punasolumäärän

Punasolumäärä refers to the count of red blood cells in a given volume of blood. Red blood cells, also known as erythrocytes, are a critical component of blood, responsible for transporting oxygen from the lungs to the body's tissues and carrying carbon dioxide back to the lungs. Measuring the red blood cell count is a standard part of a complete blood count (CBC) test.

A normal red blood cell count varies slightly between individuals and depends on factors such as age, sex, and altitude. Generally, a low red blood cell count, known as anemia, can indicate various medical conditions. Symptoms of anemia may include fatigue, weakness, pale skin, and shortness of breath. Conversely, an elevated red blood cell count, a condition called polycythemia, can also signal underlying health issues, such as dehydration or certain bone marrow disorders.

The measurement is typically expressed as the number of red blood cells per microliter (µL) or per liter (L) of blood. Factors like hydration levels can temporarily affect the concentration, and persistent deviations from the normal range often warrant further medical investigation to determine the cause and appropriate treatment. Medical professionals use this parameter in conjunction with other blood test results to diagnose and monitor a wide range of health conditions.
