Technical Style Guide

• Do not use periods when referring to the US and OUS (outside of the United States).
• Do not abbreviate state names in body copy.

• Use full caps for all acronyms (ACC, AHA, HMO, EMR, EHR).
• On first mention in copy, introduce acronym in parentheses: "the electronic medical records (EMR) software is…"
• When the acronym is better known, introduce the full name in parentheses on first mention: "OSHA (Occupational Safety and Health Administration) monitors workplace safety…"
• Spell out acronyms that may be unfamiliar to the audience (especially in patient materials).

• Punctuation, paragraph breaks (orphans/widows)
• Repetitive word choice
• Run-on sentences, lengthy paragraphs
• Confirm any listed calendar dates against the actual calendar.

• Product names are not possessive.
• Veracyte can be used in the possessive when talking about our culture, capabilities or benefits to build value.

• Use capital AM or PM, no periods, for times.
• If times are both in morning or evening, use only one AM or PM after both times.
• Use each AM and PM for morning through afternoon times.

Example: 1:15-2:15 PM and 11:00 AM-1:00 PM

• Use :00 on hour times Example: 6:00 AM or 4:00 PM NOT 6 AM or 4 PM

• Full sentences have periods.
• Sentence fragments have no periods.

Examples:

• Whitney DH, et al. BMC Genomics. 2016.
• Lee H, et al. CHEST Oral Presentation. 2017.
• Lederer DJ, et al. Interstitial lung disease patient diagnostic journey (INTENSITY) survey. J Thorac Dis. 2016.
