StoneWash was the name of a diagnostic testing product developed by Stone Clinical Laboratories in Louisiana. It was described as a mouthwash-style test for sexually transmitted infections, with an oral rinse forming the basis of the collection concept. The product name brought together the Stone identity and the rinse-based method that defined its presentation.
To understand StoneWash, it helps to know the laboratory that created it. Founded in New Orleans in 2016, Stone Clinical Laboratories operated as a clinical reference lab with an emphasis on preventive and molecular diagnostics. Its services involved analyzing specimens for healthcare providers and working with laboratory methods used in infectious disease testing.
The StoneWash name appeared in product-related documentation in 2018 and in a federal trademark filing submitted the following January. These records establish the product as part of Stone Clinical Laboratories’ earlier diagnostic activities. Its principal historical characteristic was the idea of using a mouthwash-style collection approach within a medical testing service.
