Molecular diagnosis of SARS-CoV-2 at LIORAD-AICA+ laboratories, a one-year work experience

Abstract

Introduction: The increase in the number of cases of COVID-19 in Cuba demanded of new capacities for the molecular diagnosis of the infection. A Laboratory of Molecular Biology for the molecular diagnosis of this disease was installed at the Base Business Unit LIORAD-AICA+ Laboratories in Havana.

Objective: To analyze a one-year work experience in the molecular diagnosis of COVID-19 at the Laboratory of Molecular Biology, LIORAD-AICA+.

Methods: To begin with the molecular diagnosis of SARS-CoV-2 at LIORAD-AICA+, a group of actions were carried out aimed at evaluating the risks, establishing the working areas and flow, and training the work team. Personnel were trained, and procedures and guidelines were drawn up and modified. 

Results: Risk assessment allowed identifying several risks associated with the diagnostic activity, and measures were established to mitigate them. The laboratory personnel received 23 training sessions; and eight procedures and guidelines, and two registers were drawn up. The laboratory processed a total of 125 154 samples in a year.

Conclusions: During the work year, the accurate diagnosis of the disease was conducted at the Laboratory of Molecular Biology, LIORAD-AICA+. This evidences the importance of personnel training and the compliance with good practices and biosafety measures when working with potentially infectious samples.
