Rapid glycaemia compared with enzymatic glycaemia

More about the book

The study investigates the reliability of glucometer measurements of capillary blood glucose in emergency departments compared to venous blood glucose levels. Conducted over three months in a medical intensive care unit with 100 patients, the findings reveal a poor correlation between the two measurement methods. This suggests that capillary glucose readings may lead to misdiagnosis, particularly in cases of hypoglycemia, highlighting the need for caution when interpreting these results in critical care settings.
