If the instrument is not able to perform agglutination measurements, measure the
microplate five times.
Then rotate the microplate by 180 ° and then measure the microplate five times.
For a number of wells, calculate the average optical density value from all the
measurements for these wells.
Compare the average value against the highest and lowest measured values.
Example
Measured Values
0.945, 0.956, 0.937, 0.926, 0.971, 0.936, 0.961, 0.939, 0.942, 0.938
Average = 0.945, highest = 0.971, lowest = 0.926
Tolerances for standard instruments = 0.945 +/- 0.5 % and +/- 0.005 = +/- 0.010
Highest value within tolerance = 0.955
Lowest value within tolerance = 0.935
Make sure that the values are within the allowed tolerances. If not, use the center
measurement mode.
Repeat the procedure using the center measurement, to ensure that the
measured values are now within the required tolerances.
