Blood Cell Counter Conductometric

Introduction

A conductivity blood cell counter is a device that is used to measure the number of red blood cells in the blood. It is based on the principle of measuring the electrical resistance of blood conductivity. This method is more sensitive and accurate than the optical method, which uses dyes and a microscope. Conductometry can also more accurately determine blood cell counts in patients with leukemia or anemia where traditional testing methods often fail.

Description of the operation of the blood cell counter

The conductometric reaction is the reaction of the conductivity of ionic solutions caused by an increase and decrease in the concentration of ions. The operating principle of the meter is based on measuring the electrical conductivity of a solution, which changes when electrical charges are formed in the solution (charging of ions).

Blood cell counters use electrodes to measure the electrical conductivity of the blood. Blood is a complex mixture of electrolytes, so the results of conductivity changes are caused not only by red blood cells, but also by other blood components such as plasma, proteins and salts. Therefore, conductivity measurements do not always give the same results in different patients.

The requirements for the selection of electrodes for a blood cell counter are very high. They must be made of special materials that have high thermal conductivity in order to minimize heat loss during operation of the device. In addition, the electrodes must have precise geometric shapes and dimensions to ensure uniform current distribution between them.

Advantages of using a conductivity blood cell counter:

High measurement accuracy - compared to other methods, conductometric meters have higher accuracy. This is especially important for monitoring the condition of patients with severe diseases such as leukemia and anemia. Wider diagnostic range - conductometric measurement can help detect some diseases that are currently difficult to diagnose with other methods. For example, some types of blood cancer can affect the electrical conductivity of the blood, allowing them to be detected at an early stage.
