left there for two minutes. |

The OraSure system draws HIV antibodies out of the tissues of the cheek
and gum. The virus itself is rarely ever found in oral fluid. |

This sample, called mucosal ransudate,contains far fewer contaminants
than typically found in saliva. |

What is the difference
between saliva
and mucosal transudate?
|
| Oral mucosal transudate
has high oncentrations of IgG; saliva has practically none. Oral
mucosal transudate comes from the tissues of the cheek and gum; saliva
comes from the salivary glands. |
