- W4293244015 abstract "INTRODUCTION: Noninvasive hemoglobin analyzers measure hemoglobin percutaneously and offer the benefit of a one-time spot check without phlebotomy. The objective of this study was to determine the validity of noninvasive hemoglobin testing for detection of postpartum anemia (hemoglobin <10 g/dL). METHODS: A convenience sample of 584 women aged 18 and over were recruited on postpartum day 1 following a singleton delivery. Two noninvasive hemoglobin monitors, Masimo Pronto Pulse CO-Oximeter (Pronto) and Masimo Rad-67 Pulse CO-Oximeter (Rad-67), were evaluated and compared to the postpartum phlebotomy hemoglobin value. RESULTS: Of 584 participants, 31% (181) had postpartum anemia by phlebotomy hemoglobin measurement. Bland-Altman plots determined a positive bias of 2.4 (±1.2) g/dL with the Pronto and 2.2 (±1.1) g/dL with the Rad-67. Low sensitivity was observed: 15% for Pronto and 16% for Rad-67. Adjusting for the fixed positive bias, the Pronto demonstrated a sensitivity of 68% and specificity of 84%, while the Rad-67 demonstrated a sensitivity of 78% and specificity of 88%. CONCLUSION: A consistent overestimation of hemoglobin by the noninvasive monitors compared to phlebotomy hemoglobin result was observed. Even after adjusting for the fixed positive bias, the sensitivity for detecting postpartum anemia was low. Detection of postpartum anemia should not be based on these devices alone." @default.
