Frequently Asked Questions

Rapid Detect vs CVS / Walgreens: What's the difference when buying in bulk online?

We sell drug tests and have done so for 16 years. Our expertise in customer service is going to get you to the right product faster and with less hassle. When you're purchasing online you need to buy from a company that has a clear understanding, that knows what they're talking about. Would you rather buy from a company that sells drug tests, nail polish, and coffee makers, or buy solely from a company that solely deals with drug tests?

For some of your corporate clients, what are some of the popular drug tests that they buy over time?

Urine drug tests are very popular, drug test cups. Since they're an all in one test kits, everything that is needed to perform the test is within the cup. The test strips, urine collection cup, and a temperature strip. A lot of companies now are also going to the mouth swab drug testing simply because saliva detection time shows most recent drug usage. More employers are concerned about whether an employee is under the influence while on the job. Due to the recent marijuana legalization laws that have been changed with the last few years.

What types of companies buy your drug tests?

Staffing agencies, doctor's offices, construction companies, occupational medicine, drug-free workplaces, corporate safety departments, nursing homes, sober living/halfway houses, probation and parole offices, state and federal government agencies, and drug court.

Are rapid drug tests as accurate as A GC/MS SAMHSA Lab test?

Our drug tests are qualitative, which means it only determines the presence of drugs at detection limits comparable to SAMHSA cut-off concentration. GC/MS, which costs more, quantifies the concentration of drugs in the sample. Given the purposes of most drug testing (pre-employment, post-accident, random) is to detect the presence of drug use and not determine the amounts ingested, our rapid drug test satisfies the needs of almost all Drug Screening Programs.

What is the shelf life on the rapid drug tests? How long will these tests last?

Our test devices have a shelf life of 12 to 18 months from the date of manufacture. The expiration date of each Lot of devices is indicated on each individual foil pouch and can be used until that date. Upon the date of purchase, one should have from 6 to 18 months, to be able to stock and use the product. Unless stated differently on the product page (for example, for short-dated products, we will put the expiration date on that products page).

Do rapid test results hold up in court?

Rapid drug tests provide only a preliminary analytical test result. A more specific alternate chemical method must be used in order to obtain a confirmed analytical result- gas chromatography (mass spectrometry) (GC/MS) is the preferred confirmatory method. Any result taken to court must be confirmed by a SAMHSA certified Lab. SAMHSA's list Of Certified Labs For GC/MS Testing.

Are there any legal medications that can trigger positive results?

Yes. The most common problem is the pseudoephedrine in many over-the-counter sinus and cold medications, which can cause a positive result for methamphetamine. A GC/MS confirmation, as well as an MRO review, is necessary to determine the source of the positive result. Some forms of the drugs we test for may be available legally under prescription as well.

How accurate are the test results?

Laboratory test results for drugs of abuse have indicated a greater than 97% accuracy when used according to the step-by-step instructions that are provided with the test. It depends on the drug and how they're rated. Anywhere from 94%-99% accurate, depending on the drug.

What are the pros and cons of urine tests and swab tests?

The mouth swab tests can detect drugs a few hours up to two days prior to usage. THC found in marijuana is very hard to be determined in saliva. The swab tests are higher priced than urine tests. Oral fluid collection can be observed by a collection agency and has fewer privacy issues then urine testing. Which means the results are slightly more difficult to adulterate.

What is the difference between Methamphetamine and Amphetamine?

Both amphetamine and methamphetamine are potent sympathomimetic agents. Methamphetamine is the parent drug. It metabolizes into amphetamine in the body. Methamphetamine and/or amphetamine are excreted in the urine.

Are Morphine, Opiates, and Heroin the same kind of drug?

Yes, they are all tested using the Opiates(Rapid Response) or Morphine (Instant-View) test. These drugs are from the same family of drugs.

Is it possible to cheat the iCupA.D. drug screen by substituting or adulterating the specimen?

No. The iCupA.D. contains a specimen validity test or SVT strip that verifies the validity of a specimen. The SVT strip checks for oxidants, specific gravity, and pH in the specimen. For example, if someone tries to substitute water for urine, the specific gravity indicator will show an abnormal reading.

How long are the results valid after administering the tests?

The amount of time for results to remain stable varies according to the rapid test device. Please visit our library section or call us directly for more information.

Is there any specific way these products need to be stored? Do they have to be refrigerated?

All drug test devices can be stored at room temperature up to the date of expiration printed on the individual foil pouch. They cannot be stored in extreme heat or cold and must remain sealed in the foil pouch until use.

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

It is always important to collect a sufficient amount of specimen in case of a non-negative result. The confirmation laboratory requires a minimum of 15mL of the specimen but prefers 30mL for urine testing. For saliva, it is 2mL.

Does the product need to be disposed of in any special way, such as a biohazard bag?

Urine and oral drug screens do not pose a biohazard risk and can be disposed of in regular waste receptacles.

Are there products that can be used in the tests to give a false negative? What can be done to avoid this?

Although there are only a small handful of products that can be used to change the result of an impending test, there are validity screens available which can detect these adulterants. Some are integrated into the tests, such as the iCupA.D., which has built-in adulteration available, and we also have individual adulteration strips.

Do you have to confirm a non-negative result? If so, how is this done?

Rapid Detect Inc. strongly recommends that a SAMHSA certified laboratory confirm all non-negative results. Please call us directly for assistance.

Are any of your drug tests FDA Cleared?

Most tests have an FDA 510k clearance except for the products marked "For Forensic Use Only".

Should one have a drug testing policy in place at your business if you're drug testing?

Yes, it will not hold up in court if you do not have a drug test policy in your company.

What is the difference in the panels?

How have recent drug laws changed your business?

A lot of states have medical marijuana that's legalized now. A few states have recreational marijuana. There are starting to be more and more companies that are having to catch up that do not test for THC, which we do provide and some companies still test for it, but they ignore it.

As a professional buyer, what kind of things should I look for when it comes to buying drug tests?

A reputable company that has established itself with a name for quality tests with accuracy levels in the mid to high 90's. The best quality and volume discounts would be a great way to start.
