Hematologists are all about blood. They diagnose people with blood disorders and prescribe or administer appropriate treatments. There are many different types of blood disorders, including bleeding disorders and blood cancers. Hematologists also investigate ways to improve diagnosing and treatment of these disorders.Do You Have the Skills and Characteristics of a Hematologist?

Career Pathway Listen to this section
To practice as a hematologist, you must have eight years of education beyond high school, which includes medical school, medical residency, and a fellowship. In order to receive board certification—which is needed to practice hematology in the United States—the fellowship must occur in an approved hematology program. Hematologists must also be licensed in the state(s) they work in. Licensing requirements may vary from state to state.
Education- Typical Degree Needed After High School Listen to this section
high school credential
Typical degree for an entry-level position: Doctoral or professional degree ?
To become a board-certified hematologist, several requirements must be met:
- Four years of premedical education in a college or university.
- Four years of medical school resulting in an MD (Doctor of Medicine degree).
- Three years in a medical residency, typically in internal medicine or pediatrics, although other general residency programs may be used as well.
- Two- to five-year fellowship in a sub-specialty of hematology, specifically: adult hematology, pediatric hematology/oncology, hematology/oncology, coagulation, or pathology. During this time, the person may focus on either having a clinical or a research career.
Companies That Hire Hematologists

STEM Activities
STEM activities are fun hands-on explorations that usually take from 10 minutes to one hour and use readily available household or classroom materials while introducing you to STEM concepts common in this career.
Science Project Ideas
Project Ideas are in-depth STEM explorations that have a strong focus on controlling variables, taking accurate measurements, and analyzing data suitable for investigating the scientific method or the engineering design process.
On the Job
Role Models
Nature of the Work
A hematologist is a medical doctor who has been specially trained in the diagnosis and treatment of blood disorders. This includes a wide range of disorders, such as bleeding disorders (like hemophilia), blood cancers (like leukemia), blood clots (which can cause heart attacks and strokes if untreated), sickle cell disease, anemia, bone marrow disorders, rare blood disorders, and others. To diagnose a patient, the hematologist talks to the patient to understand the symptoms and other possible complicating factors. Since a hematologist is a specialist, patients are often referred to a hematologist by their primary doctor, so the hematologist often also has notes from the primary doctor to review and consider. The hematologist will also take and analyze blood samples (sometimes using several different tests) from the patient to make a diagnosis and to determine the most effective treatment plan.
Some of the treatments that a hematologist may administer, depending on the patient's blood disorder and condition, include:
- Various kinds of chemotherapy (for cancers)
- Radiotherapy (for cancers)
- Bone marrow or stem cell transplant (often for cancers)
- Blood transfusion (for anemia)
- Anticoagulation therapy (using anticoagulant drugs to prevent or treat unwanted clotting)
- Adding and/or removing different components from a patient's blood
- Immunosuppressive drugs
Some hematologists choose to be involved with research and/or primarily conduct research on different aspects of blood disorders. Both those who see patients and those who do research need to stay up to date on the latest research findings.
Work Environment
Hematologists may work in a small practice or in a larger group, such as in a hospital. If a hematologist works in their own small practice, they may also handle the business aspects of the practice, such as managing a staff of nurses and other administrative personnel. If the hematologist is part of a larger group, they may be actively involved in collaborations with others in the group, such as by participating in research initiatives, or serving on committees (committees are organized subgroups that regularly meet to make decisions about how to run different aspects of the large group itself). They may also work closely with other specialists—such as radiation oncologists—to treat patients, perhaps by developing a radiation therapy plan for a patient with cancer.
Hematologists may travel between several different locations, including a hospital or other medical facility (where they may perform surgeries and other medical procedures), a lab (where they analyze blood samples from patients), and a private office (where they do paperwork, read up on research, and write up their own research findings). They often encounter stressful situations where they need to remain calm and help keep patients calm.
