FAQs
How do I use the kit?
Instructions on performing the test are included with your test kit. We’ve also included them on the product pages. You can also click here to find out more.
How much of the sample should I use?
A very small sample is sufficient. In general, your sample should be about 20mg or 1-2 drops.
My vial looks empty, can I still use it?
Some of our test kits require very minimal reagent to be effective, while other kits require more. Depending on the kit you buy, there might seem like very little reagent (few drops). Do not worry, as this is intentional. Some kits are designed to have that amount of reagent, and you can still use it.
How reliable are the tests?
While reagent testing is the best method for on-the-spot testing, it is never 100% conclusive. There are many variables that can impact what the reaction looks like. Lighting, impurities, and unwanted substances in your sample may all play a role.
