ECOFIX is a single-vial stool preservative that is both formalin- and mercury-free. We evaluated the abilities of three commercialGiardia lamblia -specific enzyme immunoassays (EIAs) (ProSpecTGiardia Microplate Assay [Alexon-Trend Inc.], Giardia Test [Techlab], and PremierGiardia lamblia [Meridian Diagnostics, Inc.]) and two commercial direct fluorescent-antibody (FA) assays forG. lamblia (Crypto/Giardia IF Test [Techlab] and Merifluor Cryptosporidium/Giardia [Meridian Diagnostics, Inc.]) to detectG. lamblia in 34G. lamblia -positive and 44G. lamblia -negative stool specimens (determined by traditional examination for ova and parasites) preserved in ECOFIX compared to their abilities to detectG. lamblia in the same specimens preserved in formalin as the “gold standard” for each assay. Of the 34 formalin-fixed positive specimens, the number detected by each assay was as follows:, Alexon EIA, 34; Meridian EIA, 27; Techlab EIA, 29; Meridian FA assay, 31; and Techlab FA assay, 28. Both FA tests and the Alexon EIA performed well with ECOFIX, but the other two EIAs detected fewer positive specimens (the difference was statistically significant with the Techlab EIA) when ECOFIX was the preservative. Use ofG. lamblia cyst antigen from cultured organisms preserved in formalin and ECOFIX demonstrated that the Alexon EIA could detect smaller amounts of antigen in ECOFIX than the other two EIAs could and suggested that cyst antigen is more stable in formalin. We recommend that laboratories use an FA assay or the Alexon EIA if they plan to use ECOFIX as their stool preservative.
