Abstract
- Abstract In this study, levels of inflammatory protein biomarkers in venous plasma, plasma derived from capillary blood from the earlobe, and capillary plasma stored as dried plasma spots (DPS) were compared. Samples from 12 male individuals were assessed with a panel of 92 inflammation-related proteins using multiplex proximity extension assay. Correlations between sample types varied greatly between analytes. A high correlation of ρ > 0.8 was observed between capillary plasma and DPS for 32 analytes. At this level of correlation, 13 analytes correlated between venous and capillary plasma and 5 analytes in the comparison of venous blood with DPS. Highlights • Measurement of an inflammation protein panel in three sample sources. • Earlobe plasma as a less invasive alternative sample source than venous plasma. • Protein measurement in capillary plasma stored as dried plasma spots (DPS). • Correlation value of ρ > 0.8 between capillary earlobe plasma and DPS for 32 analytes. • Correlation value of ρ > 0.8 between venous and capillary earlobe plasma for 13 analytes.
