täisvererakkude

Täisvererakkude, or complete blood count (CBC), is a common laboratory test used to evaluate your overall health and detect a wide range of disorders, including anemia, infection, and leukemia. It measures several components and features of your blood.

The CBC typically includes counts of red blood cells, white blood cells, and platelets. Red blood cells are responsible for carrying oxygen throughout the body. Anemia is a condition characterized by a low red blood cell count. White blood cells are a crucial part of the immune system, fighting off infections. An abnormally high or low white blood cell count can indicate infection, inflammation, or other diseases. Platelets are small cell fragments that help in blood clotting, preventing excessive bleeding.

In addition to cell counts, a CBC often includes measurements of hemoglobin, the protein in red blood cells that carries oxygen, and hematocrit, the percentage of blood volume occupied by red blood cells. It can also provide information about the size and hemoglobin content of individual red blood cells, which helps in classifying different types of anemia.

The results of a CBC are interpreted by a healthcare professional in the context of a patient's medical history, symptoms, and other diagnostic tests. Deviations from normal ranges can signal the need for further investigation or treatment. This test is a fundamental tool in routine medical check-ups and in diagnosing and monitoring various medical conditions.
