Hematology Tests

Hematology is a medical branch that studies blood, blood-forming organs, and blood-related diseases. This field primarily involves diagnosing and treating hematological conditions, including anemia, leukemia, lymphomas, and blood clotting disorders. Hematology tests are vital in assessing a patient’s overall health status. These analyses encompass various tests, including complete blood counts, as well as detailed assessments of blood cells, hemoglobin, platelets, and other vital blood components. At IntroLab in Belgrade, we offer a full suite of hematological analysis services. Our services are crucial in early identification and continuous monitoring of hematological conditions, ensuring precise diagnosis and effective treatment strategies.

What are hematological analyses?

Hematological analyses comprise several laboratory tests that evaluate blood composition and functionality. These tests provide comprehensive insights into the count and variety of blood cells, including erythrocytes (red blood cells), leukocytes (white blood cells), platelets, hemoglobin levels, coagulation factors, and other crucial blood parameters. Such diagnostic techniques are broadly utilized for purposes ranging from assessing general health to diagnosing and monitoring specific hematological conditions.

Who conducts these tests?

Hematological analyses are performed in laboratories by specialized medical experts known as hematologists. These professionals are equipped with the necessary expertise to interpret the results of these tests and provide relevant information to patients and other physicians. Utilizing state-of-the-art laboratory equipment, hematologists ensure the precision and reliability of these results.

When are hematology tests typically required?

Hematological analyses are typically needed in various scenarios. These tests are commonly conducted during routine health check-ups or as part of preventive health screenings to assess the overall condition of the blood. Additionally, when symptoms suggest a potential blood disorder or disease, physicians may order these tests for accurate diagnosis and to monitor the progress of the patient’s condition.

Purposes for performing hematological analyses

The objectives of conducting these tests are multifaceted. These tests are key in the detection and ongoing management of various blood disorders, including anemia, leukemia, hemophilia, and thrombocytopenia, among others. Additionally, they are valuable for evaluating the effectiveness of treatments and determining the necessity for blood transfusions. These analyses are also beneficial in detecting infections, inflammations, and other medical conditions that may impact blood health.

Signs of blood disorders

A range of symptoms and indicators often manifest in blood disorders, suggesting irregularities in blood functionality. Awareness of these symptoms is crucial for patients to identify potential issues and seek medical care. Here are some common signs associated with blood disorders.


Anemia is a condition marked by a reduced number of red blood cells or a lower hemoglobin concentration in the blood. The key symptoms include fatigue, weakness, skin and mucous membrane pallor, dizziness, shortness of breath, rapid heart rate, and headaches. These symptoms arise from insufficient oxygen delivery to the body’s tissues and organs.

Hemostasis disorders

Disorders of hemostasis impair the blood’s clotting ability, which is crucial for stopping bleeding. Common symptoms include frequent, prolonged bleeding after injuries or surgeries, easy bruising, and gum bleeding. Additionally, individuals with these disorders may be more susceptible to forming hematomas or blood clots.


Thrombophilia is a tendency towards excessive formation of blood clots. Those with thrombophilia face an elevated risk of deep vein thrombosis, pulmonary embolism, or stroke. The symptoms can vary, including swelling, pain, redness, warmth in the limbs, shortness of breath, chest pain, or neurological symptoms in the case of brain clots.

Enlarged lymph nodes

Enlarged lymph nodes, or lymphadenopathy, may indicate various blood disorders like lymphomas, leukemias, and infections. Patients may notice swollen, tender lymph nodes in areas like the neck, groin, armpits, or elsewhere. Other signs might include weight loss, night sweats, fatigue, or a heightened infection propensity.

Symptoms of blood disorders vary based on the specific disorder and individual patient characteristics. Should you experience any of these symptoms or have blood health concerns, seeking medical advice for diagnosis and treatment is crucial. Prompt identification and management of blood disorders are key to maintaining health and avoiding complications.

Hematological blood analysis services at IntroLab

IntroLab offers a comprehensive suite of hematology tests, crucial for an in-depth evaluation of a patient’s health. These tests are specifically designed to analyze different blood parameters, providing detailed insights into individual health conditions.

  • Eosinophils in sputum: This test involves analyzing eosinophils in sputum, primarily for patients with respiratory conditions like asthma, to detect lung inflammation.
  • Nasal smear for eosinophils: This test examines eosinophils in nasal secretions, helping diagnose conditions such as allergic rhinitis and nasal inflammation.
  • Complete blood count with differential: This test provides a detailed analysis of different types of blood cells, helping diagnose various blood-related conditions.
  • Reticulocytes: This test measures the proportion of reticulocytes (immature red blood cells) in the blood, providing valuable information about red blood cell production in the bone marrow. It’s an important indicator of bone marrow function and response to anemia.
  • Erythrocyte sedimentation rate: This test measures the speed at which red blood cells settle in a tube, with an increased rate possibly indicating inflammation or infection.
  • Lymphocyte subpopulations: Identifying and evaluating various types of lymphocytes, such as T cells, B cells, and natural killer cells, aids in diagnosing autoimmune diseases and immunodeficiencies.
  • T Lymphocytes (CD4+): The count of CD4+ T lymphocytes, crucial for the immune system, is assessed, especially for HIV/AIDS patients.
  • Platelets: Platelet count and function are analyzed, which are key in diagnosing coagulation disorders and assessing risks of bleeding or thrombosis.

These tests provide comprehensive insights into the different aspects of hematological health, facilitating accurate diagnoses and the development of personalized treatment plans.

Preparation for hematology tests

Preparing for hematological tests is straightforward, with adjustments made according to the specific requirements of each test. Generally, no special preparations are needed for most tests. However, some patients may need to fast for 8 to 12 hours before blood is drawn. It is essential for patients to notify the medical staff about any current medications, vitamins, dietary supplements, or ongoing treatments, as these can influence the outcomes of the test results.

Blood samples are typically collected through venipuncture, where blood is drawn from a vein in the arm. While possibly daunting for some, this procedure is quick and causes only minor discomfort. Hematology tests are vital for diagnosing blood-related diseases and monitoring overall health. Hence, conducting these tests in reputable laboratories like IntroLab, equipped with the latest technology and offering quality services for both health and preventative check-ups, is important.
