For especially high throughput labs, high-SCC cows can be pre-identified from the previous month, then subsampled (0.2 – 1.8mL) for testing before the milk recording samples are tested as normal for the current month.  These subsamples would be chilled overnight before testing using the StaphGold ELISA the next day and reporting to farmers and their vets shortly afterwards. Note that given the chronicity of S. aureus infections, the urgency of S. aureus reporting is not as great, so a one-day delay in reporting is fine.
