Lymphatic filariasis is an important tropical disease. For disease control, screening by laboratory technique plays an important role. The blood test is routinely used for screening for microfilarial parasites. There are many alternative laboratory techniques for screening. The different techniques might provide different diagnostic properties and result in different epidemiological records; hence, standardization is needed. In addition, it is necessary to analyze on cost for planning for implementation of a laboratory technique.
Here, the authors performed a reappraise on the data of filariasis screening from an endemic tropical area, Myanmar–Thailand border area (GPS location 13.392118426381861, 99.5372683229726). The three alternative studied techniques are (a) thick smear, (b) buffy coat capillary tube, and (c) low-concentration normal saline techniques. The primary data are from the previous study on the diagnostic property, detection rate, of the three techniques, and the data on local cost in USD. The cost–utility analysis is done and the results are shown in [Table 1]. It seems that the cost of low-concentration normal saline technique is the lowest. From incremental cost analysis, low-concentration normal saline technique has an incremental cost per utility comparing to thick smear and buffy coat capillary tube equal to 0.35 and 0.25 USD, respectively.
