A laboratory total hemoglobin (tHb) measurement, from venous blood sampling, was obtained immediately prior to the SpHb measurement. The total number of measurements obtained from the nonpregnant, pregnant, and postpartum women was 76, 438, and 347, respectively.Results: The mean biases (SpHb - tHb) among the nonpregnant, first trimester, second trimester, third trimester, and early postpartum women were -0.20, 0.19, 1.01, 1.32, and 1.10 g/dL, respectively. The Bland-Altman comparison showed neither the tendency of a fixed bias nor proportional biases among the measurements in the category of nonpregnant and first trimester women. But in the second and third trimester and postpartum category, a significant fixed bias was noted, without any tendencies of proportional bias.Conclusion: In this study, we found higher hemoglobin values with the Pronto-7 analyzer than were measured in the laboratory. We consider that the device has certain limitations in obstetrical utility and requires further modifications for use in the perinatal period.Keywords: anemia, pregnancy, hemoglobin, noninvasiveYoshida ASaito KIshii KAzuma ISasa HFuruya KDove Medical PressarticleMedical technologyR855-855.5ENMedical Devices: Evidence and Research, Vol 2014, Iss default, Pp 11-16 (2014)
