The Hepatitis C virus is currently one of the main causes of hepatic cirrhosis and hepatocellular carcinoma; it also constitutes one of the main reasons of unsuitability for blood donation among the population. Hepatitis C presents itself as one of the main infectious diseases in the worldwide scenario. The aim of this work was to conduct a comparative study and a analysis of the methods of screening for HCV in blood donors of the Foundation Center of Hematology and Hemotherapy of Pará (HEMOPA) before and after the implementation of NAT test. The methodology used had a quantitative, prospective, with general objectives of descriptive nature approach, and used a technical procedure with pre-existent written registrations in HEMOPA Foundation. There were 125 seroconversions to HCV diagnosed by ELISA, and 176 diagnosed by NAT, associated with chemiluminescence, totalizing 301 seroconversions from April 2013 to September 2014. It was observed in the study that there was a higher rate of seroconversions when the technique of molecular biology was used, which is associated with an immunological test, instead of the ELISA methodology. In the study most people were male, under 35 years old, unmarried, and had complete high school level. It was observed that among the risk factors studied, the “Surgery” one was statistically significant. We concluded that there is an important clue that the combined use of molecular and immunological tests improves security in the process of blood donors selection. |
