Which test is commonly performed using venipuncture?

• A. Blood Cultures
• B. Lipids Panels
• C. CBC
• D. Urine hCG

Answer: (C)

Venipuncture is the standard way to obtain a clean blood sample from a vein for most routine hematology tests. The complete blood count relies on a sample of whole blood drawn from a vein and preserved with EDTA to keep the cells intact for accurate counting and measurement of red cells, white cells, and platelets. Because CBC is such a fundamental, commonly ordered test in virtually every clinical scenario, it is most frequently performed using venipuncture. Urine hCG, by contrast, is measured in urine, not blood, so it isn’t obtained via venipuncture. Lipid panels and blood cultures can also be drawn by venipuncture, but a CBC is the quintessential example of a test routinely done this way.
