Achieving excellence though expertise


The External Quality Assessment (EQA) programs are objective evidence of the quality of the analyzes performed in your laboratory. DIAGAST offers you EQA programs with a wide range of analyzes in immuno-hematology, regardless of your technique and your equipment.


DIAGAST has teamed up with the UCIL (Interlaboratory Control Unit), an external quality assessment organization and the EFS (The French Blood Establishment) laboratory, to offer you a large range of unknown results samples.
Each year, four sample delivery campaigns are planned, including analyzes that you can choose according to your needs: ABO-RH1 grouping and RH-KEL1 Phenotyping, Extended Phenotyping, Direct Antiglobulin Test, AntiBody screening, Elution, Antibody Titration, Compatibility Test. (see reference below)

How do our E.Q.A. campaign work?


In France, participation in an External Quality Assessment (EQA) program is mandatory for all analyzes carried out according to Law L.6221-9 and ISO 15189.

The samples are packaged in sampling tubes identical to those used in most of laboratories. Thus, they can be analyzed under the same conditions as the patient samples.


The Inter-Laboratory Comparison Unit (UCIL) is in charge, independently, of the expertise services, analysis and support during each campaign. Likewise, UCIL makes the results reporting according to strict rules of confidentiality. (Learn more)
