The FLOTAC method was also more sensitive in
diagnosing small Trichuris spp. eggs: it identified 98.9% (95% CI:
94.2–100%) of the cases identified using the ether-concentration
method before treatment and 92.7% (95% CI: 84.8–97.3%) after
treatment. Of all standard-sized T. trichiura eggs diagnosed with
FLOTAC, the ether-concentration technique only identified 86.8%
(95% CI: 78.8–92.6%) at baseline and 80.9% (95% CI: 71.4–88.2%)
after anthelminthic drug administration
