Is a negative diluted drug test reportable?
Thank you.
Thank you.
Really? A diluted drug test is an attempt by the employee to tamper with the test and grounds for dismissal.found this online, my guess is no:
"In all cases when a drug test is reported as positive with dilution or positive dilute, it is always a positive drug test. A test result reported as a Negative Dilute is not a positive and should not be a violation of employer policy."
Excellent explanation.Dilute merely means the creatinine (measure of urine concentration) is less than 20 ng/ml.
This happens fairly frequently when you’re properly hydrated.
Normal human creatinine is 100. From something less than 20 to 500 is within “normal”.
Calling what the DOT calls “dilute” a deliberate means to thwart the test is ignorant. It does, however, indicate an inability with current technology to accurately measure stuff in the urine, hence the usual request for a retest.
Labs that are a little more savvy will “normalize” the creatinine to 100. So if your creatinine is 200, divide indicated levels by 2. This accounts for excessive concentration. I don’t believe it is normalized “up”.
These tests require specialized interpretation as they have limits. 49cfr40 requires a “MRO”. And while they’re usually Docs, they really don’t get good training.
The HIMS program has ZERO qualified interpretation of drug and alcohol tests…
Not necessarily. Dilutions almost always result in retests. It's only on subsequent dilutions or positives that we generally took action.Really? A diluted drug test is an attempt by the employee to tamper with the test and grounds for dismissal.
