We did away with those well over 15 years ago. I agree with David and your LIS is doing the work for you.
List out the cost of those labels, even if they are a penny apiece, 2000/month, times 12 months, woo hoo $$$
These labels just add to the cost of getting the blood out the door, not to mention the time it takes to put them on and take them off of units.
The time for change is now! Go for it, 2 weeks after you make the change they will all be saying, "what retype labels"
