North Kansas City, Mo.-based Cerner (NASDAQ:CERN) is making its second small acquisition in less than a month.

On Monday, the health-care software maker announced that it's followed up on February's purchase of PureWellness with a purchase of clinic lab software maker Labotix Automation.

Cerner didn't disclose financial details on the transaction, saying only that it "is not expected to have a material impact on Cerner's 2013 financial results." Regardless, shareholders dinged Cerner stock by 1.8%, which fell to $91.12 in Monday trading.
