipids, or detecting bacteria in the bloodstream—are done by drawing blood from a vein (venipuncture). A complete blood count uses blood cells in the sample; a lipid panel measures cholesterol and triglycerides in serum after a blood draw; blood cultures look for bacteria in blood by culturing the drawn blood. Urinalysis, however, examines urine's appearance, chemical properties, and sometimes microscopic components, which requires a urine sample collected separately from the patient (usually a clean-catch voided sample or, if needed, catheterization). Because urine collection is not obtained from veins, urinalysis is not typically performed using venipuncture.
