##### will only test for the substances listed in this Paragraph. The first number in parentheses after each substance indicates the threshold for a reportable test result on the initial screening, and the second number indicates the threshold detection level for the confirmatory test: amphetamines/methamphetamines (300 ng/mL, 300 ng/mL); barbiturates (300 ng/mL, 300 ng/mL); cannabinoids in urine (100 ng/mL, 20 ng/mL); cannabinoids in blood (10 ng/mL, 10 ng/mL); benzodiazepines (300 ng/mL, 200 ng/mL); cocaines and/or metabolites (300 ng/mL, 150 mg/mL); phencyclidine (25 ng/mL, 25 ng/mL); opiates (300 ng/mL, 300 ng/mL); methaqualone (300 ng/mL, 300 ng/mL); methadone (300 ng/mL, 300 ng/mL); alcohol (0.08 g/100mL, 0.02 g/100mL).

So according to this guideline, am I correct in assuming that if the person tested here gets below 100ng/mL for cannabinoids they will consider it a pass and test no further, but if they test above the 100 ng/mL they will confirm with a 20 ng/mL test?
