Submission Forms

Submission forms must be completed and accompany all samples submitted to Charles River. Prior to shipping live animals, review the Animal Safety Checklist and take the necessary steps to ship them properly. We offer two options for utilizing submission forms to submit samples.

LTM™ (Preferred)

Our online data management platform, Laboratory Testing Management® (LTM™), gives you the ability to generate submission forms electronically as well as schedule your samples for submission. By creating orders ahead of time in LTM™, our laboratory will know when to expect your samples for testing, and you can track your samples online throughout the entire testing process. Access LTM™
