AI Summary

6.0
Neutral

Quest's shift toward higher-value diagnostics, consumer access, and operating leverage supports a stronger growth-and-margin profile, but with DGX above analyst targets and near resistance, investors should wait for proof that pricing and utilization gains can withstand 2027 Medicare reimbursement pressure before adding exposure.
