Demonstration of total blood count by cell analyzer
There are three types of cells in the bloodstream namely leucocytes (white blood cells), erythrocytes (red blood cells), and thrombocytes (platelets). The complete blood count is the most common blood investigation advised by the doctor to know the overall health of the subject.
The hematology analyzers are used to detect the total count of blood cells and also to diagnose diseases of the blood cells and monitor the health condition of the patient. Some of the complex analyzers also measure the cell morphology and help in the diagnosis of rare blood disorders. The technologies used in hematology analyzers are electrical impedance, flow cytometry, and fluorescent flow cytometry.
The aim of the experiment is to demonstrate total blood count by a cell analyzer.
REQUIREMENTS
Subjects: Human
Apparatus: Hematology analyzer
Blood sample
PROCEDURE
The subject is either in a sitting or lying down position. The suitable vein is punctured by placing a tourniquet 3- 4 inches above the puncture site. The blood is collected and sent for analysis.
The following technologies are used in hematology analyzers.
Electrical impedance
This is known as the Coulter principle, used in most analyzers. The blood is passed between two electrodes through a narrow aperture which can pass a single cell at a time. The change in impedance is proportional to the cell volume, which in turn measures the cell count and volume.2
Flow cytometry
It is used to determine 5-part WBC differentials. The single stream of light passing through the laser beam measures cell granularity, diameter, and inner complexity. The addition of fluorescent reagents to flow cytometry renders it fluorescent flow cytometry which measures specific cell populations namely platelets, nucleated RBCs, and reticulocytes.2
CONCLUSION
Complete blood count analysis is used in diagnosing diseases, monitoring health conditions, and knowing the prognosis of medical treatments.
