POCT testing (also known as instant or express) is done by the donor giving us their urine or saliva sample onsite with results produced within minutes. This testing is used for narcotics and can include alcohol.
Lab-based testing is done by the donor giving us their urine or saliva sample onsite then we place the sample in tamper-evident packaging and ship it to the designated testing facility using Purolator. This testing is used for narcotics and can include alcohol.
BAT testing is done using a breath alcohol device that gives an immediate percentage (%) result.
After providing us with the required sample(s), it will be shipped using Purolator in tamper-evident packaging to the designated lab.
*All of our POCT, Lab-based, and DNA testing is collected and/or performed by Certified Specimen Collectors with confidentiality being our number one priority.*
Qualitative testing uses a solution or smoke and relies entirely on the participant's ability to taste the testing agent; a sensitivity test is performed to see if the participant has a strong or weak sense of taste towards the solution/smoke. Once we know the sensitivity, the participant is fitted with a respirator or N95 mask and a seal check is completed. Then, with mask on, the participant dons a hood into which we spray the testing solution. While the aerosolized solution is in the hood, we will guide the participant through a series of minor exercises designed to test the respirator seal (head movement, talking, breathing, etc). If the participant does not detect any of the solution leaking through the respirator/N95 mask we can be confident that we have a good seal and the correct size of respirator.
At UMS, we use either the Bitrex (bitter taste) or saccharin (sweet taste) solutions. If you cannot taste, *or have sensitivities/allergies to*, Bitrex or saccharin, you will need a quantitative test to ensure the respirator is the correct size.
Quantitative testing objectively measures the amount of leakage (quantity) of particulate or vapours in the mask.
This method is a more precise test that uses a machine instead of your sense of smell and/or taste to determine whether or not you have the proper mask size.
At UMS, we use the AccuFIT9000™ and can test 3M, North, and Miller brand respirators.
