  • Title: Evaluation of the formalin-tween concentration technique for parasitic detection.
    Author: Methanitikorn R, Sukontason K, Sukontason KL, Piangjai S.
    Journal: Rev Inst Med Trop Sao Paulo; 2003; 45(5):289-91. PubMed ID: 14743670.
    Abstract:
    The formalin-Tween sedimentation method was compared with the formalin-ether sedimentation for parasitic detection. Of a total 297 fecal specimens examined, 72.1% were positive. The formalin-tween technique was effective for ascertaining helminths, particularly Ascaris lumbricoides, Trichuris trichiura and hookworm eggs; however it has less capability for protozoa detection. This method is simple, inexpensive, less time consuming and highly sensitive when detecting the parasitic infection, particularly when focusing on helminth eggs.
