Variability in potassium/hemoglobin ratios for hemolysis correction.
To the Editor: Because the increase in plasma potassium in hemolyzed specimens is linearly related to hemoglobin concentration (1), knowledge of the potassium/ hemoglobin ratio can allow estimation of the magnitude of increase in plasma potassium. Previous estimates of the potassium/hemoglobin ratio have evaluated only a few apparently healthy volunteers (2–4). Interindividual differences, part...
متن کاملJcb: Correction Jcb: Article Introduction
The following errors occur in this paper. All instances of " JIP " alone should read " JNK-interacting protein " , whereas " JIP1 " refers specifi cally to the JIP family protein also known as MAPK8IP1. The legend for Fig. 9 B should read as follows: " (B) Total neurite length refers to the combined length of processes from a given cell. Means ± SEM from 4–8 experimental sets are shown (*, P < ...
متن کاملA direct-reading bilirubinometer incorporating hemolysis and turbidity correction.
An instrument has been developed by which the bilirubin concentration in serum is determined spectrophotometrically.A readingof the difference in absorbanceat450me and 540 m is obtained. The presenceof hemoglobinor turbidity is corrected for, so that the differential absorbancereading, multiplied by a calibration factor, gives the correct bilirubin concentration. Comparisonswith analysesusinga ...
متن کاملAdvanced Motion Correction Methods in PET ( Review Article )
With the arrival of increasingly higher resolution PET systems, small amounts of motion can cause significant blurring in the images, compared to the intrinsic resolutions of the scanners. In this work, we have reviewed advanced correction methods for the three cases of (i) unwanted patient motion, as well as motions due to (ii) cardiac and (iii) respiratory cycles. For the first type of motion...
متن کاملCharacterization and mathematical correction of hemolysis interference in selected Hitachi 717 assays.
The effect of hemolysis on several assays performed with the Hitachi 717 was quantified by relating the amount of error to the concentration of hemoglobin. Hemolysis interference was judged clinically significant when analyte concentration varied by > 10% from the initial value. Hemolysis interference was significant for alkaline phosphatase, aspartate aminotransferase, alpha-amylase, bilirubin...
