Fig. 3From: Effect of specimen type on free immunoglobulin light chains analysis on the Roche Diagnostics cobas 8000 analyzerComparisons of serum versus EDTA-plasma or lithium heparin-plasma separator tube as specimens for measurement of free light chains showing subset of data. The graphs are scatter plots of data for kappa concentration (a, b; restricted to 400 mg/L or less), lambda concentration (c, d; restricted to 400 mg/L or less), and kappa/lambda ratio (e, f; restricted to 100 or less). The line is the line of identityBack to article page
