I would like to use the Outliers Report from the Lab Reports menu for reporting purposes.

The dataset in question is from a Lab Report uploaded in May; subsequent Lab Reports have also been loaded with samples at the same locations in more recent months (June and July).

I am wondering, if I download the Outliers report from the May Lab Reports, will the Historical Ranges and Confidence Limits be for analytical data up to that report (relevant to that point in time), or would they have been updated to include any new data from June and July?

Also, is it possible to confirm if the Historical Min and Max numbers are presenting Non-Detects as half the value of the EQL? E.g., if Result is < LOR 0.01, Result is converted to 0.005 for the purpose of the Historical Min and Max?

Outlier reports will use all available data at a location at the point in time the report is created. So if you create a report in August and you have monthly data prior to May and in addition June and July too, the outlier report will include all of the data reported - including anything later in time to the lab report in question.

and Yes the historical min and max will display non detects as half of the laboratory EQL
