Effect of repeated freeze/thawing of household dust extracts on β-(1,3)-glucan levels.

β-(1,3)-glucan exposure from household dust has been shown to be associated with respiratory symptoms and thus is increasingly being measured in epidemiological studies. Various factors are known to influence its measurement; however, no studies have assessed the effects of sample extract freeze-thawing on β-(1,3)-glucan. The aim of this study was to assess… (More)
