Técnicas laboratoriais de análise de sangue desenvolvidas na secção de hematologia do Laboratório de Análises Clínicas, do Hospital Central de Maputo

Abstract

This internship work was carried out in the laboratory of clinical analysis of the Central Hospital of Maputo. Its main objectives were: to acquire practical skills in performing laboratory techniques of clinical blood analysis and to know how to interpret the results of blood tests performed in the hematology laboratory. The internship took place between the months of October and December, having lasted about 8 weeks with the following schedule: one week in the section of collection of blood samples and the remaining 7 weeks in the Haematology section. During the period of the internship, the haematology section of LAC of HCM, received and processed about 10,000 samples, brought from the wards and external consultations. The processing of samples consisted in analyses of Complete Blood Count, Red Cell Sedimentation and Plasmodium Test. There were 9870 CBC analyses, 5840 erythrocyte sedimentation rate analyses and 3200 Plasmodium tests. Of the samples requested for CBC analysis, 1431 (15%), had normal haematological picture and 8390 (75%) had altered haematological picture. Of those required for Plasmodium (malaria) testing, 5% were positive and 95% were negative. The results of the samples requested for erythrocyte sedimentation velocity (ESR) were not analysed due to the fact that this test is not specific and its interpretation should be associated to several factors such as: clinical condition, age, sex and state of the patient. With regard to the technicians at the site of the internship, there was a lack of compliance with the rules and standards of the laboratory, such as biosafety and laboratory procedures. Throughout the internship, the student was able to acquire knowledge about the objectives cited above.(TRADUÇAO NOSSA)
