LOINC Group Usage Notes

Glucose measurement by point-of-care (POC) versus central laboratory (CL) devices has been well investigated but with inconclusive results. One study using 49 patients in the intensive care unit compared catheter blood glucose results from the CL with fingerstick POC glucose results and found no statistical differences, though POC results were biased slightly higher than the laboratory results. [PMID: 17595363] In contrast, in a study of five different POC devices and two CL instruments, the glucose results of all of the POC devices had higher discordance rates than the two instruments in the CL in both fasting and capillary blood specimens. [PMID: 12880146] Differences in hematocrit and serum carbon dioxide levels can affect POC glucose results [PMID: 10656736] , as can variable levels of creatinine, bilirubin, high arterial oxygen, and pH. [PMID: 17595363] As of 2013, the International Organization for Standardization (ISO) published a revised standard that tightens the accuracy required by manufacturers of POC glucometers. Currently, the devices must produce glucose results that are +/- 20% of the true value 95% of the time. The ISO is proposing to narrow that to +/- 15%.
