RIBEIRO, Steveen Rios  y  FURST, Cinthia. Parasitological stool sample exam by spontaneous sedimentation method using conical tubes: effectiveness, practice, and biosafety. Rev. Soc. Bras. Med. Trop. [online]. 2012, vol.45, n.3, pp. 399-401. ISSN 0037-8682.  http://dx.doi.org/10.1590/S0037-86822012000300024.

INTRODUCTION: Spontaneous sedimentation is an important procedure for stool examination. A modification of this technique using conical tubes was performed and evaluated. METHODS: Fifty fecal samples were processed in sedimentation glass and in polypropylene conical tubes. Another 50 samples were used for quantitative evaluation of protozoan cysts. RESULTS: Although no significant differences occurred in the frequency of protozoa and helminths detected, significant differences in protozoan cyst counts did occur. CONCLUSIONS: The use of tube predicts a shorter path in the sedimentation of the sample, increases concentration of parasites for microscopy analysis, minimizes the risks of contamination, reduces the odor, and optimizes the workspace.
