Onsite collections can save you TIME and MONEY. TVM.Bio® believes in building relationships with our clients, not simply conducting “transactions”. When factoring in your employee wages for travel and wait times, your drug test per person could be costing you more than you think. Onsite collections can help maintain the integrity of the drug testing process. When sending an employee offsite for a drug test, there is ample opportunity to try and cheat the test. Onsite drug testing services can help enforce your drug and alcohol-free policy and support a safe working environment.
