How does the test work?

Answer: The DTN Home Drug Test Device resembles a credit card in size and shape; you dip it into the urine sample and the results read as easily as a home pregnancy test. The device will indicate whether the urine was "negative" for the targeted drugs or "Positive", meaning the device reacted with something in the urine.

How Accurate is the test? 

Answer: The DTN Home Drug Test has been proven to be greater than 96% accurate when compared to laboratory based screening and confirmation testing.

Will I know if the urine is positive?

Answer: The purpose of the DTN Home Drug Test Device is to tell you immediately what the results are.  2 lines means negative (No matter how faint the lines are) and 1 line means positive.

Is it possible to fool the test? 

Answer: There are ways to taint a urine specimen to render it either "negative" for drugs or "unsuitable for testing" on all screening tests.  You can give little or no notice before administering the test, thus reducing the chance the donor will have time to alter the urine.

How long do drugs stay in your system?

Answer: Each drug is cleared by the body at different rates. Any or all of the following contribute to the length of detection: the amount of drug taken, how frequently the person takes the drug, how the drug was taken (smoked, snorted or injected), the metabolic rate of the user, fluid intake and age of the user. A general guideline for detection is as follows:

DRUG	MINIMUM DETECTION	MAXIMUM DETECTION
Amphetamine	2-7 hours after use	2-4 days after use
Methamphetamine	2-7 hours after use	2-4 days after use
Cocaine metabolite	1.25-4 hours after use	2-3 days after use
Marijuana (THC)	6-18 hours after use	Up to 28 days after use depending on frequency
Phencyclidine (PCP)	7 hours after use	3-5 days after use
Opiates (codeine/morphine)	2.5 hours after use	2-3 days after use

Can false positive results occur?

Answer: Any screening test can give a "false positive" result.  All screening tests are subject to potential interference from substances such as prescription diet medications and other compounds that are chemically related to the target drug.

Can false negative results occur?

Answer: A false negative can occur for a number of reasons including the following:

1. The urine sample has been tainted or diluted to the degree that the test reads as negative even if drugs were present (see "Is it possible to fool the test?" question).
2. The concentration of the drug in the urine sample is lower than the amount needed to be detected by the test.
3. A drug is detected by the screening device, but it wasn't one of the drugs detected in the confirmation analysis. An example of this is the drug hydrocodone which is found in Vicodin. Hydrocodone is a member of the opiate family and a urine sample containing enough hydrocodone will trigger the DTN Home Drug Test to indicate an "inconclusive" result. Unfortunately, the confirmation test is specific only for codeine and morphine. So the urine containing hydrocodone will be resulted by the laboratory as a "negative" sample.

If you have observed behavioral changes which you feel could be the result of drug use, don't discard the thought just because the test indicated a negative result.
