The importance of pre-analytical variation
Biological samples are inherently variable to begin with, but other factors, such as how a sample is collected, handled, and stored, can further affect analyses and results. In terms of proteomics, improper sample handling can impact the structures and amounts of the very proteins under study.
Controlling for pre-analytical variation is critically important in order to avoid misleading analyses that impact data and cause setbacks and loss of samples.
SomaSignal® tests for pre-analytical variation
SomaLogic has developed a set of tests that can provide an assessment of pre-analytical variation and enable identification of impacted measurements. It could minimize the impact of sample variation when:
- Identifying signatures of disease
- Discovering new drug targets
- Looking for drug response profiles

White paperAssessing pre-analytical variation for more accurate proteomic data
Results are only as good as the samples used to generate them. Good sample in, good data out. In fact, analysis of uncontrolled samples can generate misleading data and cause setbacks in research efforts that cost time, money, and possible loss of precious samples. Biological samples are inherently variable and can differ greatly in their stability. For example, DNA is relatively stable and can often withstand harsh storage conditions. Proteins, however, are particularly vulnerable to inconsistent collection methods, storage temperatures, and processing methods. It is thus critically important to minimize pre-analytical variation when preparing samples for protein assays.See relevant publications in our interactive viewer
