Drug Test - Marijuana Blood
Specimen Type: Blood
Drug Test - Marijuana Blood (Labcorp)
This test looks for Marijuana or THC in a blood sample. Because most drugs are metabolized quickly, blood testing is typically most effective for determining recent use. The detection time for marijuana in the blood can be as little as 12-24 hours but may be longer based on a number of factors including how much a person has taken and how often they take it. Chronic users may have a much longer detection period. In the event of a positive result, this test will provide numerical results.
Marijuana testing is also available as part of a number of discounted panels that look for marijuana as well as other common drugs of abuse. For more comprehensive drug testing, please see our 6 Panel Blood Drug Test, 5 Panel Urine Drug Test, and 5 Panel Hair Follicle Drug Test. For even more testing options, please see our Drug Testing Category.
Turnaround time is typically 5-8 business days but additional time may be required in confirmatory testing is necessary.

Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Please be aware that due to national staffing shortages at the labs, results for drug testing may take longer than normal. Request A Test cannot guarantee turnaround time for test results.
Please note that not all lab locations are able to perform the collections for blood drug testing. When placing a testing order online you will only be able to select from lab locations that are able to perform this type of testing.
Customers testing in the state of California should call their selected lab to verify that they can do specimen collections for a chain of custody blood drug test.
The use of products containing Delta-8-THC may interfere with the results of this test. The amount of time delta-8 remains in the system after use will vary. For accurate results, it is recommended to have not used or consumed delta-8 products for at least 2-3 weeks prior to submitting a specimen for testing.
This test is intended to screen for drugs of abuse and is not appropriate for pain management or therapeutic monitoring. Customers who require pain management testing should consult their prescribing physician.
