An appropriate choice of statistical model can be difficult especially when measurements are made across a range of values of a physical characteristic, i.e. the reference value is a curve or a .

Quality Control Products A quality control product is a patient-like material ideally made from human serum, urine or spinal fluid.3 A control product can be a liquid or freeze-dried (lyophilized) material and is composed of one or more constituents (analytes) of known concentration.

Control products should be testedFile Size: 1MB. The data obtained in the interlaboratory study may indicate, however, that further effort is needed to improve the test method. Since the primary purpose of this practice is the development of the information needed for a precision statement, the experimental design in this practice may not be optimum for evaluating materials, apparatus, or.

In spite of routine criticism of linear and unidirectional models of scientific and technological innovation (for example, Bijker et al. ; Bijker and Law ), science studies scholars have devoted most of their attention to the movement of facts, techniques and individuals from the (basic) laboratory to industry.

Inter-laboratory studies/comparisons are performed with the aim of evaluating the extent of similarity in the results obtained by different laboratories using the same method.
