Sickle cell anemia is precipitated when:
1) Oxygen tension goes down
2) Increased viscosity of blood is there
3) There is dehydration
4) All of the above
Pathology Answer: 4
Sickle cell disease results from mutation, or change, of certain types of hemoglobin chains in red blood cells (the beta hemoglobin chains).
When the oxygen concentration in the blood is reduced, the red blood cell assumes the characteristic sickle shape. This causes the red blood cell to be stiff and rigid, and stops the smooth passage of the red blood cells through the narrow blood vessels.
