Introducing Presumptive Drug Detection Technology. The New Generation of Presumptive Drug Tests. What is essential in drug testing is often invisible to the human eye. DTect offers a group of patented drug detection and identification products that provide distinct advantages for in-field testing.

The D4D pen test is a one use, liquid ampoule test for the preliminary detection and identification of four different drugs (at one time) from a single trace sample. The D4D aerosol gives you size choices of 10, 50 or 100 sprays. With each product the on-the-spot reaction ensures a testing process that is convenient, fast and efficient.
