My uncle wants to get a fabric tested (after washing it from a certain chemical for which prior studies hv been done that it ll be bacterial repellant). He wants to get it tested if it is repellant to corona virus too.
Any idea where virology lab takes fabric as a sample
in india ?
The reports of studies that he has are from china or Switzerland.
