When choosing a chemistry analyzer for a pediatric laboratory, it is necessary to

• A. Be able to analyze from small volumes
• B. Have rapid turnaround
• C. Have an extensive menu
• D. Have front-end automation

Answer: (A)

In pediatrics, blood volume is precious, especially in newborns and small children. The most critical need for a chemistry analyzer in a pediatric lab is the ability to analyze from small sample volumes. Many tests must be run on micro-volume specimens or even capillary/heel-stick samples, so an analyzer that can accurately measure chemistry parameters with minimal blood draws directly reduces the need for repeat sticks, lowers the risk of iatrogenic anemia, and supports safer, more patient-friendly testing. While rapid turnaround, an extensive test menu, and front-end automation are beneficial for overall workflow and versatility, they don’t address the central constraint in pediatric testing—the limited amount of blood that can be collected. Therefore, the essential requirement is capability to work with small volumes.
