Measurement of hemoglobin on site?
As you know an HbNO measurement will be performed at baseline, 6 and 12 months. These timepoints also match with the CMR timepoints. As requested by the CMR corelab of UOXF, a local measurement of hematocrit is needed. As this measurement has to be performed on a whole blood fraction just like the measurement of hemoglobin, could you also measure the hemoglobin on site (along with the hematocrit) for avoiding the shipping and measurement of hemoglobin on an unstable frozen whole blood fraction?
Thank you in advance for your confirmation.
