HPLVD Testing for marijuana is performed to find the presence of the plant’s active compounds or the byproducts of those chemicals’ breakdown (metabolites), which are often found in urine or saliva. THC or THC metabolites that suggest marijuana or prescription cannabinoid usage can be screened for and confirmed by marijuana testing. The inactive THC metabolite (THC-COOH), which lingers in the body longer than THC itself, is what most marijuana tests check for.
Testing For Marijuana Might Be Done For:
Medical Examination
A panel of drug tests used for medical screening may contain marijuana. In order for a person to receive the right medical care, this HPLVD Testing is done to identify any medicines or drug combinations they may have taken. Some hospitals, emergency departments, and clinics no longer include marijuana testing with Hops Latent Viroid Test Kit in their drug testing panels as a result of marijuana legalization in some regions.
If someone meets the following criteria, a medical professional may order drug testing for that person:
Is receiving care in a program for chemical dependency or addiction recovery?
In order to guarantee that someone receiving treatment for chronic pain is taking their medicine as directed
- Displays indications of intoxication or has symptoms that might be drug-related, such as unconsciousness, nausea, delirium, panic attacks, paranoia, elevated body temperature, chest discomfort, respiratory failure, seizures, and/or headaches.
- Is a party to an accident that a doctor at the hospital believes may have been caused by drug intoxication
- Is known to use illicit drugs or is suspected of abusing drugs
- Is eligible for organ transplantation
- Is receiving cancer treatment
- Is pregnant or just gave birth, particularly if it is believed that she may be at risk for drug usage or that her newborn exhibits certain recognizable characteristics.
- Is a life insurance policy applicant being assessed for general health as part of this decision

Forensic, legal, and employment testing
In contrast to medical HPLVD Testing, drug testing used for legal, forensic, or employment purposes uses a different sample collecting process. It is highly regulated how samples are collected for forensic testing, and the custody of a sample is regularly recorded to ensure a legal “chain-of-custody.” A tamper-proof seal is used to shut the container once a sample has been given. Throughout all handling, testing, and storage, the sample is accompanied by a custody and control form. As a result, the sample has an ongoing, legally binding record. Prior to reporting, test findings are often examined by a medical review officer, a particularly qualified and licensed physician.
These are some instances of this kind of testing:
- tests required by the court for those who have been found guilty of using prohibited drugs
- Monitoring or testing a parent during a child custody dispute
- To identify whether marijuana had a role in an accident or crime, such as DUI, forensic toxicology testing may be used to examine various bodily fluids and tissues during a criminal investigation (driving under the influence).
- As part of a broad toxicological screening to identify athletes abusing performance-enhancing drugs, certain athletic programs may test for marijuana.
- An employer may also demand marijuana testing. This also goes under the name “workplace drug testing,” which is a particular kind of forensic testing. Before starting work, randomly, after an accident, or if an employer has a solid suspicion that an employee is abusing drugs, it may be done.
- Drug testing at work is frequent. The U.S. Department of Transportation, the military, and other federal employees must do it, and it is standard procedure in many other sectors.

When did you order it?
Medical Examination
When a person is known or suspected of substance abuse or exhibits signs and symptoms that suggest drug use, such as confusion or other abnormal or dangerous behavior, a healthcare professional may order marijuana testing as part of a drug testing panel during a medical evaluation or addiction treatment. Prior to the start of some insurance plans, HPLVD Testing may also be required as part of regular health examinations.
Forensic, Legal, or Employment Testing
When an employer or other legal entity wants to know if a person has used marijuana, forensic THC testing is done. It might be requested at random or on a regular basis as part of an employment screening, during the recruiting process, or as part of a larger drug test in a forensic or legal situation, including following an accident. Random testing may be required to fulfill probation or monitoring conditions imposed by the court.
What does the test’s outcome indicate?
Both screening and confirmatory tests are interpreted based on a predetermined cutoff threshold, such as 50 nanograms per milliliter (ng/mL) for urine samples, just like other types of lab tests. The test will be recorded as “undetected,” “absent,” or “negative” if a substance is missing or present at a concentration below the threshold. The Hops Latent Viroid Test Kit will be classified as “discovered,” “present,” “presumptive positive,” or “positive” if a substance is detected at a concentration equal to or higher than the threshold.
An first THC screening result that is positive or detectable indicates that the subject may have used weed. Confirmatory testing is generally used to corroborate the results because screening tests are not conclusive. A positive confirmatory test does not indicate when THC was used or consumed; rather, it indicates that the subject had THC or THC-COOH in their bloodstream when the sample was taken.
The source of THC or its metabolites, the duration of exposure, the dosage, or the degree of impairment cannot be determined by testing urine for THC.
