  • Safety report and final report development for clinical and pre-clinical studies in accordance with local and international requirements.

The method validation is implemented in compliance with local requirements (Guideline for the Evaluation of Medicinal Products, 2013), FDA and EMA standards and includes the following parameters:

  • Method linear range
  • Lower limit of quantification determination
  • Inter- and intra- day accuracy and precision
  • Analyte selectivity; endogenous level determination if required
  • Analytes mutual impact when multi compound mixtures analyzing
  • Analyte and internal standard recoveries
  • Long-term stability in biological fluids
  • Post-preparative stability of analyte
  • Analyte stability in stock and working solutions
  • Short-term stability
  • Freeze and thaw stability
  • Matrix effects evaluation with assessment that of hemolyzed samples
  • Carryover effect
