Drug screening

2018-07-22 01:28:37
Hi, It's not really a health problem but a question regarding conflicting drug screens of mine regarding Fentanyl.My last drug screen came back positive for fentanyl and the drug cutoff concentration for this test was 10ng/mL. Then the next six drug screens came back negative for fentanyl and on the fifth one they changed the Cutoff Concentration to two ng/mL. Could you tell me if that would make any difference in the results? Thank you very much for your help.
