Glucometer, a point-of-care testing devices, has been widely used to determine blood glucose level outside central laboratory. Glucometer is also used to measure blood glucose level in primary care unit (PCU). The study aimed to assess the quality of glucose measurement by glucometer in 13 PCU under networking of Saohai Hospital, Saraburi. Two levels of control materials and glucometers were provided for PCU through the study. Thirty assays of control materials of each PCU were calculated for consensus mean. The quality assessment of the glucometer was analyzed against consensus mean and company target value. The acceptance limit guidelines were % CV < 5, % bias < 5, SDI ≤ 2, % TE < 13.25 and Sigma level < 3. The results showed 5, 11, 7, 5 and 2 PCU fell within the limit compared to consensus mean, and 5, 9, 6, 7 and 2 PCU compared to target value. The percentage of measured values fell within ± 15% and ± 20% was 99% and 93% for consensus mean, and 99% and 86% for the target. The results show different number of PCU fall within acceptance limit, however, only 2 PCU meet all guidelines. Therefore, quality control system should be taken into consideration to standardize of using glucometer in PCU.
