LabCorp's satisfaction rating has dropped. High price and low-value customer experience have been the primary reasons for the drop in satisfaction ratings.

Quest Diagnostics began to aggressively price its services in the late 1990s, prompting LabCorp to start considering an aggressive pricing program as well.

LabCorp also offers credit and prepaid cards, but these cards are not as widely accepted as Quest's financing programs. Furthermore, LabCorp charges processing fees for testing.
