Study Notes

Symptoms and Conditions of Blood Disorders

Common symptom of anemia includes fatigue, weakness, and pallor.
Polycythemia vera is primarily caused by a mutation in the JAK2 gene, leading to excessive red blood cell production.
Sick cell disease is characterized by an abnormal shape of hemoglobin, leading to various complications.
Leukocytes, or white blood cells, primarily function in the body's immune response to fight infections.

Leukocyte and Platelet Abnormalities

Decreased leukocyte count defines leukopenia, resulting in increased susceptibility to infections.
Normal platelet count ranges from 150,000 to 450,000 platelets per microliter of blood.
Thrombocytosis indicates an abnormally high platelet count, which can increase the risk of clotting.
Main symptom of thrombocytopenia is excessive bleeding or easy bruising.

Crisis Conditions and Hematologic Features

Sickle cell crisis involves a series of pain episodes often triggered by illness or stress.
Anemia is characterized mainly by symptoms of fatigue and weakness during exertion due to reduced oxygen delivery.
Common symptoms associated with hematologic disorders include shortness of breath and abnormal bleeding.

Reference Values for Blood Components

Normal hematocrit range for males is approximately 40% to 54%.
Oxygen is primarily carried by red blood cells (erythrocytes) due to the presence of hemoglobin.
Normal leukocyte count ranges from 4,500 to 11,000 leukocytes per microliter of blood.
Normal range for hemoglobin is 12 to 16 g/dL in females, reflecting healthy oxygen transport capacity.

Additional Considerations

Pernicious anemia commonly presents with symptoms such as weakness and neurological changes due to Vitamin B12 deficiency.
Post-surgical patients and those who are immobilized face the risk of thromboembolism, particularly due to low mobility.
