Conclusion
We propose that POC is included in a protocol for GDM screening that
reserves VPG for when CBG-StatStrip fasting glucose ≥5.1 mmol/L or
2-hour CBG-StatStrip is 7.5-9.5 mmol/L. This would reduce the
requirement for venous sampling and laboratory measurements by 75% for
fasting samples and by 48% for 2-hour samples. This approach may allow
to focus resources on measures to mitigate pre-analytical factors in
samples that do need to be sent to the lab.
It may also improve patient experience with fewer venous blood samples
and quicker results for some women, reduce the overall costs of
laboratory tests and save staff time. Our study is population specific
and applied using POC-Statstrips® in a specific health care setting so
further studies in different cohorts using locally validated POC/lab
analysers are recommended before similar protocols can be implemented in
different healthcare settings.
