Accreditation systems are usually designed to address all of these components. Quality control in Biochemistry laboratory Quality Assurance in the biochemistry laboratory is intended to ensure the reliability of the laboratory tests. Accuracy can, as a rule, be checked only by the use of reference materials which have been assayed by reference methods. (1981) A multi-rule shewhart chart for quality control in Clinical Chemistry. The Joint Commission has underlined this fact by stating that the laboratory is required to “systematically assess and improve important functions and work processes and their outcomes.”1It is therefore imperative to lay down certain benchmarks to assess laboratory functions. @��i8���WD�Xa#�똜��~�F(�oHPAIV�wrM����{!���_�E���8)�@���vW6Ҥ)�Ná���v�2������5��{����^�FΈnA O�C+����g�?��Y�q�|��0&/�@V`����\> p�4�y��0Z�(��W��������d���^u27N�s�jsX�+e1�ݝTޅ՞���l�,��`K^��T|�:& �9/��fQcb �h�Pn�%2)��_� e��D3����L�VU?4S�GGy��W�-��c���$����”���b{I�W�+y\�i�ώ��D��b�d Ƶ�O�+}h�/�D�#'�]���j`±�՚2m��3��[6�����(k�����F{]���̰c\����O��B�����, Z�@tk�?>�c������e���W������ �9�V�V����2&p��B a2�u�>��wLʃ[�3zo(�k � P/�qS���q�1S{���zi���t]hz�4#�/:�o��H�. 6.
