When we talk to a client on the phone when they call us, it is to understand what their questions are and what their concerns are and then we will come up with a sampling strategy to answer their questions. And it would be at that point that we would decide whether or not just knowing what the genus level name is, like aspergillus or penicillium, will be adequate or if they need to go more deeply and learn about these species. It is more expensive to do a species analysis than it is to do something to the genus level in the analysis. And cost is always a concern, that's a trade-off between what you're learning and the cost of doing it.
We look at it as if we're painting a picture and every sample that we take adds a color, adds a line, adds some detail that allows you to understand what the picture is. So we have to understand what we're looking for to begin with and then we can design a sampling strategy that we believe will give us enough information to make out what the picture is without necessarily incurring the cost of making a Rembrandt or some very expensive set of sampling.
So doing a more comprehensive inspection and taking enough samples to really understand what's going on in the environment is very important. Otherwise you're going to be making choices that you either might be doing less than what you need to do or you might be doing more than what you need to do.
You could have a situation, for instance, where you had a spike in the some kind of air samples for some reason or whatever but no history of it and making a decision wrong in that direction. Or, if someone doesn't take the samples in the right kind of samples and someone has a health problem and you don't identify it, you could be making choices that could be adverse to their interest there.
