"As expected the average price for a drug test reported by the majority of respondents (67%) ranges between $20-$50. This would vary depending upon the drugs being tested, collection and shipping fees, and Medical Review Officer (MRO) services. The low end cost of $10-$20 reported by 15% of the respondents was most likely in-house instant urine tests."
