The causes lies perhaps in some serum factor, which could disturb some modifications of the radioimmunoassay more than others. There was no improvement of precision when the same insulin Standard was used in all laboratories. Standard curves made up in different human fasting sera have a scatter only within the ränge of pipetting and counting error.

Quality control of routine methods largely is performed by means of participation in group experiments. The aim of this work was to design and to test a modell for collaborative, comparative studies on the radioimmunological insulin determination with the goal of improving the inter-laboratory precision. in his own buffer system, and using his usual concentrations. The unknowns were then evaluated with the laboratory's own Standard curve, as well as with the Standard curve containing the common insulin Standard. Second g r o u p e x p e r i m e n t ( 1 9 7 3 ) : The samples assayed in the second group experiment were as follows: Nine samples from a new serum pooL Triplicates of seven serum samples drawn from a further patient during an OGTT. Times of venipuneture: 0, 5, 1 0 , 15, 20, 3 0 and 6 0 minutes after administration of glucose. Triplicates of 8 samples to form the recovery curve. These were made in human serum with a low basal concentration of insulin. For this we used the serum of a fasting patient which contained approximately 6 M U insulin/ml. 2 0 0 /utU insulin were then dissolved in each millilitre of an aliquot of this serum, so providing a stock serum Standard of 206 M U insulin/ml. From this, further serial 1 + 1 dilutions were made, using the rest of the low insulin serum as diluent. Thus the following Standards were obtained 206, 106, 5 6 , 3 1 , 18.5, 12.3, 9.2, and 6 /uU/ml. In all cases the identity of the samples was withheld from the partieipants. Results First group experiment The individual group modifications of the insulin RIA technique are shown in Table 1. Because all unknowns were measured in one assay-run, the within assay coefficient of Variation could be obtained from the 24 samples of the serum pool. This ranged between 3.4% and 14%. The scatter of the means of the 24 values from each laboratory was between 21 Material and Methods juU/ml and 46 /iU insulin/ml and had a coefficient All experiments were performed on the same samples by of Variation .of 21%.

Marschner et al. Fig. l a Results of the insulin-determinations of the serum pool (n=9) as calculated from each laboratory's own Standard curve in buffer (second group experiment). The results from each laboratory are represented in a Gaussian-curve. As usual the peak of each curve represents the mean value, the width of each curve between upper and middle third is two Standard deviations. The peaks (means) have a scatter with a coefficient of Variation of 28%. The results of the first group experiment (cf. text) were similar. Fig. l b The same data, related to the recovery curve, i.e. Standards dissolved in low insulin serum. Coefficient of Variation of the means 8%. to the first one. In this way we were able to evaluate all hormone concentrations using one method, and so record only the differences of the assay variations. This was done with a Computer program, using spline approximation to fit the Standard curve. A Siemens 404/3 data processing machine was employed. The curves were plotted by an on-line controlled Hagenplotter (Marschner, E r h a r d t and Scriba 1973). The count rates of the unknowns from the various groups were related firstly to their corresponding Standard curve and then to their recovery curve. Calculation o f the unknowns, using the S t a n d a r d curve i n buffer The means of the 9 serum pool samples from all seven groups had a scatter with a coefficient of Variation of 28%. This, and also the individual within assay precision were not appreciably different from the results of the first experiment (Fig. la). Similar results were also obtained by comparing the hormone values from the OGTT in both group experiments (Fig. 2a). C a l c u l a t i o n of the unknowns, using the recovery curve By calculating the insulin concentrations of the samples from the serum pool (Fig. lb) and those from the OGTT (Fig. 2b) using the recovery curve (see above) we obtained a great improvement of interlaboratory precision. Inspite of the fact, that the individual within-assay precision remained nearly uninfluenced, the scatter of the means of the pooled serum was reduced to a coefficient of Variation of only 8% from 28%. It was noticed, that the recovery curves in serum generally had a gradient steeper than the Standard curves in buffer (Fig. 3).

We examined the usefulness of various human fasting sera for insulin recovery curves and prepared 7 recovery curves as described above. Triplicates of 4 comtrol samples calculated by the Computer on each of the 7 recovery curves, showed a coefficient of Variation not greater than 7%, which lays within the precision of the assay. 8[%| RECOVE RY C: U R V E \ Discussion S T A N D A R D CU RVE Group experiments are a well aeeepted procedure to examine the validity of laboratory results. For ordinary laboratory methods one or two determinations of a substance are sufficient for such a project whereas because of the nonlinear RIA Standard curves 6 to 8 determinations in triplicates of samples having concentrations which are spread over the sensitive part of the Standard curve are essential. \^\^ \\ It is desirable, that the concentrations of the samples are within a physiological context, like in our case from an OGTT. To make sure, that the results represent all individual laboratory errors, each partieipant should handle his samples as in a routine assay. A detailed Information about the individual assay is not necessary. The only important fact is the agreement of results with those of other laboratories. Since one is commonly interested in comparing assay Systems and not the different evaluation procedures, it is advantageous to ask for count rates instead of hormone concentrations.

It is apparent, that the precision will decrease a little, if each laboratory uses a different serum for its own Standards. Despite this, our results suggest, that this decrease would not be great. It is, furthermore recommended that Standards be made by serial dilutions of 1 + 1, starting from one stock Solution containing about 200 to 300 juU/ml. Thereby, it is necessary to The two group experiments, regarded as pilot studies, use only one pipette and one Single volume, resulting show, that both the type of the RIA System (antiin a precision superior tc all other ways of pipetting body, bound-free-separation, incubation-time and Standard dilutions. -temperature, sample volume) are of secondary importance in improving inter-laboratory precision.

From the count rates of the Standard curves one gets also Information about the steepness of the slope of the Standard curves and the limits of sensitivity (threefold Standard deviation of the zero-standard). A coefficient of Variation greater than 20% is considered too high for satisfactory hormone measurement, particularly when needed frequently, for clinical and research purposes and when the RIA itself is relatively simple (Ashford et al. 1969). This can be improved considerably, however, by using Standards in serum. In this way the inter-laboratory precision approximates to the ränge of such assays as cholesterol or urea-nitrogen (Stamm and Büttner 1969). cedures in clinical medicine and research.
