Expected Results:
|
|
Qualitative screening test. Results will be reported as "not detected" or "screen positive".
|
|
|
|

|
|
| Test Limitations: |
|
This is a screening test. Results are to be used for medical purposes only.

|
|
|
| Additional Information: |
|
A cut-off value of 50 ng/mL is used to determine whether cannabinoids are "screen positive". If a screening test is reported as "screen positive", confirmation and quantitation can be made (at an additional charge) by a reference lab using gas chromatography-mass spectrometry. Please submit an add-on order within 7 days of collection if confirmatory testing is needed.
