What temperature should Cups be stored at?

The cups should be stored at between 2-30 degrees C until the expiration date printed on the sealed pouch. The test cup must remain in the sealed pouch until use. Do not freeze. Kits should also be kept out of direct sunlight. Care should always be taken to protect the components of the kit from contamination. Do NOT use if there is evidence of microbial contamination or precipitation. Biological contamination of dispensing equipment, containers or reagents can lead to false results. Do NOT use after the expiration date.

What is the shelf life?

Cups will last up to 24 months if kept in a climate controlled area.
They should be stored at 2-30 C or 35-85 F

Can you take Urine from a toilet and test?

No. Toilet water will dilute the process and will not work. 

What is the minimum amount of Urine specimen needed for a conclusive test result?

You should always collect enough Urine in the event of a non-negative result.
The lab will require a minimum of 15mL of Urine specimen, but prefers 30mL for Urine testing.

How fast do you ship?

Can I store these cups in the freezer?

No. We do recommend refrigerator or freezer. They should NOT be frozen.  They must be kept between 2-30 degrees Celcius.

Will over-the-counter or prescription medication(s) give a false-positive test result?
Over-the-counter and prescription drugs may cause a positive test results.   American Screening Corp’s (ASC’s) website has a drug search capability for most over-the-counter and prescription drugs.   This search will provide information if an over-the-counter or prescription drug will display positive or non-reactive test results with one of ASC’s products.
Why is there a separate test for Oxycodone if it is an Opiate?
Because Oxycodone is synthetically manufactured opiates that are not directly refined from the opium poppy resin source.  While the chemical chains are similar, the detection of synthetic opiate drugs requires a lower sensitivity detection level than that established for non-synthetic opiates. 
What is the difference between Methamphetamine and Amphetamine?

Both are potent sympathomimetic agents.

Methamphetamine is the parent drug.  It changes into amphetamine in the body.  Both methamphetamine and amphetamine are excreted in the urine.

A positive result for Amphetamine can be interpreted as a positive test for methamphetamine. 

Is it possible for a donor to test positive for THC after exposure to second hand smoke?

No. Urine concentrations of THC for a positive test results are not possible by exposure to second hand smoke.

What is the likelihood that a testing device is defective?

Unexpected test results or failure to obtain test results is the result of user error 98% of the time.This because of:

  • Failure to follow instructions
  • Inadequate sampling
  • Device contamination
  • Failure to use a timer or other user related factor.

The stringent quality control checks and required random sampling methods mandated by the governmental regulatory authorities during the production process of these devices make the likelihood of receiving a defective test device extremely remote.

How do pregnancy tests work?
When pregnant, your body produces human chorionic gonadotropin (hCG), otherwise known as the pregnancy hormone. This hormone is produced when a fertilized egg implants the uterus. Studies show waiting one week after your missed period will typically give the most accurate results.
Can anything interfere with home pregnancy test results?

Most medications do not interfere with home pregnancy test results, including birth control pills. However, a false positive may happen if you are taking any medications that have hCG (human chorionic gonadotropin) in them, like medications that treat infertility.

I want to test for Valium and Xanax, which Drug Test Kit should I choose?

You should choose the BZO (Benzodiazepines) drug test panel.

Which Rapid Drug Test will test positive for Darvon and Darvocet?

The PPX propoxyphene drug test will test positive for the prescription drugs Darvon and Darvocet.

How long does it take to perform the test?

Results from the test are done usually in under 5 mins. These are known as ‘rapid result’ tests. Be sure to read the results within 5 mins, do not interpret the results after 8 minutes, as they are invalid.

Yes, They are the same family.

How can I interpret the results? Positive or Negative.

Test results are indicated by the colored bands on the side of the cup or the bands on each strip. Negative results will show 2 lines. One in the Control region, one in the Test region. Presumptive positive results will show only one line in the Control region.  And Invalid results fail to show a line at all in the Control region. Please note that even a very faint line is a negative reading.


Do poppy seeds cause a false positive drug test?

Poppy seeds and dextromethorphan have been reported to lead to a false positive result for opiates. Decongestants (ephedrine) have been implicated in causing false positives for amphetamines. The body metabolizes codeine to morphine and both substances may be found upon testing.
