Procedure for collecting an environmental sample from your garden for testing
On a windy day when it has not rained for 48 hours, place a soup bowl (or similar wide circumference, yet shallow container) on a table or chair so that animals cannot drink from it, out in the garden.
Leave it there from early morning until evening so that the water surface can collect all the dust, pollen, grass and spores in the air (and whatever else blows onto it). At the end of the day, pour this water with its inclusions, into a clean, empty glass jar with a tight fitting lid.
Write a label on the jar with your name and ‘outdoor sample’ and keep it in the fridge until your next appointment when you can bring it in wrapped in a plastic bag in case of leakage.
If you have dust or mould sensitivities, an indoor sample can be collected as well in an area with lots of air movement. Label the jar and keep it in the fridge as with the outdoor sample. The indoor sample is not dependent on any weather restrictions and can be collected on any day, especially useful on a cleaning/dusting day.
Bring the jar in for testing at your next visit.
