What does high Hgb mean in kids?
By Mayo Clinic Staff. A high hemoglobin count indicates an above-normal level of the iron-containing protein in red blood cells.
What happens if Hgb count is high?
High Hgb is known as polycythemia. This means you have too many red blood cells. Polycythemia vera is a cancer of the blood in which your bone marrow overproduces red blood cells. With polycythemia, a blood test also shows that you have a high red blood cell count and high hematocrit.
What would cause Hgb to be high?
A high hemoglobin count occurs most commonly when your body requires an increased oxygen-carrying capacity, usually because: You smoke. You live at a high altitude and your red blood cell production naturally increases to compensate for the lower oxygen supply there.
Why would a child have a high red blood count?
Medical conditions that can cause an increase in red blood cells include: Heart failure, causing low blood oxygen levels. Congenital heart disease (“congenital” means you’re born with it). Polycythemia vera (a rare blood cancer in which your bone marrow produces too many red blood cells).
Do children get polycythemia?

When should you suspect polycythemia vera?
