• Sample Details 320µl x 24 treated plasma samples (each sample comprises of tubes for AV, BOV, NIL, PWM)
  • Method ELISA (eg Bovigam Gamma IFN ELISA)

Overview

The purpose of this PT scheme is for participants to demonstrate that they are able to detect the presence and levels of interferon gamma in plasma samples, using ELISA methods. Each sample includes 4 different stimulation conditions – NIL, PPDA, PPDB and PWM. The scheme may also include duplicate samples and negatives in the panel issued.

PT Report

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

It should be noted that the intended results are based on the APHA methodology and the interpretation criteria used in the UK. ‘Incorrect’ returns might reflect the application of different interpretation criteria or different testing strategies and might not, necessarily, indicate test failure.

Health and Safety

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.
