Taking a Drug Test
How the Test Works
First Check's patented home drug test kits use patented, tamper-free lid technology for visible, accurate results in 5 minutes.
Before taking the test, users must read all of the content in the package insert. For a list of reactive and non-reactive drugs, see the drug testing guides, which can be found on the Instructions tab within the product pages.
