Abstract:
Blood collection method selection is critical when analyzing blood gene expression. Multiple blood collection methods and sites exist, each with advantages and disadvantages. For human blood gene expression analyses, blood is commonly collected by venipuncture at the antecubital fossa (interior elbow) using a range of vacutainer tubes. Several vacutainer tube types contain RNA-preserving additives, all adequately preserving blood RNA. Most human subjects accept venipuncture, which collects sufficient high-quality blood and RNA suitable for gene expression analysis by RNA sequencing (RNA-Seq). Venipuncture has drawbacks; it requires trained personnel, carries a risk of injury, is time-consuming, and is often unsuitable for in-the-field, at-home, or self-collection. Capillary blood collection by fingerstick is common and widely practiced but not often used for RNA-Seq analysis due to low and variable blood quantity, a lack of blood RNA preservation options, low RNA yields, and variable RNA quality. This study used total RNA-Seq to compare two different fingerstick blood collection, preservation, and RNA extraction methods with a commonly used venipuncture blood collection and RNA extraction method. We demonstrate that fingerstick blood collection produces RNA suitable for RNA-Seq, that each fingerstick method produces results more similar to one another than venipuncture-derived blood RNA, and that each fingerstick blood collection method can distinguish between experimental groups (male and female subjects). While the venipuncture method examined here is generally preferable to the fingerstick blood collection methods, particularly in well-controlled and resourced environments, capillary blood is suitable and useful for gene expression analysis.

The total size of the zip file is 19.2 MB. An .sh file is a script that can be run with the Bash Unix shell. It contains instructions written in the Bash command language. Users can execute the commands an SH file contains by calling the file in a Bash shell. (from https://fileinfo.com/extension/sh). The .xlsx and .xls file types are Microsoft Excel files, which can be opened with Excel, and other free available spreadsheet software, such as OpenRefine. The .csv, Comma Separated Value, file is a simple format that is designed for a database table and supported by many applications. The .csv file is often used for moving tabular data between two different computer programs, due to its open format. The most common software used to open .csv files are Microsoft Excel and RecordEditor, (for more information on .csv files and software, please visit https://www.file-extensions.org/csv-file-extension). The .rmd file extension is associated with the RStudio, an integrated development tool for Windows, macOS (OS X) and Linux operating systems, which allows users to create apps with R programming language. The .rmd file stores R markdown data (for more information on .rmd files and software, please visit https://www.file-extensions.org/rmd-file-extension-r-markdown-data).
