Quest Diagnostics's steps

Account settings, Profile, then the pencil next to Personal information. Enter your new name and save. You'll verify your identity again before you can see results.

Have these ready

A copy of your marriage certificate, divorce decree or court order (most companies ask for one).
Your updated driver's license or ID, if you have it. Social Security comes first, then the DMV.
Your account number, and the name the account is in now.
