CBC vs Hemogram Test: Evaluating Blood Health

Blood tests are often the first step towards understanding what’s happening inside the body. And when it comes to analysing blood work, among the most commonly recommended tests are the Complete Blood Count (CBC) and hemogram test. While both are sometimes used interchangeably and provide valuable information, some factors differentiate the two. 

What is CBC?

CBC, or a Complete Blood Count test, provides a broad overview of key blood components that help identify underlying health conditions. A CBC measures: 

  • Red Blood Cells (RBCs): Responsible for carrying oxygen throughout the body
  • White Blood Cells (WBCs): The body’s defence system against infections
  • Platelets: Help wounds heal through blood clotting
  • Haemoglobin: The oxygen-carrying protein present in red blood cells
  • Hematocrit: Indicates the proportion of red blood cells in the blood

The CBC test price is generally affordable, making it a widely accessible option that is routinely included in health check-ups. Doctors usually recommend a CBC test to identify the cause of symptoms such as persistent fatigue, fever or weakness. 

What is a Hemogram Test?

A hemogram test is built on the foundation of CBC but offers a more comprehensive evaluation of blood health. In addition to the parameters included in a CBC test, the hemogram test includes advanced indicators, including:

  • Differential WBC Count: A breakdown of different white blood cells, including neutrophils, lymphocytes, monocytes, eosinophils, and basophils, offering insight into immune responses against infections.
  • Red Cell Indices (MCV, MCH, MCHC): These parameters evaluate the size and haemoglobin content of red blood cells. This parameter is crucial for diagnosing different types of anaemia.
  • Reticulocyte Count: These are immature red blood cells. The parameters help measure how efficiently the bone marrow is producing new red blood cells.

A complete hemogram test uses specific testing methods for enhanced analysis.

  • Peripheral Smear: This involves microscopic examination of blood cells to detect their shape, size and overall structure. This test is particularly useful to detect abnormalities that may not have been evident before.
  • ESR (Erythrocyte Sedimentation Rate): A method that measures the rate at which red blood cells settle at the bottom of a test tube over an hour. It helps identify inflammation within the body.
Both CBC and hemogram tests help provide a clear picture of the blood health, supporting diagnosis and treatment response

A Brief Introduction to CBC Test: Meaning, Purpose, and Procedure

Image
A complete blood count (CBC) test is a common blood test to measure and analyse an individual's health. A CBC test is part of a full-body health check-up by trusted medical laboratories. It provides proper information about various blood components, including red blood cells, white blood cells, platelets, haemoglobin, and haematocrit. The doctor prescribes this test for several reasons, such as the detection of conditions, disorders, and infections. Top medical laboratories conduct CBC blood tests at an affordable cost . Why is a CBC Test Required? The CBC test is required to check an individual's overall health and well-being. If one has symptoms like fever, fatigue, bleeding, or weakness, the doctor may order a CBC test. It tells the doctor about the level of red blood cells, white blood cells, platelets, and other blood components. The medical professional analyses the blood components to check for infections or diseases. Along with this, CBC test results can also help d...

A Comprehensive Look at the Double Marker Test During Pregnancy

Image
Double marker test is a prenatal test recommended for women during pregnancy. The test checks for any genetic disorder or risk for certain birth defects in the unborn child.  A double marker test in pregnancy , is conducted during the first trimester and analyses two specific substances for chromosomal abnormalities.  Women over the age of 35 and having a history of birth defects should consider getting a dual marker test. Levels of substances can help identify the risk of certain birth defects, like Down syndrome. Types of Pregnancy Hormones Measured A double marker test includes a blood sample and an ultrasound. The blood sample is taken to look for two hormones—the free beta human chorionic gonadotropin (beta-hCG) and pregnancy-associated plasma protein A (PAPP-A). An ultrasound called a nuchal translucency (NT) scan, examining the clear tissue at the back of the baby’s neck.  Timing of Tests  There is a relatively slim window for conducting the dual marker test. ...

What You Should Know About the Thyroid Antibodies Test

Image
A thyroid antibody test is a blood test that measures the amount of thyroid antibodies present in the blood. While normally, the production of antibodies is the body’s way of fighting infection, bacteria, viruses, and other foreign substances, in rare cases, the immune system ends up producing antibodies that attack healthy parts of the body, a condition known as autoimmune disease. When these antibodies attack healthy thyroid cells, they can damage thyroid tissues, impacting the normal functioning of the thyroid gland.  Different Types of Thyroid Antibodies Thyroid peroxidase antibodies (TPOAb): These antibodies can indicate an underactive thyroid (hypothyroidism) caused due to a condition known as Hashimoto’s disease. Thyroglobulin antibodies (TgAb): These antibodies can be a sign of Hashimoto’s disease. Thyrotropin receptor antibodies (TRAb): These antibodies bind to the TSH receptor on thyroid cells, stimulating the gland to produce excess thyroid hormones. They are the primar...
