On (b)(6) 2020, the customer reported that they have been getting all positives on their runs.Technical support requested the instrument serial number, lot numbers and raw data files from the customer.Customer repeated runs on rotagene which is a closed system and all samples reported correct results, but all 96 samples were positives on magpix.This started on (b)(6).Customer repeated run again with 48 samples leaving strips in between.All samples were positive however, controls worked fine as desired.Customer confirmed there were no process changes between extraction and running samples on the magpix.Customer has tried different sets of pipettes but all positives again.Nec is from the same extraction and it is clean.Ntc is also clean but this is just water.Luminex mas director reviewed the results and indicated that customer has probably contaminated their extraction system or reagents/area/equipment.Also, it was determined that they are treating nec different than sample.
