All authors contributed to the data acquisition, manuscript preparation and subsequent revisions.įunding The authors have not declared a specific grant for this research from any funding agency in the public, commercial or not-for-profit sectors. ARC, RJW, TA and NV collated and the data. The term 'of' has been added so the sentence now reads 'Case summaries of these patients…'.Ĭontributors JH, ALS, STS and RJW implemented, conceived and designed the study. The materials have valuation between laboratories in different systems and allow the laboratory to detect more sensitive variations, which are not perceived in the controls of the manufacturers of the analytical system.īy enrolling in the CIs, the laboratory has access to the CI ONLINE, the complete management of internal quality controls.Twitter notice Since this paper was first published online, a sentence in the abstract has been updated. ĬI programs of Controllab are considered third-party controls.
The EP programs follow the criteria of ABNT NBR ISO / IEC 17043 and Controllab is accredited by the General Accreditation Coordination (Cgcre / Inmetro), under the number PEP 0003, according to the scope published at. These controls serve multiple systems and tests, according to the tables shown at the end of the page. Among them, the PTs of Gasobio, Gasometry and Oximetry stand out. These benefits are provided in the laboratory of Controllab quality control programs. The internal control is performed in conjunction with the routine analysis of patient samples, to validate the results produced after identifying that the analytical system is operating within the pre-defined tolerance limits, especially the precision of the process (reproducibility). The proficiency test monitors process trends (inaccuracy), commonly related to linearity, specificity, sensitivity, and interfering and calibration characteristics Proficiency Tests (PT) and Internal Control (IC) have complementary functions together, they have the central purpose of identifying the presence of possible analytical errors, enabling the laboratory to implement actions to eliminate their causes. Laboratory quality control programs of Controllab promote the reliability of results for multiple exams and allow the monitoring of various routine analytical systems.
