Is a blood sample for hemoglobins in the transfusional range reliable
2018
Abstract Objective To evaluate the correlation and agreement in our unit and population of hemoglobin in gasometry versus hematology analyzer, to evaluate errors in transfusion or lack thereof. Results strong association between Point-of-care (POC) and hematimetry, with P r 2 of 0.56, an intraclass correlation coefficient of 0.63 and a Lin's concordance correlation coefficient of 0.65. For hemoglobins less than 7 g/dL, a success rate of 29.41% was obtained. Conclusions Low-moderate agreement of POC hemoglobin with standard haemothymetry. High probability of errors in the indication of transfusion based on gasometer hemoglobins, especially in low hemoglobins.
