Growth has been driven by demand for its mobile solution, ClearID, and an enhancement to services to bring in breath tests for alcohol and drugs.
MIS revenues were US$1.06mln in July, up 37% on the same period a year ago and are ahead 27% for the year to July 31. They accounted for 47% of total turnover.
"We are proud to have achieved this milestone of over $1 million in monthly revenue for Medical Information Services,” said chief executive Robert Vale.
“We are receiving ever-growing demand as customers increasingly recognise the value that our solutions can add to their screening programmes - to benefit both the employer and the employee.
“We are also pleased to introduce our new combined drug and breath alcohol testing service, which is the first step towards our goal of providing complete medical review services."
