Coagulation results are strongly influenced by pre-analytical variables, mainly blood collection, followed by the time between collection and examination. Having an adequate laboratory quality control is essential to deliver results with the greatest possible reliability.

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. The proficiency test monitors process trends (inaccuracy), commonly related to linearity, specificity, sensitivity, and interfering and calibration characteristics.

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).

These benefits are provided in the laboratory of Controllab quality control programs. Among them, Coagulation stands out. Among them, Coagulation stands out. These are controls with an extensive analytical scope, according to the tables shown at the end of the page.

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 http://www.inmetro.gov.br/credenciamento/acre_prod_ep.asp.

CI programs of Controllab are considered third-party controls. 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.

By enrolling in the CIs, the laboratory has access to the CI ONLINE, the complete management of internal quality controls.
