What Is Hemogram Test?

Are you curious to know what is hemogram test? You have come to the right place as I am going to tell you everything about hemogram test in a very simple explanation. Without further discussion let’s begin to know what is hemogram test?

Medical diagnostics play a vital role in assessing and monitoring an individual’s health. Among the various diagnostic tests available, the hemogram test, also known as a complete blood count (CBC), provides valuable insights into a person’s overall blood health. This commonly performed test helps healthcare professionals evaluate various components of the blood, aiding in the diagnosis and management of a wide range of conditions. In this blog, we will delve into the concept of the hemogram test, its components, significance, and its role in healthcare.

What Is Hemogram Test?

A hemogram test, or complete blood count (CBC), is a routine blood test that provides comprehensive information about the cellular components of the blood. It measures the quantity and quality of various blood cells, including red blood cells, white blood cells, and platelets. The test is performed using automated analyzers that rapidly analyze blood samples, generating a detailed report with specific parameters.

Components Of The Hemogram Test:

The hemogram test provides information on several key components of the blood:

  1. Red Blood Cells (RBCs):

The hemogram test measures the count and characteristics of red blood cells. This includes the hemoglobin level, which indicates the amount of oxygen-carrying protein in the blood, and the hematocrit, which represents the proportion of red blood cells in the total blood volume. Abnormalities in these parameters can indicate anemia, polycythemia, or other conditions affecting red blood cell production or function.

  1. White Blood Cells (WBCs):

The test evaluates the total count and differential count of white blood cells. The differential count categorizes different types of white blood cells, such as neutrophils, lymphocytes, monocytes, eosinophils, and basophils. Variations in the count and distribution of white blood cells can indicate infections, inflammatory conditions, immune disorders, or certain types of leukemia.

  1. Platelets:

The hemogram test measures the platelet count, which indicates the number of blood cell fragments responsible for blood clotting. Abnormal platelet counts can signify bleeding disorders, thrombocytopenia, or other conditions related to platelet dysfunction.

  1. Other Parameters:

The test may also include additional parameters, such as mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), and mean corpuscular hemoglobin concentration (MCHC). These parameters provide insights into the size and content of red blood cells, aiding in the classification of anemias and other blood disorders.

Significance And Role In Healthcare:

The hemogram test holds significant importance in healthcare for several reasons:

  1. Diagnostic Tool:

The test serves as an initial screening tool to assess a person’s overall blood health. It helps healthcare professionals detect and diagnose various conditions, including anemia, infections, inflammatory disorders, blood cancers, and bleeding disorders. Abnormalities in the test results may indicate the need for further investigation or specialized tests.

  1. Monitoring Disease Progression and Treatment:

The hemogram test plays a crucial role in monitoring disease progression and treatment effectiveness. Regular monitoring of blood cell counts and related parameters helps healthcare providers evaluate the response to therapy, adjust treatment plans, and track overall patient well-being.

  1. Health Screening:

The test is often included as part of routine health check-ups and preventive care. It helps identify early signs of blood disorders or underlying health conditions that may not present with obvious symptoms. Early detection can lead to timely intervention and better management of potential health concerns.

  1. Preoperative Assessment:

The hemogram test is commonly performed before surgical procedures to assess a patient’s overall blood health and identify any potential risks or complications. It helps healthcare providers make informed decisions regarding surgery and anesthesia management.


The hemogram test, or complete blood count (CBC), is a fundamental diagnostic tool that provides valuable insights into a person’s blood health. By evaluating various components of the blood, the test aids in the detection, diagnosis, and management of a wide range of conditions. Regular monitoring of blood cell counts and related parameters helps healthcare professionals track disease progression, assess treatment effectiveness, and ensure overall patient well-being. As a routine screening tool and an essential part of healthcare diagnostics, the hemogram test plays a critical role in promoting early detection, timely intervention, and optimal management of blood-related disorders.


What Does A Hemogram Test For?

This test is necessary in diagnosing anemia, hematological cancers, infections, acute hemorrhagic states, allergies, and immunodeficiencies. Also it is used for monitoring side effects of certain drugs. A pediatrician is frequently challenged for evaluating complete blood count as a part patient’s assessment.

What Is The Difference Between Cbc And Haemogram Test?

Hemogram and CBC test is used to measure a variety of blood disorders, among other conditions. However, a key difference between the two tests is that the hemogram test includes complete blood count tests (CBC) and ESR. A CBC test, on the other hand, does not include erythrocyte sedimentation rate (ESR).

What Does An Abnormal Hemogram Mean?

Abnormal levels of red blood cells, hemoglobin, or hematocrit may be a sign of anemia, heart disease, or too little iron in your body. Low white cell count may be a sign of an autoimmune disorder, bone marrow disorder, or cancer. High white cell count may be a sign of an infection or a reaction to medicine.

What If Hemogram Is High?

High hemoglobin count occurs when you have unusually high levels of a specific blood protein. The blood protein hemoglobin helps carry oxygen throughout your body and takes carbon dioxide to your lungs. High hemoglobin levels can lead to dizziness, fatigue, easy bruising and other symptoms.
