The lab will analyze the urine for the ten different substances once they receive the sample. Some diagnostics provide immediate findings by analyzing urine samples on-site. Having said that, most samples will be sent to a lab for examination, which might take a few days. The lab report will tell you how many of the panel were found in your sample.
A positive result for any one of the ten drugs means that you have used that substance within the last year. A negative result does not mean that you are free from drugs, but rather that the sample did not contain any traces of them. People who want to be sure they do not have any of these ten drugs in their system can ask their doctor or nurse for a drug test. It is important to remember that a negative result does not mean that you are clean, but rather that your sample was clean enough for the tests performed.
A drug test can reveal whether you use drugs, but it cannot tell us when you started using them. You may have used drugs since you were young without knowing it, which is why it is important to understand what kinds of drugs are on the list. If you think you might have used one of them recently, make an appointment with your doctor or nurse. They can give you advice about what to do next and help you stop using those drugs.
The collected material (urine, hair, or oral fluid) for a lab-based test is submitted to a laboratory for more stringent examination. As a result, the findings take longer to arrive (2–3 days on average). A lab-based test can detect any substance. It cannot distinguish between drugs that differ only by their chemical structure, such as heroin and morphine. A lab-based test can also give an indication of how much of the drug was present in the body, but it cannot tell you what effect it had on you.
In addition to lab tests, some drugs must be prescribed by a doctor and taken as instructed to be effective. If you stop taking your medication, you run the risk of building up a resistance to it which would make future use ineffective. This could mean needing higher doses or switching to another drug within the same class.
Drug testing has become a popular way for employers to ensure that their employees are using the products they are allowed to have on company property. The process can also help employees understand whether or not they are at risk of being harmed by certain substances. However, drug testing cannot determine why someone might be using or abusing drugs nor can it predict whether someone will commit crimes while under the influence of drugs or alcohol. Employees should be made aware of this fact before they agree to have their drugs tested.
Some jobs may require you to work with drugs outside of office hours.
Depending on the type of test, drug test results often take 24 to 48 hours (e.g., urine, hair, or DOT). Some tests can detect drugs within an hour, but most require several days. Results show up as positive or negative for drugs in your system.
If you fail a drug test, contact your drug testing company immediately. They will be able to advise you on what action(s) you should take next.
It is important to remember that drug test results only tell you if you were using drugs at some point in the past. They cannot reveal whether you used drugs today or even tomorrow. If you have concerns about whether or not you passed a drug test, talk to your drug testing company first before taking further action. They should be able to help you understand exactly what your result means.
Drugs in the blood are often detectable within minutes to hours, depending on the substance and dosage, whereas urine might take one to several days. Blood drug screen tests on whole blood specimens are conducted utilizing immunoassay screening with reflex to definitive testing. The two most common blood-based drug screens are for marijuana (cannabis) using immunoassays designed to detect THC metabolites in the blood; and for opiates using immunoassays designed to detect morphine or other opiate alkaloids.
Other substances that can be detected in the blood include stimulants (amphetamines), depressants (barbiturates), hallucinogens (PCP), nicotine, steroids, tricyclic antidepressants, antihistamines, phenothiazines, beta blockers, calcium channel blockers, and lidocaine. Drug screen tests also are available for prostate cancer patients, those taking HIV medications, and pregnant women. Urinalysis detects drugs not only present in the blood but also passed into the urine. The two main methods used by laboratories to analyze urine for drugs are gas chromatography/mass spectrometry (GCMS) and high performance liquid chromatography (HPLC).
Drug screen results should be interpreted with caution because of differences among individuals in their ability to metabolize certain drugs.
Types of drug testing specimens In urine, illicit drugs can be detected for five to ten days, but hair drug tests can identify drug or alcohol usage for up to 90 days. Blood testing is extremely accurate, but it is also expensive and intrusive. It does, however, have a shorter detection time (minutes to hours). Drug testing programs vary from company to company and some only test employees while others include candidates who submit samples. It is important to know the policy of your company before you start using drugs or drinking alcohol. If you know that you will be asked to provide a sample then you should try not to use drugs or drink alcohol during the period in which the sample will be provided.
If you claim you do not use drugs even though you find out later that you tested positive then you will need to explain this discrepancy. There may be issues with your credibility that could affect your employment prospects or promotion opportunities.
If you are required to take a drug test and don't want to then there are several things that you can do. The first thing you should do is ask why you were selected for testing. Sometimes they will tell you but sometimes they won't. If they won't tell you then try to imagine what might have caused your employer to select you.
