Objectives: This work aims to determine the level of implementation of analytical quality specifications in Spanish clinical laboratories and, in particular, the minimum analytical quality specifications obtained by consensus of the Interdisciplinary Expert Committee on Quality Specifications (CEIEC) in the Clinical Laboratory, as well as to determine the opinions of the professionals as regards establishing mandatory analytical quality specifications.. Material and method: A questionnaire was designed including 4 descriptive, 16 retrospective, and 2 prospective questions. The responses were collected during September to November 2012. The requirement for participating was to be involved in an intercomparison program of any of the 4 Spanish scientific societies represented on the abovementioned committee. A total of 1,738 questionnaires were sent. Results: A total of 340 responses (19.6% over the total) were received. The results showed that 59% of respondents have a formally recognized quality system. The attainment of predefined specifications was checked by 83%, with 68% having a commitment for documented quality specifications, and 64% had made a list with specification values. A majority (55%) is aware of the existence of the consensus minimum quality specifications of the CEIEC, and 49% would agree that these specifications should become mandatory, while 33% did not declare a clear position on this subject. © 2014 AEBM, AEFA y SEQC.

Internal quality control is the procedure used for monitoring the analytical process and to accept or reject the analytical run.There are two models: internal quality control that exclusively uses the control results from the own laboratory, and internal control externally managed, that also uses control data from other laboratories reported to an external organization.Both of them measure the analytical imprecision but are not adequate to estimate neither bias nor inaccuracy (total error).External quality control evaluates the laboratory performance by comparing with other laboratories, through an external organization.There are three models, external quality assessment and proficiency testing which are almost the same and are focused on the analytical process and external quality assurance that applies to all laboratory processes.The three models of external control measure total error, because the control sample (blind for the laboratory) is tested in singleton. At long-term, when all results for one cycle are available, laboratory bias may also been calculated.From the light of legal requirements, good laboraotry practices and papers from widely accepted authors, internal quality control is not and do not substitute external quality control. © 2016.
