Capillary puncture is particularly beneficial for which patient group?

• A. Adults with stable veins
• B. Pediatric patients
• C. Patients with obesity
• D. Elderly with large veins

Answer: (B)

Capillary puncture is particularly useful in pediatric patients because their veins are often small, difficult to locate, and they may be uncooperative, making venipuncture challenging. A finger or heel prick uses a very small blood sample, which minimizes discomfort and the amount of blood needed, while still allowing rapid, point‑of‑care testing for many screening or laboratory needs. In adults with stable veins, or in patients with obesity or elderly individuals with readily accessible veins, venipuncture is usually straightforward and capillary sampling is not as advantageous, since some tests require larger volumes or can be affected by the mix of capillary and tissue fluids.
