What is Oral Mucosal Transudate (OMT)?

Oral Mucosal Transudate (OMT) is a new quick test for HIV. Oral mucosal transudate draws HIV antibodies out of the tissues of the cheek and gum. The virus itself is rarely ever found in oral fluid. Oral mucosal transudate has high concentrations of IgG; saliva has practically none. Oral mucosal transudate comes from the tissues of the cheek and gum; saliva comes from the salivary glands. The special pad is placed between the lower gum and inner cheek and left there for two minutes.
