Blood tests for leukemia typically show abnormal red blood cell counts, abnormal white blood cell counts, and abnormal platelet counts. There are no fixed values.
Leukemia has variable values at the time of routine blood tests. The main thing to look for is whether there are any primitive cells, the white blood cells are sometimes elevated, but sometimes they are really normal, and there may be a decrease, so it is not certain, and then the red blood cells usually drop when you go for a routine check, but if it is chronic leukemia the values are normal or elevated, and the platelets are reduced to varying degrees if it is acute leukemia. The most important thing is that the number of people who have been in the hospital for a long time is not as high as it should be.
Leukemia blood count abnormalities generally occur in a subset of people with leukemia who have increased white blood cells and in a subset of people who have normal white blood cell counts, with high white blood cell counts being called hyperleukocytic leukemia and low white blood cell counts being called hypoleukocytic leukemia. Patients with abnormal erythrocyte counts will have decreased erythropoietin at the onset of the disease. It is the degree of anemia that is determined based on the erythropoietin and the abnormal platelet count in the monthly routine test. The platelet count is decreased in patients with leukemia, but is increased in chronic granulocytic leukemia.
