Two hundred and sixty-one participants gave all the information requested, and went on to register on the EQA
site and complete the process.

Only a few reports on EQA
in porphyria-related analyses have been published (24-26).
Examination of the results from the repeat study in 2009 shows that the relationship of the ALTM with the reference method is little changed; this is further confirmed by the 48 EQA
results from the LC-MS/MS method.
This approach has been used in other dedicated EQA
schemes, and a review addressing this issue in detail concluded that C37 sera are commutable for many analytes (15, 30, 31).
The purpose of using TMA design for EQA
samples for PT for class II IHC tests is to measure not only analytic performance of the laboratory (eg, signal to noise ratio, intensity of staining, morphology) but also to measure test performance quantitatively by testing multiple samples with a range of expression levels reflecting those encountered in practice.
External proficiency testing programme (EPTP) enlists the procedures adopted for functioning of an EQA

Furthermore, 99% of the Norwegian primary care offices and all hospital laboratories voluntarily participate in the same EQA
programs through the Norwegian Quality Improvement of Primary Care Laboratories (Noklus) (www.
Carpathia's team of experts and engineers worked closely with DHVI to evaluate application, user and security needs and then architect a custom solution designed to meet the NIST and HIPAA compliance requirements required to support the EQA

After familiarizing themselves with the recordings and transcripts, the EQA
and an additional coder created broad categories, and each unit of the transcript was assigned to one or more categories.

program, laboratories can assess their performance through alternative assessment activities, such as exchanging samples with another laboratory performing similar tests, or by internal assessment.

Each antibody was evaluated by an independent EQA
body, NordiQC, to define staining performance in comparison with leading equivalents from other manufacturers.
