AI Summary

6.0
Neutral

Quest's specialty-diagnostics expansion could lift pricing power and margins through its existing network, but with DGX near highs and valued for continued execution, investors should wait for quantified reimbursement, adoption, and profit contribution from MRD, Alzheimer's, and kidney testing before adding aggressively.
