Background

The analysis and detection of the concentration of a tangible component and a content in a sample such as blood or body fluid of a human or an animal is a medically very important and routine examination item. The detection of the visible components in the blood includes the detection of parameters such as the number, size and shape of red blood cells, white blood cells and platelets in the blood.
