Quality evaluation on thick blood film and diagnosis of brugian filariasis

Abstract

The purpose of this evaluation study was to develop quality control of thick blood films (TBF) for diagnosis of brugian filariasis in areas where targetted for National Program to Eliminate Lymphatic Filariasis by fiscal years 2002-2004. In the area stratification of the authorized sectors, Vector Borne Disease Control Center (VBDC) 11.2 (Nakhon Si Thammarat) and VBDC 11.3 (Surat Thani) that governed the PELF's implementation in transmission areas, all 781 TBF were used to grade quality of the standardized TBF. Seven hundred-fifty seven TBF (96.93%) were considered to meet the criteria before the study was conducted. After a short course of field training in standardization and quality control of the TBF diagnostic tests to the 23 field workers from the VBDCs.Then re evaluation to quality control in September,all 360 TBF. It was more likely to show up-level quality of the TBF, ie no standardized 348 TBF (96.67%). For TBF diagnostic had not incorrect. Findings suggest that, in order to improve hand-on skills of the field workers with up-level efficiency in such routine activity, the more they would have perception of diagnosis the disease as part of the PELFS implementation and the more they would perform well.
