Punasolumäärä

Punasolumäärä, also known as red blood cell count or erythrocyte count, refers to the number of red blood cells in a given volume of blood. It is a fundamental component of a complete blood count (CBC) and provides crucial information about a person's health. Red blood cells, or erythrocytes, are responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs for exhalation.

A normal punasolumäärä varies slightly between men and women, with men typically having a higher count. Factors such as age, altitude, and physiological state can also influence these values. A low punasolumäärä, known as anemia, can indicate various underlying conditions such as iron deficiency, vitamin B12 deficiency, chronic diseases, or excessive blood loss. Symptoms of anemia can include fatigue, weakness, pale skin, and shortness of breath.

Conversely, an abnormally high punasolumäärä, termed polycythemia, can be caused by dehydration, lung disease, certain cancers, or genetic factors. Polycythemia can lead to an increased risk of blood clots, stroke, and heart attack due to the thicker consistency of the blood.

The measurement of punasolumäärä is typically performed using an automated hematology analyzer, which counts the cells in a blood sample. This simple yet vital test is a cornerstone of medical diagnostics, aiding physicians in identifying, monitoring, and managing a wide range of health issues. Regular monitoring of punasolumäärä can be part of routine health check-ups or specifically ordered to investigate suspected conditions.
