<p><b>New page</b></p><div>==Background==<br />
*Oxygen-carrying protein in red blood cells<br />
*Reported on [[CBC]]; hemoglobin and hematocrit move in parallel<br />
<br />
==Normal Values==<br />
*Male: 13.5-17.5 g/dL<br />
*Female: 12.0-16.0 g/dL<br />
<br />
==Interpretation==<br />
*Low hemoglobin (anemia): blood loss, hemolysis, decreased production, or dilution<br />
*In acute hemorrhage, hemoglobin may be initially normal (dilution has not yet occurred); it does not drop until volume equilibration over 6-24 hours<br />
*Transfusion threshold in most ED patients: Hgb <7 g/dL; consider <8 g/dL for active coronary syndrome<ref>Carson JL, et al. Clinical practice guidelines from the AABB: red blood cell transfusion thresholds and storage. JAMA. 2016; 316(19):2025-2035. PMID 27732721.</ref><br />
*Elevated hemoglobin (polycythemia): dehydration, chronic hypoxia, polycythemia vera<br />
