Which of the following is an advantage of capillary puncture?

• A. Good for pediatric patients
• B. Minimally invasive
• C. All of the above
• D. Requires small blood volume

Answer: (C)

Capillary puncture is advantageous because it uses a very small amount of blood, is less invasive than drawing from a larger vein, and is especially helpful in pediatric patients where venous access can be challenging. The small blood volume requirement is crucial when dealing with newborns or when multiple tests are needed from a single prick. Being minimally invasive reduces pain and distress for the patient and speeds up the sampling process. Importantly, these benefits together mean this technique is broadly advantageous, so the option that includes all of them best captures why capillary puncture is used.
