Biostatistics for In Vitro Diagnostics (IVD) and Diagnostic Studies
The regulatory landscape for In Vitro Diagnostics (IVD), governed by the IVDR in Europe and FDA regulations in the US, demands rigorous statistical evidence for both analytical and clinical performance. Analytical validation proves that your assay reliably measures the analyte, while clinical validation demonstrates its diagnostic accuracy in the target population. ACOMED statistik is a specialized partner for the complete statistical lifecycle of diagnostic tests.
Our high methodological standard is directly informed by our active involvement in international professional societies for laboratory medicine. As a contributing member of CLSI subcommittees specifically focused on evaluation protocols for analytical performance, we possess firsthand, deep-rooted knowledge of current regulatory expectations and methodological best practices. The FDA and global regulatory bodies heavily rely on these CLSI guidelines (such as the EP series).
Our Core IVD Services Include:
- Analytical Performance Validation: Comprehensive statistical design and analysis for precision (repeatability/reproducibility), analytical sensitivity (LoB, LoD, LoQ), analytical specificity (interference/cross-reactivity), linearity, and stability studies.
- Clinical Performance Studies: Calculation of sensitivity and specificity, positive/negative predictive values, ROC curve analysis, and the determination of optimal cut-off values for diagnostic accuracy.
- Method Comparison: Statistical evaluation of new assays against established reference methods or gold standards.
From early assay development to final regulatory submission (510(k), PMA, or CE-IVDR), our biostatistics consulting ensures your diagnostic tests meet the highest global standards with scientifically sound and regulatory-compliant data.
