Abstract

The Astrim system (Sysmex Co.) can measure hemoglobin concentrations in a noninvasive manner using the near-infrared spectroscopic imaging method. We measured the hemoglobin concentration of 258 applicants for blood donation using the Astrim and conventional methods at the same time. Results showed a good correlation between concentrations measured by Astrim and the conventional methods at an ambient atmospheric temperature between 22°C and 26°C (202 applicants). In this condition, there was a good correlation between the ability to donate blood as determined by Astrim and that by conventional methods. However, at ambient temperatures below 20°C (56 applicants), hemoglobin concentration could not be obtained correctly by Astrim as has been reported previously. ROC analysis revealed that noninvasive hemoglobin concentration measurement can determine the ability of blood donation in about half of cases. In conclusion, noninvasive hemoglobin concentration measurement by Astrim is a useful method for blood donor selection. This noninvasive method can avoid the side effects of needle stick such as VVR or nerve injury.<br>
