Frequently Asked Questions
How do I power on the ToxDetective testing device?
The power button is on the right side of the reader near the top- just press the little circle button for a few seconds to power on the device.
The unit won’t charge up anymore, what should I do?
Never let the reader fully discharge. Just because the screen is black does not mean the reader is turned off. We recommend charging the unit between uses to prevent the battery from fully discharging. Once discharged it can take a few days of charging for the reader to turn on again.
Can I use my own plastic bags, or do I have to use the ones that came with the system? How do I reorder more?
We recommend using the ANP provided bags (Part Number
ACE-II-BAG, can be purchased directly on www.toxdetective.com).
However, users may, at their own risk, use their own sampling bags.
How much cannabis should I use per test?
We recommend using about 1/2 gram (0.5g) of sample per 5mL of RO wash water.
How does the amount I use affect the test?
The more material sampled, the higher chance of detecting
contaminants. We do not recommend using less than 0.5 grams of sample for a test.
Can I use tap water instead of RO or distilled?
No, you must use RO or distilled water. Tap water may be treated or have unknown contaminants or heavy metals that interfere with the test. RO water is comparable (or better) than distilled water. Distillation systems are not designed to remove chlorine and other chemicals completely from the water. Organics such as herbicides and pesticides, with boiling points lower than 100 °C, cannot be removed efficiently and can actually become concentrated in the product water, which is why it is best to use RO water for the tests.
Why do I have to use both test tickets?
The tickets are sensitive to different contaminants, so you must run both to get a full result. The A ticket is most sensitive to carbamates, the B ticket is most sensitive to organophosphates.
Can I reuse the same test tickets?
No, the tickets are for one-time use.
What if my test ticket is past the expiration date, can I still use it?
The enzymes in the ticket will break down over time and become less sensitive, so you should not use expired tickets.
What is the best way to store tickets?
You should store unopened tickets in their original foil pouches at room temperature.
How soon do I need to use the test tickets after I remove them from the foil pouch?
As soon as possible. Only open the test pack right before you run a test.
What is the best way to dispose of used or expired tickets?
You can throw any tickets in the regular trash.
Can I test edibles?
At this time, no. We are currently developing this capability.
What if I wait longer than 12 minutes – are the results still valid?
Read results at exactly 12 minutes. If you are more than 2 minutes late, discard the ticket and run a new one.
I put the control water in the wrong well, what should I do?
If you put the test sample in the control well, discard the ticket and run a new test.
How important is it to use the exact amount of water?
This is very important! Use exactly 5 drops from the provided pipette!
Will the test tell me which pesticide it detects and how much?
This is a qualitative, broad specturm test. It only gives you a positive or negative result, but will not tell you which compound caused the response or at what concentration.
I got a negative result on the ToxDetective, but when I sent it to the lab it came back positive. What happened?
Lab tests tend to be more sensitive than the Tox Detective, as it involves both extremely expensive equipment and time consuming sample preparation and purification procedures. While the Tox Detective provides a quick test result on site, a lab tests should always be performed in order to confirm the negative results.
What is the level of accuracy of the Tox Detective?
Although the ToxDetective is a great total toxicity trigger sensor test, it gives qualitative, not quantitative readouts. This makes is difficult to compare directly to lab results in terms of accuracy. However, because the Tox Detective will recognize any substance toxic to human health, it may give a positive result that the lab test may or may not detect. Labs must test for each individual compound, while the Tox Detective tests for a broad spectrum of contamination at the same time. That is why it makes the Tox Detective very useful in the field.
Does it matter in which order I put the 001a and 001b test tickets into the reader?
No; you can use either the A or B ticket first, just remember which order you run the tickets and tag them accordingly before reading.
How long does the battery last?
With continuous use, the battery will last at least 8 hours. Once you have finished testing, you should plug the ToxDetective in to charge.
Can I reuse the pipettes?
We recommend using new pipettes for each test. If you reuse pipettes, you may accidentally contaminate new tests with compounds from previous test samples.
Is there a record of my tests?
Yes, you can review all your previous tests by clicking on Review Data from the home screen. Click Preview to swipe between records.
Can I download the record?
Yes, you can download the data to an excel spreadsheet that can be reviewed on a computer. Click General Settings then hit Export. Connect the ToxDetective to a computer via USB (you can use the cord from the charger). Open the files from the device and find the ACEImage folder. In the folder you will find JPEG files of all your results and the excel spreadsheet with your data.
Is it safe to handle the test tickets, or should I wear gloves?
The test tickets are completely safe and there is no need to use gloves during handling. However, you may want to wear gloves when testing material that may be contaminated.
How does environmental light affect the test?
Normal indoor lighting conditions will not impact the tests. However, if testing outdoors, the operator needs to avoid direct sunlight. The light will deactivate the reagents in the test ticket and will cause control errors or false positive results. If testing outdoors, the tickets must be kept in the shade.
Does temperature affect the test?
No, normal temperature and humidity fluctuations should not impact the tickets. However, running tickets outdoors under cold weather should be avoided.
How do you choose which pesticides to test for?
The ToxDetective assays are sensitive to compounds that are harmful to human health. Other types of pest control, like neem oil, for example, are not toxic to humans and therefore, are not detected by the ToxDetective. We are working on making additional tests for other compounds not currently detected by the standard assays. Our test for myclobutanil (a fungicide) was the first product of its kind and is sold as a separate test kit.
Why is there a separate ticket for Myclobutanil?
Myclobutanil is a fungicide and has a different chemical structure to carbamate and organophosphate pesticides that are detected on the original tests, so we needed to develop a different assay to detect this compound.
Why is the MycloScreen ticket more expensive?
MycloScreen is more labor-intensive to manufacture than the regular Tox Detective tickets and uses more expensive components.
When you add new pesticides do you need to update reader software?
No; the Tox Detective does not use a library that needs to be upgraded. If you are interested in testing for a specific pesticide that is not on our published list, please reach out and ask us.
Does the reader and tickets need to be run on a flat surface?
Yes. Tickets should be run on a flat surface to make sure the liquid can travel up to the detection windows in the correct amount of time. After the 12 minute incubation period the ticket may be handled upright and inserted into the reader.
Can I dry and use cannabis has been tested and comes up negative?
It is not recommended to consume cannabis previously used for testing. Use at your own risk.
How many samples should I take from a grow?
As many as you can spare, as the pesticides are sprayed unevenly! It is best to take samples from different locations around the grow to find a potential source of contamination.
Given drift and runoff how often should I sample a field?
This varies based on the grow operation as location and testing capabilities differ greatly, but testing often is always recommended.
Can the reader be tested remotely to make sure it is working properly?
Not at this time.
