WHAT ARE THE BENEFITS OF uscreen pm oral?

The test is objective and easy to run. It can be performed on-site and provides immediate answers. UScreen PM Oral is a one-step process. There is no sample handling or any instrumentation required. It is easily observable and does not require gender-based observation. If there is a non-negative result, confirmation can be performed on the same sample.

HOW DOES THE ORAL FLUID RAPID TEST WORK?

The UScreen PM Oral tests were developed to detect active drugs-of-abuse present in the oral fluid. It is a one-step lateral flow immunoassay device for the qualitative detection of drugs of abuse. The device will indicate if the sample was negative or non-negative. If the test is non-negative, further testing is indicated.

WHAT IS A LATERAL FLOW DEVICE?

Multiple Drug Screen Oral Fluid Testing is based on a competitive immunoassay procedure in which a membrane with immobilized drug derivatives compete with the drug(s) present in oral fluid for limited binding sites on the colored colloidal gold antibody conjugates. During the test, oral is collected at the collection pad and migrates across the membrane. If no drug is present, the colored colloidal gold conjugates will bind to the drug derivatives on the membrane to form visible bands at specific test regions. If a drug is present, it will bind with the colloidal gold antibody conjugate and prevent the latter from binding with the membrane drug derivative so that no drug band will be formed. The lateral flow is the migration and competition across the membrane.


WHAT DRUGS DOES THE DEVICE DETECT?

The test device will detect the most commonly used drugs including amphetamines, cocaine, marijuana, methamphetamines, opiates, and PCP.

HOW DO I ENSURE THE DEVICE IS WORKING CORRECTLY?

The device is easy to use. The test subject should not eat, drink, or smoke for a minimum of 10 minutes before testing. The test subject removes the cover from the device. With the test windows facing downward, the device is placed on the top right side of the tongue for 5 seconds and moved to the left top side of the tongue for 5 seconds. The device is turned over, so the test windows are facing upward. The test subject holds the device between the tongue and the bottom of the mouth until the pink color flows midway in the test windows. The device is removed and placed on a flat surface for approximately 10 minutes until the color bands are displayed. The control band must be present for the test to be valid.

HOW ACCURATE IS THE TEST?

UScreen PM Oral has been shown to be greater than 99.5% accurate when compared to laboratory-based screening and confirmation testing.

HOW WILL I KNOW IF THE ORAL FLUID IS NON-NEGATIVE FOR DRUGS?

The test provides a rapid on-site result. When a subject tests non-negative for a particular drug, there is no band at the drug line. Please note that the control band must be present for the test to be valid.


IS IT POSSIBLE TO ADULTERATE THE TEST?

It is very difficult to adulterate the test. Make sure the subject has not eaten or had anything to drink for a minimum of 10 minutes before testing.

CAN FALSE POSITIVE RESULTS OCCUR?

Any screening test can give a "false positive" result. Confirmation testing verifies non-negative results and rules out other potentially interfering drugs that might have caused a non-negative result.

CAN FALSE NEGATIVE RESULTS OCCUR?

There is less chance to find a false negative result with an oral fluid sample than with a urine sample because of the availability of urine adulterants on the market. In the case of the urine tests, there are adulterant tests to eliminate false negatives. For oral fluid testing, the chance of false negative results is very low as long as the test subject does not smoke, eat, or drink for a minimum of 10 minutes prior to testing.
