Final answer:
Polycythemia vera is a bone marrow disease that causes an excessive production of immature erythrocytes. Some markers associated with polycythemia vera include erythropoietin (EPO) and JAK2 mutation. These markers can help diagnose and differentiate polycythemia vera from other causes of polycythemia.
Step-by-step explanation:
Polycythemia vera is a bone marrow disease that causes excessive production of immature erythrocytes, resulting in an elevated red blood cell count. This disease can be detected through a patient's elevated hematocrit. Polycythemia vera is associated with certain markers that can be found in the blood. These markers include erythropoietin (EPO) and JAK2 mutation. EPO is a hormone that stimulates the production of red blood cells, and its elevated levels can indicate polycythemia vera. JAK2 mutation is a genetic mutation that is present in the majority of cases of polycythemia vera. Detecting these markers can help diagnose polycythemia vera and differentiate it from other causes of polycythemia.
