How To Use Our Test Kits

Here you can find our general test kit instructions. Please refer to each product's page for specific instructions as they can vary between kits.

General Test Kit Instructions
  1. Knock the unopened ampoule several times against a hard surface, so the granules, which may be sticking to the inside of the ampoule wall, fall downwards.

  2. Take the top of the ampoule between the thumb and index finger and snap off the top with the ampoule breaker.

  3. Use the spatula to insert the suspect material (approx 20mg) into the ampoule. Make sure the powder does not contain any lumps, as this might influence the results of the test.

  4. Use the spatula to stir the solution well for about 10 seconds. Make sure not to leave the spatula in the ampoule because it will melt if left in the ampoule. Let it stand for 5 minutes because the color will darken slowly.

  5. Carefully shake the ampoule for 5 seconds to make the color homogeneous. Compare the colour from the reagent with the colour line printed on the ampoule.

  6. After use, dispose the ampoules in the trash or glass bin.

Our purity test kits use colour to determine the relative purity as opposed to giving an exact percentage (%) of purity. The reason why at-home drug testing kits for drug purity cannot provide an exact percentage of purity is because they are not as accurate or precise as laboratory testing methods. These methods involve specialized equipment (example; gas chromatography, or mass spectrometry) and highly trained professionals who can accurately quantify the concentration of a substace in a sample. On the other hand, at-home drug testing kits, are designed to provide a general indication of purity rather than an exact percentage. Test Your Poison purity kits use colorimetric reactions which is a simpler technique that relies on visual comparisons and colour charts to estimate the relative purity of a sample.
There are several limitations to consider with at-home testing kits that prevent them from providing precise purity percentages:
  1. Sensitivity and specificity: At-home kits may have limitations in terms of their ability to detect and distinguish certain impurities or adulterants accurately. They are typically designed to detect common substances but may not be capable of identifying all possible contaminants.
  2. Calibration: At-home kits do not go through intense calibration and quality control procedures as laboratory equipment, which may affect the accuracy and reliability of the results.
  3. Sample preparation: In a laboratory, samples can be carefully prepared and purified before analysis, ensuring a more accurate measurement of the drug or substance content. At-home kits rely on small and unrefined samples, which can introduce additional variability into the results.
  4. Quantification methods: At-home kits often rely on subjective visual assessments or simplified colour charts, which lack the precision necessary for determining exact percentages.
It's important to recognize there are limitations of at-home drug testing kits. They don't provide the same level of accuracy/precision as laboratory testing. However, it's crucial to highlight that at-home drug testing kits still serve an important purpose and are better than having no testing option at all. At-home testing give people some level of information about the substances they are consuming which allows for more informed decisions to be made that ultimately reduce harm. While they may not yield exact purity percentages, they can offer a general indication of purity and help users assess the relative quality of a sample. It's essential to use these kits as part of a comprehensive harm reduction strategy, complemented by seeking professional assistance, medical advice, or laboratory testing whenever possible.
