Haemogram Test: Purpose, Procedure, and What Your Results Mean

What is a Haemogram Test?

A haemogram test is a common blood test. It is also called a complete blood count. Doctors use it to check your overall health. The test measures different parts of your blood. For example, it looks at red blood cells, white blood cells, and platelets. Because it gives a lot of useful information, it is often one of the first tests ordered during a health checkup.

Why is a Haemogram Test Done?

Doctors may suggest a haemogram test for many reasons. Sometimes, you may feel tired or weak. Other times, you may have a fever or infection. In these cases, a haemogram test can help find the cause. Additionally, it can help monitor ongoing health problems. For example, people with anemia or infections often need regular haemogram tests. In short, this test helps doctors spot health issues early.

How is the Haemogram Test Performed?

The haemogram test is simple and quick. First, a healthcare worker cleans your arm. Next, they use a small needle to take a blood sample from a vein. Usually, the process takes only a few minutes. Afterward, your blood goes to a lab for testing. Most people feel only a small pinch. However, some may have mild bruising or soreness.

Understanding Your Haemogram Report

Once your test is done, you will get a haemogram report. This report lists your blood parameters. It shows the number of red blood cells, white blood cells, and platelets. It also includes other details, such as hemoglobin and hematocrit levels. Each value is compared to normal haemogram values. If a value is too high or too low, your doctor will explain what it means. For example, low red blood cells may suggest anemia. High white blood cells could mean an infection.

Normal Values and What They Mean

Normal haemogram values can vary by age and gender. However, most labs use similar ranges. Here are some common blood parameters and their usual ranges:

  • Red Blood Cells (RBC): 4.5–5.9 million cells/mcL (men), 4.1–5.1 million cells/mcL (women)
  • White Blood Cells (WBC): 4,000–11,000 cells/mcL
  • Hemoglobin: 13.5–17.5 g/dL (men), 12.0–15.5 g/dL (women)
  • Platelets: 150,000–450,000 cells/mcL
  • Remember, normal ranges may differ slightly between labs. If your values are outside the normal range, it does not always mean you are sick. Sometimes, small changes are normal. However, your doctor will help with haemogram interpretation.

    When to Consult a Doctor

    It is important to talk to a doctor if your haemogram report shows abnormal results. Even if you feel fine, some changes may need more tests. For example, low hemoglobin can cause tiredness. High white blood cells may point to an infection. Therefore, always discuss your results with a healthcare professional. They can guide you on the next steps.
