Use of non-invasive total hemoglobin measurement as a screening tool for anemia in children

Area of Science:

• Pediatric Medicine
• Medical Devices
• Diagnostic Technology

Background:

• Universal anemia screening in children is crucial but often requires invasive blood sampling.
• Non-invasive hemoglobin measurement devices aim to simplify this process.
• The clinical utility of the Radical-7® Pulse CO-Oximeter™ for pediatric anemia screening remains to be fully established.

Purpose of the Study:

• To evaluate the effectiveness of the Radical-7® Pulse CO-Oximeter™ for non-invasive hemoglobin concentration (SpHb) measurement in children.
• To compare SpHb readings with results from a standard complete blood count (CBC) analysis.
• To assess the feasibility of using SpHb as a primary screening tool for anemia in pediatric populations.

Main Methods:

• SpHb measurements were performed using the Radical-7® Pulse CO-Oximeter™ during routine medical check-ups for 110 three-year-old children.
• A separate cohort of 43 pediatric patients underwent both CBC analysis using a Microsemi® hematology analyzer and Radical-7® monitoring.
• Statistical analysis included correlation and Bland-Altman comparison to assess agreement between SpHb and CBC.

Main Results:

• The mean SpHb level in the 3-year-old cohort was 12.1 ± 0.64 g/dL.
• A significant correlation (r=0.602, P < 0.0001) was observed between Radical-7® SpHb and Microsemi® CBC results.
• Bland-Altman analysis indicated a bias of -0.6 ± 1.1 g/dL between the two measurement methods.

Conclusions:

• The Radical-7® Pulse CO-Oximeter™ demonstrates potential as a non-invasive tool for initial anemia screening in children.
• While the device shows promise, further improvements are necessary to enhance accuracy and reliability.
• Non-invasive SpHb measurement offers a viable alternative for primary screening, potentially reducing the need for invasive procedures.
