Presently we use Cerner Millennium which has the Label Verify option. However what we did prior to this(infact we still do it to eliminate errors) we had an MT, other than the one who prepared the product, to perform a second check then dispense. If a Tech crossmatch, aliquot, thaw, irradiate or otherwise modifies a product, he has to get another Tech to do a double check and dispense the product.
