What is Hematology?

Hematology is the branch of medicine that studies the causes, diagnosis, treatment, and prevention of blood-related disorders. It entails treating disorders that impact blood production and its constituents, including blood cells, blood proteins, haemoglobin, bone marrow, blood arteries, platelets, spleen, and the coagulation process. Blood clots (thrombus), Hemophilia, various bleeding disorders, and blood malignancies like multiple myeloma, leukemia, and lymphoma are examples of these kinds of diseases. A medical laboratory scientist or a medical technologist or a medical technologist is often responsible for blood analysis in the laboratory.

Specialization

Hematologists or haematologists are doctors who specialize in haematology. Their primary responsibilities include caring for and treating patients with haematological disorders, while some might also work in a haematology laboratory, where they examine blood films and bone marrow slides below a microscope and interpret various haematological and blood coagulation test results. 


Hematopathology- The examination of diseases and abnormalities affecting and discovered in blood cells, their synthesis, and any organs and tissues engaged in hematopoiesis, including the spleen, bone marrow, and the thymus, is known as hematopathology or hematopathology. Hematopathology is frequently used in the diagnosis and treatment of diseases like leukaemia and lymphoma; techniques and technologies comprise flow cytometry investigations and immunohistochemistry.


Hematopathology seems to be a board-certified subspecialty in the United States, according to the American Board of Pathology. Pathology residents (clinical, anatomic, or combined) that have undergone hematopathology fellowship study following their pathology residency are generally board-eligible or board-certified hematopathologists.


Hematologists, hematology doctors, in certain institutions are also in charge of the haematology laboratory. Pathologists who specialize in the diagnosis of haematological illnesses, known as hematopathologists or hematopathologists, operate in haematology laboratories and most usually manage them. Hematologists and hematopathologists usually collaborate to make a diagnosis and, if necessary, give the best treatment. Hematology is a unique discipline of internal medicine that overlaps with medical oncology however is unique from it. Hematologists may specialize further or have specific interests, such as in the following areas:

  • Treatment of hematological malignancies that may include leukemia (cancers) and lymphoma.

  • The study of blood transfusion and the workings of the blood bank.

  • Treating hemoglobinopathies.

  • Treatment of bleeding disorders including idiopathic thrombocytopenic purpura and hemophilia.

  • bone marrow and Stem cell transplantation

Training

In the United States, beginning haematologists undergo a four-year medical degree accompanied by three or four years of residency or internship. They continue their education by spending two or three years studying how to diagnose, investigate, and treat blood diseases after graduation. When applying for this job, most employers look for the first-hand experience in a recognized training program that teaches the following skills: determining the reason for abnormalities in the creation of blood as well as other disorders, utilizing experimentation to diagnose a variety of blood-related situations or cancers, and providing the best possible diagnosis and services to patients.

Pediatric Hematology

Pediatric Hematology and hematology-oncology is a peer-reviewed worldwide medical journal dedicated to all aspects of pediatric haematology and oncology. Pathology, Immunology, and pharmacology in regard to blood illnesses and cancer in children are covered in this publication, which demonstrates how fundamental experimental research can aid in the understanding of clinical difficulties.


Annals of Hematology

The Annals of Hematology publishes articles on all aspects of clinical and experimental haematology, blood transfusion, hemostaseology, and related parts of medical oncology, such as lymphatic neoplasias, leukaemia, and solid malignancies, as well as hematopoietic stem cell transplantation. General topics of hematology-oncology, immunology, and molecular biology as they relate to human blood disorders are covered. The German Society for Hematology and Medical Oncology and the Austrian Society for Hematology and Oncology are both affiliated with the journal.


Clinical Hematology

Clinical haematology focuses on the diagnosis and treatment of blood and blood-forming tissue disorders.

In the field of haematology, diseases might include:

  • Blood cells (red blood cells (RBCs), white blood cells (WBCs) and platelets);

  • Other blood components;

  • The hematopoietic organs (bone marrow, spleen, lymph nodes).

Tests that Hematologists Perform:-

Complete Blood Count (CBC)- A complete blood count (CBC) measures your red and white blood cells, haemoglobin (a blood protein), platelets (tiny cells that stick together in order to form a blood clot), and hematocrit (the percentage of red and white blood cells in the blood).


Prothrombin Time (PT)- This test determines how long your blood takes to clot. Prothrombin is a protein produced by your liver that aids in the formation of clots. A PT test might assist monitor or diagnose your health if you're on a blood thinner or your doctor detects you have a liver disease.


Partial Thromboplastin Time (PTT)- The PTT, like a prothrombin test, determines how long it takes your blood to clot. If you're having problems with bleeding in any part of your body — nosebleeds, pink urine, heavy periods, or bruising excessively, your doctor can use a PTT to see if you have a blood condition.


International Normalized Ratio (INR)- If you take a blood thinner such as warfarin, your doctor might evaluate the findings of your blood clotting tests to those from other laboratories to ensure that the drug is functioning correctly and that your liver is in good shape. An international normalized ratio (INR) is the name for this calculation.


Bone Marrow Biopsy- A bone marrow biopsy might be required if your doctor believes you are not producing enough blood cells. A specialist would take a small sample of bone marrow (the soft stuff inside your bones) to be examined under a microscope by an expert.


Before the bone marrow biopsy, your doctor can apply a local anesthetic to numb the area. Because it is a brief operation, you will be awake while it.

FAQs (Frequently Asked Questions)

Q1. Name Some Disorders Related to Hematology.

Ans. Anemia, Malaria, Sickle cell disease, Hypercoagulability, Thrombocytopenia, Thalassemia, Bleeding disorders, Thrombosis, and Blood cancers are some disorders related to hematology. 

Q2. What is the Most Common Hematology Test?

Ans. The complete blood count, or CBC, is among the most used haematological tests. Anemia, clotting issues, blood malignancies, immune system abnormalities, and infections can all be detected with this test, which is usually done as part of a standard evaluation.
