Hematocrit levels for polycythemia
WebHämoglobin ist ein globuläres Protein mit sehr guter Löslichkeit in Wasser (Löslichkeit bis zu 5 mmol/l Hämoglobin (34 %)). 1 g Hb kann in vitro 1,389 ml Sauerstoff binden, in vivo jedoch nur 1,34 ml (Hüfnersche Zahl), somit können 100 ml Blut, die etwa 15 g Hb enthalten, bei 100-prozentiger Sättigung bis zu 15 × 1,34 ml = 20,1 ml Sauerstoff aufnehmen. Web2 dec. 2016 · The mean hemoglobin at all donor clinic visits was 173 g/L (range 134-205 g/L, n = 108). Hemoglobin concentrations of ≥180 g/L (calculated hematocrit ≥54%) were measured at 25% of appointments. Of the 27 repeat donors, 12 (44%) had persistently elevated hemoglobin levels (≥180 g/L) at subsequent donations.
