Understanding the CBC Test: Definition, Requirement & Procedure



Today, blood tests are available at renowned diagnostic centres for detecting, analysing, and monitoring numerous diseases. There are full-body health check-ups that provide a comprehensive analysis of an individual’s bodily functions. One of the most common blood tests in a regular health check-up is a complete blood count or CBC test.

What is a CBC Test? 

A complete blood count (CBC) test is a diagnostic procedure that provides detailed information about the red blood cells (RBCs), white blood cells (WBCs), platelets, haemoglobin, and haematocrit. If any type of blood infection is present, a CBC test helps detect its severity. It can also detect other blood conditions like anaemia and leukaemia. It is best to look for an accredited diagnostic centre so that test results are genuine and accurate.

Why is a CBC Test Required? 

Most medical practitioners prescribe a complete blood count test to analyse the overall health of an individual. The levels of RBCs, WBCs, haemoglobin, etc., determine whether a person has an infection or disease in the blood. It is vital to investigate the components of the blood if there are symptoms of an infection. These include fatigue, inflammation, high fever, bleeding, and weakness. 

Additionally, the purpose of a complete blood count test extends to monitoring pre-existing blood-related diseases. These medical conditions affect one or more components of the blood. Their progression and severity can be tracked effectively to determine the right course of treatment.

What is the Procedure for a CBC Test?  

A CBC test requires a venepuncture in which a phlebotomist draws blood from one of the veins in the arm. The blood sample is then analyzed in a lab to measure various blood cell components. Trusted diagnostic centres typically provide your CBC test report within a few hours of sample collection. 

While a CBC test offers valuable insights, it might not always provide a complete diagnosis for blood-borne illnesses. It is crucial to only consult an experienced doctor to understand the test results. They might recommend further tests based on your specific condition. 

For individuals with concerns about exposure or exertion, an online health checkup can be a convenient alternative. Trusted pathology labs often allow you to book appointments and tests, including CBC, CRP, LFT, KFT, and more, directly through their websites or mobile apps. This service provides hassle-free at-home sample collection, making the process more comfortable and accessible.
