Laboratory Testing Variability at Jacob Trott blog

Laboratory Testing Variability. What can cause variance in laboratory testing results? It’s not uncommon for results to vary when taking a repeat lab test, even if both. Even after the standardization of all potential sources of laboratory error, including specimen collection, transportation, preparation,. Of the 22 lab measurements that were evaluated for uncertainty and accuracy, 15 (68%) showed significant interservice variability. Analytical and biological variability can be summarized in the concept of changing reference when evaluating changes between two laboratory. Cv indicates variability of the test results. This depends upon the test methodology, the instrument being used, and the range of results. The quantitative results (continuous variables) provided by laboratory measurements are affected by two main sources of variability:. Bias is the systematic deviation of laboratory test results from the actual value,. The “reference change value” (rcv) allows you to decide whether a change in two serial lab results is likely due to chance alone.
