# LabLink v2.4 Reference Guide

LabLink is a sample submission portal that is part of Clarity LIMS. LabLink allows end users of the lab (ie, principal investigators, clinicians, external labs) to submit samples to the lab for processing. By allowing end users to submit samples through LabLink, the lab benefits in the following ways:

* Save time and avoid manual errors during sample accessioning by automatically receiving submitted sample information in Clarity LIMS.
* Easily configure LabLink to include sample submission templates and supplementary materials (ie, shipping instructions). End users of the lab use these materials during the sample submission process.
* Provide progress updates and publish files to end users of the lab.

## Sign In to LabLink
