ABSTRACT:
Provided is sampling and testing device for the detection of specific molds, allergens, viruses, bacteria, fungi, and other protein containing substances. Embodiments of the device include a sampling member slideably engaged with a base that contains a lateral flow strip adapted to detect specific analytes of interest. The sampling member defines a solvent reservoir that stores an elution solvent in a fluid-tight manner before the device is used to sample and test environmental surfaces. During slideable withdrawal of the sampling member from the base, the elution solvent stored in the reservoir is automatically released to a wick assembly of the sampling member. The wick assembly includes a wick adapted to receive, distribute, and retain the elution solvent. After a user samples an environmental surface for an analyte of interest with the elution solvent wetted wick, the sampling member is returned to the base where the wick contacts the lateral flow strip contained in the base. The wick transfers at least a portion of analyte and the elution solvent to the lateral flow strip for the colorimetric detection of specific allergens, viruses, bacteria, and other protein containing substances in the sample. The colorimetric results of the test are displayed through a window in the base.
