The article describes the basic principles of control of quality, used in laboratory medicine with respect to forensic practice, and recommendations on interstate standardization.
The World Health Organization states that the main task of the laboratory – providing clinicians reliable qualitative and quantitative results of tests of samples of patients. Therefore, all laboratories should have a system of monitoring and maintaining the quality of their work. In this respect, the evidence of the results of forensic medical examination, including biochemical studies, can be achieved with the correct functioning of forensic laboratories. There is no doubt that the work of any laboratory, whether clinical, diagnostic, forensic or scientific research, provides for progressive realization of the quality control (QC) – intralaboratory and external.
Forensic Biochemistry Laboratory is specific and different from the other as a forensic laboratory units and the classical clinical diagnostic laboratories (Qld), as her research focuses on the assessment of the dead tissue with the terms of postmortem period and the results are quite different from the clinical laboratory. At the same time, the court can not be completely separated biochemistry from Qld, as forensic chemistry in many ways to the hosts, orders and regulations of the CED and standard laboratory methods, however, be adapted to the study of cadaveric material.
In the forensic laboratory of biological material is treated primarily with the positions of the objects of evidence. Bear in mind that in most cases there is no possibility of re-sampling of the material with subsequent studies (forensic and biochemical studies according to the order № 346n Ministry of Russia may be held for up to 10 days from the date of death). [5] Based on the above, it is obvious the value of asking questions of quality control laboratories in the court, especially in the judicial and biochemical laboratories.
Internal quality control is required for all research conducted in the laboratory [4]. Said KK assumes control of all procedures of laboratory research of biomaterials at all stages of its implementation: the availability and processing of specialized utensils, correct removal of biological material, storage and transportation to perform the analysis. In addition, the need for proper control of all stages of the forensic biochemical studies. Moreover, according to the order № 346n Ministry of Russia, taking a blood sample should be carried out within 24 hours after death. [5]
