Abstract Withdrawal

If you must withdraw an abstract, please notify AACC via email as soon as possible, citing the abstract number, poster number, title, presenting author, and scheduled presentation day. If your abstract must be withdrawn during the meeting, notify AACC staff at the poster desk located outside the poster hall in the Anaheim Convention Center.

Failure to present an accepted poster without prior notification may jeopardize your ability to present at future meetings.

Poster/ePoster Preparation & Requirements

Guidelines are for both physical, in-person posters and ePosters. You should upload the same poster to the ePoster system that you display as a physical poster in Anaheim.

Poster Size

  • All posters can have a maximum size of 46 inches x 46 inches (117 cm x 117 cm).

In-Person Display Board Details

  • The poster number provided by AACC will be placed in the upper corner and measures 8.5 inches long by 5.5 inches high (approximately 22 cm x 14 cm).
  • Pushpins will be provided to adhere posters to designated poster boards.
  • Please note that if your poster exceeds the size limits, it may be cut, folded, or otherwise modified to fit the allotted display room.

Title and Authors

Your title must contain the following information:

  • Poster number as provided by AACC.
  • Title as submitted on your abstract.

  • Background of your study (why you did this work).
  • Method(s) used to achieve a solution.
  • Results obtained (figures, tables, etc.).
  • Conclusions and importance of your work to laboratory medicine.

ePoster and Audio Narration File Formats

All poster presenters are expected to upload their poster to the ePoster platform. You are also able to upload a short audio narration. This narration can be a maximum of 5 minutes. It is highly encouraged, as it provides some substitute to the in-person interaction for people viewing your poster online.

The following are the accepted file formats for your ePoster and audio narration. Any other file format will be rejected by the ePoster upload site.

  • ePoster: PDF
  • 5-minute or less audio narration: M4A or MP3

Uploading Your Files

The ePoster upload site will open the week of May 8, 2023. 

You will receive a notification when it is available. Before uploading your ePoster and audio narration, you will be required to complete a Permission to Record and Reuse form online.

ePoster Submission Deadline: Thursday, July 13, 2023

Important Reminders

  • You must complete the Permission to Record and Reuse form in the ePoster upload site in order for your poster to be included in the ePoster platform.
  • Double check that your audio narration is no more than 5 minutes long. Your file may be rejected during review if it exceeds 5 minutes.
  • If you have more than one abstract, be sure you are uploading the correct ePoster and audio narration files for each abstract.
