Randox has launched the first in a series of White Papers, focusing on the importance of quality control in point-of-care testing (POCT). The White Paper is free to download and will help laboratories define an appropriate QC procedure for all POCT devices.
Patient testing at the point-of-care has increased dramatically in recent years, as technology makes it more convenient to test patient samples at the bedside producing rapid results and allowing immediate action. However, the benefits of this are only true if the results are both accurate and reliable, making quality control vitally important in the POC setting, just as it is in the laboratory.
A recent survey* identified that POCT is the largest source of error when compared to other sources of laboratory testing errors. Furthermore, the most common phase for errors in POCT is in the analytical stage, whereas in laboratory-based testing this is the least common source for errors. This highlights how vital it is to have a robust QC procedure in place for POCT as the potential risk of harm to a patient appears to be far greater for POC tests compared to those performed in a laboratory.
The White Paper from Randox covers the fundamentals of developing a POCT QC strategy in line with ISO15189 requirements, looking at who is responsible for QC, what QC is appropriate for different types of POC devices and tips for choosing IQC material and an EQA scheme.
The Paper can be downloaded from the Randox website here.
Randox second White Paper, which studies the importance of using 100% human serum controls to avoid lot-to-lot variations in immunoassay testing, will be available in December.
