The firm's flow cytometry business contributed about $13.2 million, or 16 percent of the firm's consolidated revenue in the second quarter.
The firm said its assay is a real-time qPCR test for the direct detection of methicillin-resistant Staphylococcus aureus DNA in nasal swabs.
The test, called ColoPlex and being developed using the xMAP technology, is a blood test that uses multiplexed immunoassay technology and machine learning.
The firm has three clinical trials in progress to validate the clinical utility of products it soon intends to submit for regulatory clearances to the FDA.
The firm said that it placed about 50 sample-to-answer molecular systems under contract during Q1, and it had about 625 active sample-to-answer product customers.
Luminex has since fixed the problem with a software update but a similar issue with non-specific amplification has also affected two targets on BioFire's GI panel.
The number of gainers outpaced decliners 21 to six, and the index outpaced the Dow Jones Industrial Average, the Nasdaq Composite, and the Nasdaq Biotech.
Excluding a loss of business to LabCorp, total revenue increased 22 percent year over year in the fourth quarter, Luminex said.
