Have you ever wondered why doctors often request a complete blood test during a health check? The answer is simple: because blood stores a lot of important information about your body’s condition.

A complete blood test, or complete hematology, is a basic test that provides a general overview of a person's health. Through just one blood sample, many things can be detected—ranging from signs of infection, anemia, to potential immune system disorders.

This test examines three main components of blood:

Red blood cells, which carry oxygen throughout the body. If the count is low, it could indicate anemia.

White blood cells, which act as the body's "soldiers" against infection.

Platelets, which help blood to clot when the body is injured.

The test results can also show the size and shape of blood cells, as well as how dense essential substances are within them. This helps doctors determine whether PRAMITA friends are lacking certain nutrients, dehydrated, or experiencing an active infection.

Besides diagnosis, this test is also useful for:

Checking overall health condition

Finding the cause of symptoms like fatigue, fever, or easy bruising

Monitoring disease progress

Evaluating the effectiveness of ongoing treatment

The procedure is simple. A blood sample is taken from a vein in the arm, then analyzed in the lab. The results are usually compared to normal reference ranges, and doctors will explain if there’s anything that needs further attention.

However, keep in mind that complete blood test results are not the sole basis for a diagnosis. Doctors will still consider symptoms, medical history, and may recommend additional tests if needed.

So don’t hesitate to do routine blood tests, especially when feeling unwell or to ensure the body stays in its best condition. Prevention is better than cure, right?
