Immediate Response

The Immediate Response Mobile Analysis (IRMA) blood analysis system (Diametrics Medical Incorporated, St Paul, MN, USA) is a new point-of-care testing device that uses technology similar to the Gem Premier (Mallinckrodt Sensor Systems Incorporated, Ann Arbor, MI, USA), which are ion-specific electrodes. We compared these two analysers using both patient blood samples ( n = 50) and aqueous quality control solutions ( n = 45). Linear regression (Pearson product-moment correlation coefficient) was performed to quantify the strength of the association between results. In addition, bias and precision were determined in accordance with the method described by Bland and Altman.1 The results demonstrated excellent correlation between the IRMA and the Gem Premier, and bias and precision were acceptable for both patient and quality control samples. Reproducibility of results was also assessed using one level of aqueous quality control solution ( n = 50). The IRMA demonstrated very little variance in parameter readings over a five-day study period.

AbstractBlood tests provide crucial diagnostic information regarding several diseases. A key factor that affects the precision and accuracy of blood tests is the interference of red blood cells; however, the conventional methods of blood separation are often complicated and time consuming. In this study, we devised a simple but high-efficiency blood separation system on a self-strained microfluidic device that separates 99.7% of the plasma in only 6 min. Parameters, such as flow rate, design of the filter trench, and the relative positions of the filter trench and channel, were optimized through microscopic monitoring. Moreover, this air-difference-driven device uses a cost-effective and easy-to-use heater strip that creates a low-pressure environment in the microchannel within minutes. With the aforementioned advantages, this blood separation device could be another platform choice for point-of-care testing.

Abstract We evaluated a new portable instrument, the PPG StatPal II pH and Blood Gas Analysis System, designed for "point-of-care" measurements of blood gases and pH. Inaccuracy (% of target value) and imprecision (CV%) were assessed by blood tonometry and comparison with a Corning 178. Within-day results for PCO2 inaccuracy and imprecision ranged from 98.2% to 102.9% and 3.3% to 3.9%, respectively; for PO2, these were 95.5% to 102.3% and 2.3% to 3.0%, respectively. Between-day results for PCO2 inaccuracy and imprecision ranged from 99.2% to 99.3% and from 2.9% to 3.2%, respectively; for PO2, the ranges were 96.2% to 98.2% and 2.6% to 3.0%, respectively. Two PCO2 outliers (in 645 samples = 0.3%) were observed. In general, tonometry recovery, measurement stability, and pH bias results for the StatPal II and Corning 178 were comparable. We conclude that the StatPal II performs within acceptable ranges of inaccuracy and imprecision.
