• Sample Details Approx 1g of freeze-dried powdered liver tissue.
  • Method Atomic Absorption Spectroscopy or ICP-MS

Overview

The purpose of this scheme is for participants to monitor the performance of their routine testing procedure for the analysis of Tissue Copper levels in dried tissue powder samples.

Result input

Results are returned through our electronic reporting system.

Tissue Biochemistry: µmol per kg dry weight.

Results deadline (from date of shipping)

21 days

PT Report

Authorised report will be published electronically. These will show intended result and results from all participants

Accreditation Status

ISO/IEC 17043 Conformity assessment – General requirements for proficiency testing.

Health and Safety

This material is for in vitro use only, not for use in animals.

Import Permit

It is the responsibility of the participants to check with their customs authority if an import permit is required to import VETQAS® PT samples. If a permit is required, we must receive a valid copy of the permit before the scheduled distribution date. Please note, if we do not receive the permit by the scheduled distribution date the samples will not be shipped and there will be no refund.

Provision of external services

Aspects of the Proficiency Testing schemes may at times be performed by a competent external service provider, for which VETQAS® is responsible.

Additional Information

Fresh liver has a dry matter of approximately 20%. Use 1/5 of the weight of wet tissue normally used i.e. instead of 1g wet tissue use 0.2g dry powder. Please dry the powder using your routine laboratory procedure and then use 0.2g freshly dried powder for the assay. Remember to allow for this in the final calculation. i.e. Results x 5.
