This K3 PreScreen Plus Dip Card has been developed to prevent the spread of synthetic marijuana. The use of synthetic marijuana has continued to grow with dangerous side effects and outcomes. This has led to the need of performing prescreen drug testing for the dangerous drug. This dip card uses the easy and successful “Dip and Read” testing. The dip card has to be immersed in the urine sample for only 20 seconds. Your test results are available within minutes. Afterwards, the results of this dip card are able to remain stable for 60 minutes.
