  • a Microarray summary statistics were calculated using GeneSpring (version 7.3.1) and Microsoft Office Excel 2003 software. Raw fluorescence intensities from the average of triplicate arrays were used. Replicate dried-blood spots were collected from a human donor. These samples were run on the CIM10Kv2.0 library.

  • b The correlation between the dried-blood spot and the fresh serum is the Spearman correlation, which considers only the relative rank of array features.

  • c NA, not applicable.
