>> about

Ricky and Karen Mews have owned and operated RKI for 8 years. Bobi Horn has been an employee for many of these years (and also their daughter!). This family-owned business has offered drug testing and trucking services out of Loyal, WI until February 2022 when Bobi found an opportunity and expanded the drug testing arm of the business to Appleton. 

RKI Drug Testing is looking forward to filling a need in the greater Fox Cities. There aren’t many options for occupational drug testing, and we can help with urine, hair, and oral/saliva testing along with breath alcohol.  Testing is available on site at our location at 308 E. Northland Ave, or we can come on site to your place of business. On site appointments are available below with our online scheduler.

As a small business, we know some of the challenges employers and employees face as it relates to routine and random drug tests, especially in the CDL world. Bobi understands the FMCSA Drug and Alcohol Clearinghouse and the FMCSA Portal very well and can help your company get setup and be compliant. We look forward to partnering with you to meet your business needs!

on site testing benefits:

> Less likely to lose time due to being exposed to air-borne ailments from a hospital or clinic waiting room

> The employee doesn't leave your job site

> Expert training in drug and alcohol testing gives our testers the knowledge and ability to accurately handle the test according        

   specific regulations. Our testers are also trained to spot the various methods in which drug & alcohol abusers attempt to avoid

   testing or alter their results

> No waiting time – your employee can keep working until our tester arrives and informs you they are ready to test

> Less missed work time – testing only takes a few minutes and your employee can get back to work & if your employee is unable to

   provide a sample when the tester arrives he/she can continue working until they are able to provide a sample

> After they have already attempted to test and cannot go, shy bladder employees cannot return to work until they can supply a

   sample. They may be given a bottle of water and kept in sight until they can provide a specimen

> Less likely to be involved in a vehicle accident and cause your company to be liable
