Certain over-the-counter medications or prescription drugs may cross-react with the Phamatech At Home Drug Test and cause a Preliminary Positive Result.The test will only give accurate results on fresh human urine samples. Old or diluted urine samples may not be suitable for testing.

If you are testing someone else, keep in mind that Phamatech At Home Drug Tests are only as accurate as the urine sample being tested. Samples can easily be “adulterated” (i.e., contaminated or tampered) with common household products such as bleach and other liquids if you’re not closely supervising the entire process.

This test provides a screening result only. It is not designed to determine the actual concentration of a drug, the level of intoxication nor is it to be used for legal purposes.

You can read your results at 5 minutes or as long as a red or pink color is indicated in Results Ready window. Also look for line(s) appeared next to the letter C for Dip Cart Tests.

Disregard all results after 15 minutes or when the Result Expired window is indicated by red.

Phamatech's At Home Drug testing products are more than 99% accurate in detecting specific drugs in urine. The accuracy of the test depends on several factors such as how close to the cut-off level the drug is in your urine, how soon the test was administered after ingesting a drug, and how much of the drug was used or ingested.

No. Any line next to the word Drug or the drug abbreviation (depending on the test you have purchased), no matter how dark or light, is considered a Negative Result and no further testing is required. It is possible that the intensity of the lines will vary among the drugs being tested for due to a variety of reasons such as; how diluted the urine is, the pH or protein level of the urine, or interference from a metabolite in the urine that closely resembles the drug.

The test is working properly as long as a red or pink colored line appears next to the word Control or the letter C (depending on the test you have purchased).The result is Negative when a red or pink colored line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased).The result is Preliminary Positive when NO line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased).If you have questions about your results call 1-877-466-3837 to speak with one of Phamatech's At Home representatives.If you are unsure about your results please re-test using a new Phamatech At Home Drug Test.

Most drugs can be detected in urine with a Phamatech At Home Drug Test within a few hours after taking the drug; however this can vary depending on the type of drug taken, the amount taken, the frequency of use, and the metabolism of the person being tested.Each drug is cleared by the body at different rates. Some drugs, for example marijuana, can stay in the body for up to several weeks after use.

The cut-off level for each drug varies (depending on the type of drug) and is measured in nanograms (ng/ml).

Although Phamatech At Home Drug Tests are designed to detect a very small amount of a drug in urine, if the amount is below the established cut-off level, you may test negative for that drug even though you may have taken the drug.

The Substance Abuse and Mental Health Services Agency (SAMHSA), has set “cut-off” levels when testing for marijuana, cocaine, methamphetamine, amphetamines, ecstasy, opiates, and PCP. Phamatech devices are manufactured to conform to those standards. Screening tests may not detect amounts of drugs in a urine sample that are below the cut-off level. Even though some level of drug may be present in a urine sample, the sample would still be considered Negative Result if the drug level is below the cut-off level.

Many Phamatech At Home Drug testing products are more than 99 percent accurate in detecting specific drugs according to the designated cut-off levels.However, if a more sensitive test is administered, there is a chance of testing positive if drugs are present in urine.
