9. Which hormone, secreted by the kidney, is responsible for increased production of red blood cells? Erythropoietin
Erythrocyte Sedimentation Rate (ESR)
10. Sickled red blood cells have an abnormal shape and do not tend to form stacks of cells (rouleaux formation). This would ( increase / *decrease ) the sedimentation rate. 11. Is the ESR test a specific test used to diagnose a disease? No
