Kokonaisverenäyte

Kokonaisverenäyte, meaning "complete blood count" in Finnish, is a common laboratory test that provides a broad overview of the cellular components of a person's blood. It is a fundamental diagnostic tool used to assess general health and detect a wide range of disorders, including anemia, infection, inflammation, and bleeding problems. The test measures several key parameters, including the number of red blood cells, white blood cells, and platelets.

Red blood cells are responsible for carrying oxygen throughout the body. A low red blood cell count can indicate anemia, while a high count might suggest polycythemia. White blood cells, also known as leukocytes, are crucial for the immune system's defense against infections. An elevated white blood cell count often signals an infection or inflammation, while a low count can impair the body's ability to fight off disease. Platelets are tiny cell fragments that play a vital role in blood clotting. Abnormal platelet counts can lead to excessive bleeding or the formation of dangerous blood clots.

In addition to counting these cells, a kokonaisverenäyte also typically analyzes their size, shape, and hemoglobin content. Hemoglobin is the protein in red blood cells that binds to oxygen. Variations in these characteristics can provide further clues about underlying medical conditions. The results of a kokonaisverenäyte are interpreted by a healthcare professional in the context of the patient's medical history, symptoms, and other diagnostic tests.
