Hematology deals with diseases involving the blood, bone marrow and bleeding. It is a huge field with many different subspecialties.
Doctors who specialize in hematology examine blood smears under the microscope to check for abnormalities such as anemia, inflammation and blood cancers. They also treat patients with blood transfusions.
Blood is a vital fluid that provides nourishment to the entire body. It transports the proteins that make us healthy, controls clotting and bleeding abilities and helps us fight disease. Scientists and doctors who study the structure and function of the blood are called Hematologists. They use specialized equipment and techniques to identify and treat diseases related to the red and white blood cells and bone marrow.
Blood tests provide valuable information about the condition of blood cells, bone marrow and lymphatic system. A hematologist will order a complete blood count (CBC) to see the levels and characteristics of the red and white blood cells, hemoglobin and platelets. This is usually done by inserting a needle into a vein in the arm or obtaining a sample from a finger prick.
As per report published by Coherent Market Insights, the global Hematology Market size is valued at US$ 4537.5 million in 2019, and is expected to exhibit a CAGR of 7.80% over the forecast period (2019–2027).
Hematology doctors may focus on nonmalignant blood disorders, such as anemias and clotting problems, or malignant ones, including leukemia. They may specialize further in hematologic oncology, which focuses on the treatment of cancers that originate in the blood or bone marrow.
Blood-related diseases are a common cause of death and disability in the developed world. These diseases affect both children and adults and can be either benign or malignant.
A complete blood count (CBC) is a typical test conducted by Hematologists to detect and diagnose these conditions. This test analyzes the red and white blood cells, platelets, blood cell counts and blood proteins. It also tests the clotting ability of the blood and can detect some cancers and infections.
Along with performing a variety of routine hematology tests, hematologists may also work with other medical and surgical specialists, particularly oncologists, to care for patients with hematologic cancers. These cancers can be benign or malignant, and they may begin in any organ of the body.
Hematologists may also work in the field of transfusion medicine. They ensure adequate stocks of safe blood are available for blood transfusions and confirm the right type of donated blood is matched to a patient. They can also be involved in hematological research, where they work to improve the quality of life for people with diseases such as leukemia.
Medical hematologists can find jobs in hospitals, clinics and universities. They can also work in laboratories or in private practice. Some specialize in pediatric hematology, which deals with the growth and development of children’s blood cells. Others work in hospital or community hematology, where they provide care to people who have chronic and/or complex blood-related disorders.
In the field of Hematology, there is a growing interest in applying artificial intelligence (AI) and machine learning (ML). AI and ML are used to automate routine tasks such as cell typing or interpreting genetic variants. This allows hematologists to focus on more important clinical tasks and frees them up for research into new treatments. Nevertheless, hematologists must stay up to date with the latest developments in this area, as new ML-based models and prognostication systems are being released at a rapid pace. These new tools can help hematologists stay ahead of the curve and improve their patient outcomes.
