Calculation of uncertainties in influence quantities in biological essays

| description | Due to the need of showing the reliability of results from biological essays, such as in health and environmental areas, laboratories have been implementing quality systems, particularly ABNT NBR ISO/IEC 17025 (ABNT, 2001), which include as one of the requirements, the calculation of uncertainty in essays results. It is of common knowledge that estimating uncertainty in essays using organisms, such as animal and vegetal species, is difficult, preventing from meeting that requirement in the standard. The paper shows the calculation of uncertainties in influences quantities in these essays as a tool to allow validating the measuring process, by using the essays performed by Rhodia Environmental Impact Analysis Laboratory and IPEN Ecotoxicology Laboratory as examples.<br>Devido à necessidade de demonstrar a confiabilidade dos resultados de ensaios biológicos como, por exemplo, nas áreas de saúde e ambiental, laboratórios vêm implementando sistemas da qualidade, em especial a ABNT NBR ISO/IEC 17025 (ABNT, 2001) que inclui como um dos requisitos o cálculo da incerteza dos resultados dos ensaios. É reconhecidamente difícil de estimar a incerteza de ensaios que utilizam organismos, como com espécies animais e vegetais o que impede, consequentemente, o atendimento deste requisito da norma. O trabalho apresenta o cálculo de incerteza das grandezas de influências nestes ensaios como uma ferramenta que permite validar o processo de medição, utilizando como exemplos aqueles realizados pelos Laboratórios de Análise de Impacto Ambiental da Rhodia e de Ecologia e Ecotoxicologia do IPEN. |
