Article on Effective techniques for extracting information from geochemical data are largely ignored by the industry

In the area of geochemical data analysis techniques and obtaining geochemical extracting information; most mining specialists strongly recommend an approach that goes beyond merely asking the laboratory for geochemical extracting information of a gold test by sampling every meter of the drill core of a trench and using multielement analysis. There, however, exist other methods of geochemical data analysis techniques and obtaining geochemical extracting information. But these are largely ignored by the industry.

As a result of following only one method and technique for geochemical data analysis and obtaining geochemical extracting information, an average geologist is not generally well trained on the necessary techniques and methods. Whenever a request for such data mining techniques analyses comes up, the geologist is short of the techniques and methods needed for geochemical extracting information, including the use of compositional data analysis. This results in failure in the endeavor of extracting all the geochemical data analysis information contained in the data.

Unravelling the DHF, Technical File and Design Dossier

technical

Design History File (DHF), Technical File and Design Dossier are important regulatory documents for a medical device. Design Control and Design History File are regulatory documents for medical devices in the FDA, while the Technical File and Design Dossier serve the same purpose for the EU’s regulatory body, the MDD.

The Design History File

The history of the Design History File is an interesting one. It evolved out of the FDA’s realization, over time and experience; that the major part of a device’s problems was happening during the design stage and change phases, regardless of whether it was a new product or a changed one. This led to the birth of the concept of Design Control, aimed at tracking, monitoring and correcting the design elements at every stage from start to finish.

What should the Design History File contain?

The DHF should contain the following:

Now, the Technical File and Design Dossier

In short and simple terms, one can understand the Technical File and the Design Dossier as the EU’s version of the Design Control and the DHF. In other words, what Design Control and Design History File are for the FDA; the Technical File and Medical Device (MDD) are for the Medical Device Directive.

What should the TF and DD contain?

These files should have all the basic sections needed to support the requirements of the Medical Device Directive (MDD), Essential Requirements (for that product), and the company’s “Declaration of Conformity” for that product:

  • General Information/Product Description/EC Authorized Representative
  • Classification Determination
  • Essential Requirements
  • Risk Analysis
  • Labeling
  • Product Specifications
  • Design Control
  • Clinical Evaluation
  • System Test Reports
  • Functional Bench Testing
  • Lab Testing
  • Sterilization validation (or AAMI TIR 28 Analysis)
  • Packaging Qualifications
  • Manufacturing
  • Sterilization
  • Conclusion
  • Declaration of Conformity
  • Appendix

Differences between the Technical File and Design Dossier

At a broad level, in general terms, while the Technical File is for MDD Class I and Class II a or II b; the Design Dossier is for MDD Class III devices

While Technical Files are retained in the premises of the manufacturer or the Authorized Representative for review of the Competent Authorities or/and Notified Body; Design Dossiers need to be submitted to the Notified Body for review before the product gets its CE-marking.

The Design History File (DHF), the Technical File (TF) and the Design Dossier (DD)

The Design History File (DHF), the Technical File (TF) and the Design Dossier (DD) are core regulatory documents for a medical device. This is how one can understand the central difference between them: the Design History File (along with Design Control), is the most important among the regulatory documents that the FDA requires for medical devices, while the Technical File and Design Dossier are documents that serve the same purpose, however, within the EU’s regulatory body, the Medical Device Directive (MDD). These documents constitute core regulatory requirements within these regulatory bodies.

The DHF on the one hand, and the TF and the Design Dossier on the other, have a lot of similarities as well as dissimilarities with each other. At a basic level, the major similarity between them is their intended purpose, while what they should contain is the main difference between the two.

If US medical device companies seeking to go global have to compete at a global level, they must meet an assortment of product design documentation standards. The Design Control and the Design History File (DHF) are mandated by the FDA’s CGMPs in 21 CFR 820.30, while for the EU; the core requirement is its CE-marking documentation –the Technical File or Design Dossier, as described in the MDD.

A thorough understanding of Design History File, the Technical File and the Design Dossier is necessary

All the complexities and in-depth clarification relating to these subtle matters about medical device regulatory requirements will be unraveled at a two-day seminar that is being organized by GlobalCompliancePanel, a leading provider of professional trainings for the areas of regulatory compliance. John E Lincoln, who is Principal of J. E. Lincoln and Associates LLC, a consulting company and a senior Consultant in the Medical device and Regulatory Affairs areas, will be the Director at this seminar.

This seminar has been pre-approved by RAPS as eligible for up to 12 credits towards a participant’s RAC recertification upon full completion. To register for this seminar, please log on to http://www.globalcompliancepanel.com/control/globalseminars/~product_id=900746?linkedin-SEO .
