Have you ever had a blood test? Maybe your doctor looked at your blood report and said, "Let's show this to a blood specialist," and you might be wondering, "Who is that? What kind of person?" That's when we're going to meet a hematologist, a doctor who specializes in blood diseases. So today, let's talk about who a hematologist is, what they do, and when you might want to see one.
Simply put, who is this Hematologist?
A hematologist is a doctor who has specialized training in diseases related to your blood, bone marrow, and lymphatic system . Think of the blood in our bodies as roads that run across a country. A hematologist is someone who specializes in any problem that may arise, such as a problem with the vehicles (blood cells) that travel on these roads, or a blockage (blood clot) in the road.
These doctors spend several years studying the subject in depth after their general medical degree. That means they have at least 9 years of medical education and training. Some work in hospitals and clinics. Others work in labs. We call them ``Hematopathologists.'' What they do is examine your blood and tissues under a microscope and use various tests to accurately diagnose diseases.
In what cases are you referred to a Hematologist?
Usually, your family doctor (primary care doctor) will refer you to a specialist like this. There are various medical conditions or symptoms that can cause this. Let's take a look at what they are.
| Medical condition | A simple explanation |
|---|---|
| Anemia | This is a very common cause. Simply put, it is a decrease in the number of red blood cells in the blood. This can cause symptoms such as fatigue and paleness. |
| Blood clot in the veins (Deep Vein Thrombosis - DVT) | Blood clots form in the deep veins of the body, especially in the legs. This can be dangerous. |
| Types of blood cancer (Leukemia, Lymphoma, Multiple Myeloma) | Cancers that occur in the bone marrow, lymph nodes, or white blood cells. |
| Sepsis | An extreme, dangerous response by the body to an infection. This can even be life-threatening. |
| Hemophilia | This is a genetic disease. A condition where bleeding does not stop even from a small wound. |
| Sickle cell disease | It is a genetic disease in which the shape of red blood cells changes and they do not function properly. |
Remember, if you feel like you have these symptoms, don't panic and see your family doctor first. He or she will decide whether or not you need to be referred to a specialist.
What are the main tests and treatments a hematologist performs?
These doctors diagnose and treat diseases. These are some of the main things they do.
| Test / Treatment | Simply put, what happens? |
|---|---|
| Complete Blood Count (FBC) | This is a very common test. It checks the number and condition of all three types of cells in your blood: red blood cells, white blood cells, and platelets. |
| Blood clotting test (Prothrombin Time - PT) | It checks for bleeding or clotting disorders, and it can also check if the medications you are taking are working properly. |
| Blood Transfusion | Transfusion of healthy blood to replace blood lost from your body due to surgery, accident, or illness. |
| Chemotherapy | A treatment given to cancer patients. Chemicals are given to the body to destroy rapidly growing cancer cells. This is done by a Hematologist-Oncologist. |
| Bone Marrow Transplant | This is also called a stem cell transplant. The diseased bone marrow is replaced with healthy stem cells (either your own or from a donor). |
| Ablation Therapy | A treatment method that destroys damaged tissue using heat, extreme cold, laser rays, or chemicals. |
What happens when you go to see the doctor?
You may not always see a hematologist face-to-face. They often work in conjunction with your family doctor, pediatrician, or oncologist. They analyze your blood test results, monitor your condition, and provide the necessary advice.
- The person who takes your blood sample is usually a lab technician.
- The blood draw only takes a few minutes, but the test results can take several days to come back.
- If you have a long-term blood disorder like hemophilia, you will need to see a hematologist regularly.
