Complete Blood Count test is conducted to evaluate overall health status and detect certain underlying health conditions such as leukaemia, anaemia, infections, etc. The test determines if there is any significant increase or decrease in your blood count. The values vary depending upon your age and gender.
What happens during a CBC test?
The blood consists of three types of cells: Red Blood Cells, White Blood Cells, and platelets. The results of CBC will provide information about the number of cell types and other physical characteristics of some cells. Significant abnormalities in cells indicate the presence of one or more underlying conditions which becomes clear once the test results are out. Low platelet count may be the cause of excessive bleeding, etc.
When should I take the test?
The CBC test can be a part of your routine medical check-up. It helps you better understand your health. Apart from this, your doctor may recommend you to take this test when you have signs and symptoms which may relate to a condition that affects your blood cells. This test is also a part of the routine check to understand the progress of the given treatment for the respective condition.
How should I get ready for the test?
Usually, you don’t have to do much. A health practitioner will visit you to draw a small amount of blood from your vein. You can typically eat and drink normally before the CBC. However, your doctor may require you to fast for a specific amount of time before the test which is common if blood sampling is required for additional testing or so.
Is there anything else I should know about?
Sometimes the test results vary depending upon numerous factors. Blood cell populations differ due to many conditions such as intake of medication, smoking, etc. Recent blood transfusion also affect the CBC results.
The CBC values differ from babies to full-grown adults. The reports usually provide the reference range for different age groups which will be taken into consideration when a doctor interpret the results.
