What Is Hematology?

Hematology is the branch of medicine concerned with the study and management of blood, bone marrow, and blood-related disorders. Blood has several main components, each with a different job:

• Red blood cells carry oxygen from the lungs to the rest of the body.
• White blood cells are part of the body’s defence against infection.
• Platelets help blood clot and stop bleeding.
• Plasma is the liquid part of blood that carries cells, nutrients, and proteins.

When any of these is too low, too high, or not working properly, a range of symptoms and conditions can follow.

When Should You Consult a Hematologist?

A physician may recommend a hematology consultation for:

• Persistent or unexplained anemia
• Abnormal blood test results
• Unexplained low platelet counts
• Recurrent bleeding
• Suspected blood clotting disorders
• Unusual changes in white blood cell counts
• Suspected blood or bone marrow disorders

These findings do not automatically mean a person has a serious blood disease. Clinical evaluation is required.

Blood Disorders Evaluated by Hematology Specialists

The list below is general information about the field of hematology. The conditions Dr. Nur Mohammad personally treats should be confirmed before this is presented as a list of his services.

Anemia

Anemia occurs when the body does not have enough healthy red blood cells or hemoglobin to carry oxygen effectively. Possible causes include iron deficiency, vitamin B12 or folate deficiency, chronic diseases, blood loss, and certain inherited conditions. Many cases of anemia can be assessed by a general physician. Persistent, unexplained, or severe anemia is where a hematology consultation becomes more relevant.

Thalassemia

Thalassemia is an inherited blood disorder that affects hemoglobin production. It runs in families, and screening and genetic counselling can matter for families with a history of the condition.

Platelet Disorders

Platelets help the body form blood clots. A platelet count that is too low or too high can affect bleeding or clotting, and the right next step depends on the cause.

Blood Clotting Disorders

Some conditions cause excessive bleeding, while others cause abnormal clot formation. Both need proper evaluation, because the symptoms and risks are different.

White Blood Cell Disorders

Abnormal white blood cell counts may be associated with infections, medication effects, or blood-related diseases. A single abnormal result often needs to be repeated or interpreted alongside other findings.

Blood Cancers

Leukemia, lymphoma, and multiple myeloma are cancers involving blood-forming tissues or related cells. Hematology includes their evaluation, but treatment pathways depend on the diagnosis and on the clinical services available. Do not imply that every hematology specialist provides cancer treatment or chemotherapy. Confirm Dr. Nur Mohammad’s specific services before listing any.

Common Symptoms of Blood Disorders

Certain symptoms may warrant medical evaluation:

• Persistent fatigue or weakness
• Pale skin
• Frequent or unexplained bruising
• Recurrent nosebleeds
• Bleeding gums
• Unusually heavy bleeding
• Repeated infections
• Unexplained fever
• Swollen lymph nodes
• Unexplained changes in blood test results

When Should You Seek Medical Attention?

These symptoms can have many causes, and a checklist cannot tell you which one applies to you. A proper assessment is needed rather than self-diagnosis. Seek urgent medical attention for severe bleeding, difficulty breathing, fainting, or other serious symptoms

Common Tests Used to Evaluate Blood Disorders

A clinician may order different tests depending on your symptoms:

• Complete Blood Count (CBC)
• Hemoglobin test
• Peripheral blood smear
• Platelet count
• Iron studies
• Vitamin B12 and folate tests
• Coagulation tests
• Other specialized tests when indicated

Test selection depends on the medical history, the examination, and the initial results. Not every patient needs every test.

Why Is a CBC Important?

A CBC measures several components of the blood, including red cells, white cells, and platelets, and can help identify abnormalities that need further evaluation. An abnormal result does not establish a diagnosis on its own. It is a starting point for deciding what to look at next
