To block access of a user to the lab, you have the option to block a user by changing the user role or you can remove a user from the lab. Navigate to Manage Groups and click Manage Members. Alternatively, you can also manage group members, including inviting and removing users from the lab, by navigating to Group Members in the Configuration menu.

Click Delete to remove the user from the lab. Note that if this user still has samples stored in the lab, you first get a notification about handling stored samples. Please make sure to change ownership of the samples stored by the user.