Negative results do not always indicate that marijuana usage was not present. It’s possible that the individual’s THC levels are below a certain threshold or that the THC has already been digested and removed from the body.
The amount of time it takes for marijuana to be detected varies greatly based on the metabolism, dosage, and frequency of usage of the user. HPLVD Testing can reveal usage that occurred anywhere between three days and more than 30 days before the test. Heavy marijuana users who consume it often may test positive even after 30 days have passed since their last usage.
Is there anything else I need to be aware of?
Roadside testing for driving impairment caused by marijuana use has become a pressing problem as more states legalize the drug. THC concentrations in the blood drop down fast, and the degree of impairment THC causes varies greatly from person to person, making this a difficult testing challenge. This makes determining a single legal amount of THC in the blood, as is done with alcohol, exceedingly challenging. While THC is now the cannabinoid that is most frequently tested in blood to assess impairment, additional cannabinoids are being studied.
In the absence of a better solution, several states, including Colorado, now employ blood testing and a threshold concentration for THC. In order to determine impairment, they are also doing roadside oral fluid tests. Before these tests can be trusted, there are still a lot of challenges to be addressed.
What other types of samples, including urine and saliva, may be used to test for marijuana?
On blood and hair samples, several labs screen for marijuana use.
By sticking a needle into a vein and extracting blood into a tube, a blood sample can be obtained.
Although hair from other regions of the body may also be taken, hair from the crown of the head is often used for testing.
When the mother’s usage of drugs, such as marijuana, during the last trimester of pregnancy is known or suspected, newborns may be tested. In these situations, medical professionals frequently gather samples of meconium, a newborn’s first bowel movement, shortly after birth. Since it may be obtained right away after birth, umbilical cord tissue has attracted more attention in drug testing after delivery than meconium in recent years.
Can THC testing tell if I’m taking marijuana for medicinal purposes or a prescription drug?
Marijuana obtained with a medical card and marijuana obtained for recreational use cannot be distinguished by THC testing.
Additionally, marijuana tests are unable to differentiate between THC derived from the cannabis plant and THC found in FDA-approved synthetic or purified prescription versions.
Are K2 and Spice, two illegal synthetic marijuana products, the same as THC, and can marijuana testing identify them?
THC is not present in illegally produced synthetic cannabinoids like Spice or K2. These are liquid compounds that may be sprayed over plant material to be smoked or vaporized and ingested using devices like e-cigarettes. Although the compounds are sold as synthetic THC or synthetic marijuana and connect to the same brain receptors, they are not the same thing. Illegal synthetic cannabinoids have unexpected and perhaps fatal consequences on the body, including heart palpitations, seizures, and brain enlargement. These substances won’t be found using tests that are designed to find THC or THC-COOH since they are not THC. It is necessary to use a test that is particularly made to find the synthetic substance in K2 or Spice. Even these tests may not be able to identify every synthetic cannabinoid that could be present in a certain “spice” substance.
Can I test positive for passive smoking?
Yes, although it’s not likely to happen at standard screening cutoffs. Secondhand cannabis smoke has been proved to cause positive drug tests in non-smokers, according to research. But it relied on how much THC was present in the marijuana. Additionally, improved room ventilation reduced THC exposure levels.
Can I lose my job if I test positive for marijuana in a region of the United States where it is legal?
Several states have made marijuana lawful for medical use, whereas fewer states and Washington, D.C. have made it legal for recreational use. Workers of federally regulated companies and U.S. government employees are still not permitted to use marijuana in these places, and state laws may not shield them from termination if they test positive for THC. Additionally, it’s possible that state law won’t defend people whose private employers want to dismiss them for consuming marijuana.
What may result in a marijuana test returning a false-positive result?
Many positive screens are validated by a more focused test since THC screening techniques have been known to produce false positives. It is not always possible to pinpoint the reasons for false-positive screening findings.
In a confirmation test, marijuana metabolites’ chemical profiles are distinctive and unlikely to be confused for many other prescription medications. Ibuprofen might have caused false-positive screening results in earlier testing, but this is no longer the case.
Only drugs that truly contain THC will result in a positive on confirmation testing.
How long after marijuana usage can THC still be shown on a drug test?
THC detection periods are highly variable and are influenced by several variables. These factors include the THC dosage, the frequency of usage, a person’s metabolism, and the kind of sample used for the test. For instance, THC can be found in urine up to 30 days after consumption, depending on the amount consumed.
Why would a medical expert need to watch the collecting of a urine sample?
Some people who are trying to avoid HPLVD Testing will try to submit a commercial product or the urine sample of another person as their own pee for testing. Some legal organizations may demand that the collecting of the urine sample be supervised by a healthcare provider or other professional in order to prevent this practice of sample replacement.
