In-Home Drug Testing Fairbanks, AK I Instant, Accurate, Convenient (2023)

FAQs

What is the most accurate drug test available? ›

Blood testing is expensive and invasive, but is the most reliable for determining if the individual is under the influence of drugs or alcohol right now.

The At Home™ Drug Test, 99% accurate, 100% confidential.

For the most accurate results, take a home pregnancy test after the first day of a missed period. Check test results too soon. Set a timer to go off at the time the test directions say you should check the result. Don't check the test until that amount of time has passed.

Pitfall: Rapid tests are reliable but they only provide a preliminary sign of drug use. Rapid tests are “qualitative,” which means they determine only the presence of drugs.

What is the detection window for a lab-based, urine drug test? A: Urine drug testing typically detects recent drug use in the previous 24 to 72 hours.

Urinalysis – A urine test is the most common form of pre-employment drug testing and is typically conducted once a conditional offer of employment has been sent. A urine test can show traces of drug use even after the effects of the drug have worn off and remain in the body for an extended period of time.

Overall performance of at-home COVID-19 antigen tests

However, at-home COVID-19 antigen tests are generally expected to detect the SARS-CoV-2 virus at least 80% of the time when someone is infected. When you perform an at-home COVID-19 antigen test, and you get a positive result, the results are usually accurate.

How accurate are these tests? The at-home testing part of this test is fairly sensitive to the presence of drugs in the urine. This means that if drugs are present, you will usually get a preliminary (or presumptive) positive test result.

If two lines appear, including two faint lines, the test is negative. If only the control line appears, the test is positive. Areta's 14 Panel Drug Test Cup Kit is more than 99% accurate. It has been cleared by the FDA for home use and has a Clinical Laboratory Improvement Amendments waiver for professional use.

Urine and blood drug tests are both typically more accurate than saliva—but again, they must be used correctly. A study comparing urine and saliva drug tests found that urine drug testing was more likely to detect overall substance use than oral testing.

What is the difference between instant and lab drug test? ›

Unlike lab-based drug testing, POCT or instant drug testing requires a subjective assessment of the result (e.g., the tester must decide if the test is negative or positive based on visual clues), while laboratory-based drug testing is objective.

An instant drug test typically uses urine or oral fluid (saliva) for the test specimen. The test usually screens for some combination of the following: amphetamine, barbiturates, benzodiazepines, cocaine, marijuana, methadone, methamphetamine, opiates, oxycodone, PCP, and propoxyphene.

Rapid tests performed at Labcorp patient service centers (PSCs) that screen negative have results available to the ordering client typically within 4 hours. Labcorp's certified laboratories provide mass spectrometry confirmation for non-negative rapid test drug screens.

Is a DOT Drug Test Refusal the Same as a Failed Drug Test? Refusing to take a drug test has the same consequences as failing a DOT drug test. Your employer must immediately remove you from safety-sensitive duties, per DOT regulations.

If you're having only a urinalysis, you can eat and drink before the test. If you're having other tests, you might need to fast before the test. Your health care provider will give you specific instructions. Many drugs, including nonprescription medications and supplements, can affect the results of a urinalysis.

Key takeaways: Delta-8 THC is a chemical found in cannabis with similar effects to traditional (delta-9) THC. Because delta-8 THC is similar to delta-9 THC, it can make you feel high and is likely to show up on a drug test. Delta-8 THC is federally legal, but it isn't regulated.

The half-life of Delta 8 THC has been reported as anywhere from 40 minutes to 7 hours. Delta 8 THC can linger in the body much longer than other metabolites and it is generally believed that Delta 8 remains detectable in the body for one to three days after consumption.

Drug testing specimen types

Illicit substances are detectable for only five to 10 days in urine; whereas, hair drug tests can detect drug or alcohol use for up to 90 days. Blood testing is very accurate, but costly and invasive. It does have a shorter detection period (minutes to hours), however.

Should I trust the results of a self-test? Positive results from self-tests are highly reliable. Negative results from self-tests do not rule out SARS-CoV-2 infection. A negative self-test result may not be reliable, especially if you have symptoms associated with COVID-19.

Can you test positive then negative? ›

If a symptomatic person tests positive on a rapid test, they likely have COVID-19. If you are exposed to someone who has COVID-19, or have symptoms but receive a negative test, you should take another test in 48 hours. If you then test positive or if your symptoms get worse, contact your health care provider.

If you no longer have symptoms after five days or are fever-free for at least 24 hours without using a fever-reducing medication, you do not need to take another COVID-19 test to confirm you are no longer positive, unless you have been directed to by your workplace or school.

No drug test of this type is 100% accurate. There are several factors that can make the test results negative even though the person is abusing drugs. First, you may have tested for the wrong drugs. Or, you may not have tested the urine when it contained drugs.

Unlike lab-based drug testing, POCT or instant drug testing requires a subjective assessment of the result (e.g., the tester must decide if the test is negative or positive based on visual clues), while laboratory-based drug testing is objective.
