DrugTestNetwork’s online, cloud based software application for drug and alcohol data management includes comprehensive random selection generators to pick employees for random drug testing to meet employers’ drug free workplace policies and to comply with DOT Federal guidelines.
You’ll find 3 ways to generate a random selection for both a drug and an alcohol test when you’re generating a draw for both in a single request.
Double Jeopardy (DJ): The selection count for the substance test must be GREATER THAN OR EQUAL TO the selection count for the alcohol test.
- First, donors are randomly selected from the entire list for the substance test.
- Then donors are randomly selected for the alcohol test from those that were selected for the substance test.
- DJ minimizes the number of donors that report for testing.
If a person wasn’t selected for the substance test, they will not be selected for an alcohol test. The percentage for the alcohol test must be less than the percentage for the substance test. If the percentages for the substance and alcohol test are the same, everyone selected will be picked for both a substance and an alcohol test.
One Test Only : The count for the substance test must be GREATER THAN OR EQUAL TO the selection count for the alcohol test.
- First, Donors are randomly selected from the entire list for the substance test and then removed from the list so they will not be selected for an alcohol test.
- Then donors are selected from the remaining list for the alcohol test .
Both Tests: The count for the substance test must be GREATER THAN OR EQUAL TO the selection count for the alcohol test.
- Donors are randomly selected from the entire list for the substance test and remain in the list as possible candidates for an alcohol test.
- Then donors are selected again from the entire list for the alcohol test. Some people may be picked for one test and some may be picked for both test; hence, the name Both Tests.
