How are we going to gather this information? We can postyou the questionnaires and a saliva pot in which toputthe sample.Theinstructionsforcollectingthesalivawill come with the pot and are also found here. We will provide a reply paid envelope for you to return the questionnaire and saliva pot.
For the skin prick test, breathing test and salivary cotinine we will need to meet you at the hospital either when you come to clinic or on a separate visit. It will take about 30 minutes to do all the tests.
