A qualitative detection system and method for visual verification of the presence of human protein in a biopsy specimen collection bottle is disclosed. The system comprises a lateral flow assay assembly securely contained within the lid of a biopsy specimen collection bottle or secured at the bottom of the bottle. The lateral flow assay assembly comprises components that amplify in color intensity through a chromogenic reaction in the presence of certain proteins. A change in color of the components of the lateral flow assay assembly acts as a visual index to qualitatively confirm the placement of human tissue in the biopsy specimen collection bottle.
