Chloride and Other Electrolyte Concentrations in Commonly Available 5% Albumin Products
This study quantifies previously undocumented chloride concentrations of three 5% albumin solutions using biochemical analysis.
Design:
We performed blinded analysis of the electrolyte concentration of albumin samples obtained directly from the national blood supplier (Canadian Blood Services). Two-tailed independent t tests were performed for all possible comparative analyses. Analysis of variance testing was performed for relevant three-way comparisons. Significance threshold was set at p less than 0.05.
Setting:
All samples were analyzed in the core laboratory at an academic hospital associated with McMaster University in Hamilton, Ontario, Canada.
Subjects:
We analyzed 65 albumin samples from three available brands obtained through Canadian Blood Services. They include Plasbumin (n = 21), Alburex (n = 24), Octalbin (n = 20).
Intervention:
Laboratory technologists blinded to product identification measured the concentration of electrolytes, extended electrolytes, lactate, and albumin of each sample using the Abbott ARCHITECT c8000 chemistry analyzer.
Measurements and Main Results:
The mean chloride concentration of Plasbumin, Alburex, and Octalbin, respectively, were 109.4 mmol/L (SD, 1.3), 123.6 mmol/L (SD, 1.3), and 136.8 mmol/L (SD, 0.4). The mean sodium concentration of Plasbumin, Alburex, and Octalbin, respectively, were 139.6 mmol/L (SD, 1.6), 137.3 mmol/L (SD, 2.2), and 149.4 mmol/L (SD, 0.5). The chloride and sodium concentration differed significant...
