22) Thus, the use of plasma hemoglobin as a marker for in vitro hemolysis will not account for erythrocyte potassium loss due to shear stress during blood collection that does not result in complete cell lysis.
The ability of automated analyzers to measure plasma hemoglobin in patient blood samples has proved to be an efficient and reliable means for identifying in vitro hemolysis.
100 g of plasma hemoglobin per deciliter, are considerably different.
This index value corresponds to a plasma hemoglobin concentration of approximately 0.
They considered samples with plasma hemoglobin concentrations greater than 0.
The multitude of factors that can affect erythrocyte potassium loss suggests that the use of correction factors based on a semi-quantitative measurement of plasma hemoglobin is an overly simplistic solution to a complex process.
Plasma hemoglobin measurement techniques for the in vitro evaluation of blood damage caused by medical devices.
We attributed the apparent plasma Pb contamination in a single sample from one subject to lysis of erythrocytes during sample collection and processing, based on a measured plasma hemoglobin level of 20 mg/dL.
In light of the above results, we explored whether variation in plasma hemoglobin levels could explain some of the variance in plasma Pb levels in the study subjects, under the assumption that mild hemolysis could contribute to increasing plasma Pb levels without discernibly increasing plasma hemoglobin levels.
Descriptive summary values for the subjects, including plasma Pb, whole-blood Pb, and plasma hemoglobin and total Fe levels.
The laboratory determined the plasma hemoglobin concentration before analysis.
