Occupational Toxicology Services was established in 2001 as a consultancy service for clients and laboratories wanting to conduct urine Drug & Alcohol testing in accordance with AS/NZS 4308:2001. Occupational Toxicology Services worked closely with J & K Nominees one of the first workplace Drug & Alcohol testing companies in Australia. JK ProCare Systems was established in 2005 as the Victorian collection agency of J & K Nominees.

In 2008, the JK ProCare Systems business was sold to Occupational Toxicology Services Pty Ltd and continues to operate under the JK ProCare Systems name as a drug and alcohol collection and testing agency.

ToxLogic Pty Ltd was established in 2013, encompassing the work of Occupational Toxicology Services Pty Ltd while retaining JK ProCare Systems as a trading name.

Our head office is in Melbourne and we also operate a regional collection centre in Morwell. While most of our clients are based in Victoria, we offer an Australia-wide collection service where this is required by the client. Collections outside of Victoria are conducted either by the JK ProCare Systems staff travelling to the interstate site, or by interstate contractors using JK ProCare Systems equipment and procedures.
