B.I.-Methods

Enabling Standardization of IVDr by NMR

Clinical and translational research by NMR israpidly growing and worldwide networks of research groups such as the Phenome Center Network are forming. As a result, there is an increasing focus on standardization to maintain the transferability and reproducibility of the data. Currently there is an emphasis to standardize the following:

  • NMR instrumentation
  • Standard operation procedures
  • Analysis procedures
  • Metadata handling

Now available on the AVANCE IVDr system, B.I.-Methods is the basis for data analysis technology developments and enables standardization of body fluid analysis by NMR.

B.I.-Methods link the IVDr platform with Bruker's automatic data analysis service and contains all automation methods needed for standardized data generation of body fluids. It also includes efficient quality control methods needed when working on human samples and ensures transferability of spectral data generated. While the entire system is for research use only, B.I.-Methods paves the way for possible future use in clinical settings by fulfilling certain requirements for accredition and certification.

B.I.-Methods Includes

  • „„Standard operating procedures for sample preparation
  • Standardized parameter sets for body fluid and quality control measurements
  • Quality control reporting system including validation reports and control charts
  • QuantRefManager fully integrated in TopSpin to manage quantitative calibration of the IVDr system for urine, plasma/serum and CSF
  • „„Automatic configuration of IconNMR according to the requirements of the IVDr system
  • Standardized templates for SampleTrack
  • Module for automatic access to Bruker Data Analysis Server
  • IVDr Data Browser allows an easy management of the IVDr data (spectra and metadata) and enables to select, copy or overlay a part of them

Benefits of B.I.-Methods

  • „„Standardized data generation and high data quality obtained in full automation
  • „„Stringent spectrometer calibration and QC validation including stringent reporting„„
  • Enabling pooling of data acquired at multiple systems into joint databases„„
  • Enabling sharing and co-development of statistical models across laboratories
  • „„Reliable and consistent NMR data generation in large scale studies with long term horizons„„
  • Supporting NMR laboratory network approach including phenome center networks

Purchasing the B.I.-Methods Package

The B.I.-Methods package comes standard with the AVANCE IVDr by NMR system. It can also be ordered to upgrade suitable non-IVDr systems to IVDr or IVDr compatible systems. Installation of IVDr Methods is done by specially trained service engineers as part of the IVDr set up or as upgrade to non-IVDr
systems. This ensure the B.I.-Methods package is correctly installed and the instrument is properly calibrated and connected to Bruker Data Analysis Server.
