Question

Quizplus · Accepted Answer

Neonatal screening samples are usually collected by dermal puncture (a.k.a heel stick or finger stick) and absorbed onto filter paper. This is a less invasive method than routine venipuncture and requires only a small amount of blood from the infant. Option B (dermal puncture into a microtainer) is also a possibility, but not as commonly used as filter paper. Option C (routine venipuncture) and option D (venipuncture with butterfly needle and syringe) are not considered appropriate for neonatal screening as they are more invasive and require larger volumes of blood.
