![]() Up to 2 g/dL for hemoglobin values and up to 4% for hematocrits at the lowest protein concentration. However, the iSTAT-1 results were generally lower than the GenS results, with discrepancies ![]() The H/H results obtained with the iSTAT-1 instrument gave slightly less correlation with those of the GenS analyzer (r = 0.978 TheĬorrelation was unaffected when hemodilution was performed with either saline (r = 0.999) or lactated Ringer’s (r = 1.000). Hemocue instrument correlated exactly with those of the GenS analyzer at protein concentrations from 0.7 to 6.2 g/dl. Following H/HĪnalysis, the samples were centrifuged and protein determined in the supernatant plasmas. To mimic hemodilution in clinical practice, samples were diluted with saline or lactated Ringer’s solutions. A series of reconstituted samples was prepared with varying H/H and protein levels. Anticoagulated whole blood was centrifuged to sediment the red blood cells the plasma was removed to serveĪs source of protein for mixing studies. These H/H results were compared to results obtained by our core laboratory hematologyĪnalyzer (GenS). To assess this factor, we measured H/H levels at varying protein concentrations using two POCT instruments: iSTAT-1 (conductivity Conductivity-based methods of blood H/H determinations can be influenced by plasma protein concentration. Point-of-care testing (POCT) for blood hemoglobin and hematocrit (H/H) levels provides rapid patient assessment including
