Scheme Information Sheets
Birmingham Quality Chemistry POCT
| Scheme Particulars | Indicative Details |
|---|---|
| Accreditation body | UKAS |
| ISO/IEC Accreditation status | ISO/IEC 17043:2023 |
| UKAS Accredited Proficiency Testing Provider No | 7860 |
| Objective of Scheme | Provides EQA coverage for benchtop Chemistry analysers that may be part of a POCT service. Currently most participants are Abaxis Piccolo users. Reports are of a simplified format in comparison to UK NEQAS for Clinical Chemistry to reflect that most participants are not in mainstream laboratories |
