 *     The reference values were determined by using Trinity Biotech 345-UV reagent at the QC reference Lab.

 **   The positive result assigned by the participants are indicated by red color in the table and the (P) indicates out-of-expected range (i.e. Positive) decision.

 ***  Due to delays in survey sample delivery, which may have been caused by the COVID-19 pandemic, and exposure to extremely high-temperature ( 65.5 degree C ) conditions during transportation, C05 and C22 reports were not included in the total reported counts and excluded from this survey evaluation.
