HEMATOLOGY is a branch of medicine involving study and treatment of the blood.
Hematology tests can be used to indicate, diagnose, and evaluate many conditions, including infection, inflammation, and anaemia. A complete blood count (CBC) measures
several components of the blood, including: White blood cells (WBC) - the body's primary defence system.
These include blood and bone marrow cells. Hematological tests can help diagnose anaemia, infection, haemophilia, blood clotting disorders, and leukaemia. One of the most common haematology tests is the complete blood count, or CBC.
This test is often conducted during a routine exam and can detect anaemia, clotting problems, blood cancers, immune system disorders and infections.
The three main types of blood cancer are Leukaemia, Lymphoma and Myeloma.
Leukaemia is a blood cancer that originates in the blood and bone marrow. Non-Hodgkin lymphoma is a blood cancer that develops in the lymphatic system from cells called lymphocytes, a type of white blood cell that helps the body fight infections.
Symptoms of blood disorders :
- Most commonly, symptoms are caused by decreases in the blood components. Decreased red blood cells and haemoglobin can cause symptoms of anaemia, such as
- fatigue, weakness, and shortness of breath. Decreased white blood cells or immune system proteins can cause recurrent fever and infections.
- Patients with CANCER, diagnosed or undiagnosed, are at risk for developing Blood Clots, which occur in 4% to 20% of patients. It is the second leading cause of death for these patients. It is important for patients, those with CANCER and those only affected by blood clots, to understand the connection between the two.
- Examples of blood tests used to diagnose CANCER include Complete blood count (CBC). This common blood test measures the amount of various types of blood cells in a
- sample of blood. Blood Cancers may be detected using this test if too many or too few of a type of blood cell or abnormal cells are found.
- Often the conditions that cause Erythrocytosis cannot be cured. Without treatment, Erythrocytosis can increase your risk for Blood clots, Heart attack, and Stroke. It can also increase your risk for Leukaemia and other types of Blood Cancers.
- It is a BLOOD CANCER that begins in the marrow of your bones, the soft centre where new blood cells grow. If you have Polycythaemia vera, your marrow makes too many red blood cells, which causes your blood to get too thick. That can make you more likely to have Clots, a Stroke, or a Heart attack.
- Blood Can Be Too Thin or Too Thick. Blood clots cause problems in the affected organ by cutting off oxygen flow. Thick blood is caused by heavy proteins, or by too much blood in the circulation. Too many red cells, white cells, and platelets will result in blood thickening.
