Phlebotomy - a significant element of preanalytical stage of laboratory process
It is well-known that the results of laboratory testing directly influence to medical diagnosis and patient treatment. The quality of the results depends not only on modern laboratory equipment and well-trained laboratory staff. 70% of the errors in laboratory testing belong to preanalytical stage of laboratory process. Phlebotomy - blood evacuation - is one of the major concerns. Inappropriate patients identification, the wrong technique of blood collection, inadequate equipment can cause blood cells damage and change test results. So, the standartization of preanalytical phase, constant control over phlebotomy by laboratory staff and clinic administration, training and operative guidelines, certification of nurses increase the quality of laboratory testing and strongly influence effectiveness of hospitals.
