The Dräger DrugCheck 3000 consists of two components: an absorbent collector for obtaining a saliva sample, and a test cassette for the analysis. The test cassette contains the buffer liquid and a window with two test strips, which displays the control and test lines. The drug test itself is performed in three easy steps: swab the saliva sample, shake the test kit, wait for a brief incubation period, and then start the test. A colour indicator on the swab disappears as soon as it has absorbed enough oral fluid for a test.
As soon as the control lines appear in the window, you can read the results. If the test result is negative, a line will appear alongside the respective substance class (drug). This means that none of the target substance was detected in the sample. If a line fails to appear next to one of the substance classes, then the result for this substance is positive.
