Purpose of the test

Marijuana testing is a diagnostic tool used to detect the presence of marijuana (THC) in a person's system. The test can be performed for a variety of reasons, including medical screening, employment testing, and legal proceedings. The following are some of the objectives of marijuana testing:

1. Medical Screening: Although it's not common to screen hospitalized patients for drug use, marijuana testing may be used to assess patients in specialized medical settings, such as psychiatric care and substance use treatment programs. Marijuana use can have adverse effects on a person's health and can exacerbate certain medical conditions. Therefore, early detection of marijuana use through testing can help health care providers effectively manage these conditions.

2. Employment Testing: Workplaces may require that applicants be tested for the use of marijuana and other drugs. Testing is required by federal law in some workplaces, including transportation and other safety-sensitive industries. Employers may also conduct random drug tests to ensure that employees are not using drugs on the job.

3. Legal Proceedings: Marijuana testing may be used in legal proceedings, such as criminal cases or child custody battles, where drug use is relevant.

The value of marijuana testing lies in its ability to accurately detect THC or its metabolites in various types of samples. Early detection of marijuana use through testing can help healthcare providers effectively manage medical conditions and prevent further complications.

Failure to test can have potential consequences such as

- Delayed diagnosis: If a patient is using marijuana but does not disclose it to their healthcare provider, they may receive an incorrect or delayed diagnosis.
- Adverse health effects: Marijuana use can have adverse effects on a person's health, including impaired cognitive function, respiratory problems, and increased risk of mental health disorders.
- Legal Consequences: In some cases, failure to test when required by law or an employer may result in legal consequences such as termination of employment or criminal charges.

Marijuana testing plays an important role in detecting marijuana use and ensuring safety in a variety of settings. Early detection of marijuana use through testing can help healthcare providers effectively manage medical conditions and prevent further complications. It is important to test when needed to avoid potential consequences such as delayed diagnosis, adverse health effects, and legal consequences.

Who Should Get Tested

Marijuana testing may be indicated for various individuals, depending on the setting and circumstances. Below are some of the people who may need to be tested:

- Job Applicants: Some employers require job applicants to undergo drug testing, including marijuana testing, as a condition of employment. This is especially true for safety-sensitive positions such as transportation or health care.

- Employees: Employers may randomly test employees to make sure they are not using drugs on the job.

- Athletes: Athletes may be required to submit to marijuana testing as part of their participation in athletic events. Marijuana use is prohibited by most sports organizations due to its potential performance-enhancing effects.

- Patients in substance abuse treatment programs: Patients undergoing substance abuse treatment may be required to undergo periodic drug testing, including marijuana testing, to monitor their progress and ensure compliance with treatment plans.

- Individuals involved in legal proceedings: Marijuana testing may be used in legal proceedings, such as criminal cases or child custody battles, where drug use is relevant.

Importantly, marijuana testing should only be used when indicated and with the patient's consent. Healthcare providers should discuss the reasons for the test with their patients and ensure that they understand the potential consequences of not taking the test when required.

Blood Test Preparation Guidelines
Time of day
icon
It is recommended to schedule your appointment for blood tests in the morning hours between 7:00-10:00.
Fasting
icon
It is recommended to fast for approximately 12 hours before blood sampling. The last meal of the previous day should ideally be consumed around 6:00 p.m. On the day before the test, avoid heavy and fatty meals as well as alcohol.
Stay hydrated
icon
Drinking water prior to testing can help with sample collection.
Other factors
icon
Tests should not be performed after a sleepless night or intense physical activity. It is recommended to avoid exercise and stress immediately before blood collection and to not smoke. A short rest is recommended.
Medications and supplements:
icon
Blood samples should be collected before the morning dose. Some drugs can interfere with test results. Consult with your doctor whether you can delay your dose because of lab tests.
Biotin supplements:
icon
High doses of biotin supplements can affect test results, causing false elevation or reduction. It's recommended to avoid taking biotin for at least 72 hours before blood collection. If you are taking biotin, inform the personnel collecting the blood so that they can provide specific instructions.
Preparing for Urinalysis Test
Buy container
icon
Buy sterile, disposable urine containers from pharmacies.

You can also buy a container from a diagnostic centre but the price will be higher. Container is not included in the price of the tests.
Time of day
icon
Ideally, collect the first urine in the morning after an 8-hour overnight rest or at least 4 hours after the last urination to prevent functional proteinuria.
Mid-stream Sample
icon
Collect the urine mid-stream, not at the beginning or end of urination, to avoid contamination. The sample volume should be 20 to 100 milliliters, depending on the container's size.
Hygiene
icon
Wash the area around the urethra with warm water, without using any cleaning or disinfecting products.
Fasting
icon
Do not eat or drink for 12 hours before collecting the urine sample. If necessary, you can drink one glass of clean, unflavoured water during this time.
Physical activity
icon
Avoid intense physical activity before providing a urine sample, as it can lead to an increase in protein and ketone levels in urine.
Menstrual period
icon
Women should avoid providing a urine sample during the menstrual period or within two days of its completion, as this can affect the test results due to the presence of red blood cells and epithelial cells in the urine.
Sexual activity
icon
Abstain from sexual activity before providing a urine sample.
Deliver sample
icon
Take the sample(s) to the sampling point on the same day. Storage: Keep the samples at refrigerated temperature (+2...+8°C) until they are taken to the sampling point.
Interpreting Test Results

Marijuana test results are typically available within a few hours to a few business days, depending on the reason for the test and the type of sample used. Below are some key points to consider when interpreting marijuana test results:

- Qualitative vs. Quantitative: An initial marijuana urine test report is qualitative, meaning that it may only show a positive or negative result and not provide additional information about the type and level of specific cannabinoids. However, confirmatory tests can provide quantitative results that measure the amount of THC or its metabolites in the sample.

- Detection Window: The detection window for marijuana varies depending on the type of sample used and the frequency and amount of marijuana use. For example, THC can be detected in urine up to 30 days after last use in chronic users, but may only be detectable for a few days in occasional users.

- Cut-off values: Marijuana testing uses cutoff values to determine whether a sample is positive or negative for THC or its metabolites. These values vary depending on the type of sample used and the laboratory performing the test. For example, a common cut-off for urine testing is 50 ng/mL.

- False positives: Some medications and supplements can cause false positive results in marijuana testing. Healthcare providers should consider these factors when interpreting test results and may order confirmatory testing to rule out false positives.

In general, healthcare providers should interpret marijuana test results in conjunction with other clinical information to make an accurate diagnosis or assessment. Confirmatory testing may be necessary to provide additional information about the type and level of specific cannabinoids present in the sample.
