Key takeaways
  • Completing your labs helps your care team understand what your skin needs and how your treatment is working.
  • Get your labs done within 2 weeks of receiving your order. This gives your provider the most up-to-date information before your next visit.
  • Quest Diagnostics has locations nationwide. Booking an appointment is recommended to reduce your wait time.

If your Zest provider has ordered lab work, it is a routine part of making sure your treatment is working safely and effectively. Labs give your care team a clearer picture of what is happening beneath the surface so they can keep your plan on track.

Here is everything you need to get it done quickly and easily.

Finding a Quest Lab Near You

Quest has locations nationwide, and you can search for the one closest to you by entering your ZIP code on their website.

Choose the location that’s most convenient for you. Many sites offer early morning, evening, or weekend hours.

When to Complete Your Labs

We recommend completing your lab work as soon as you’re able, ideally within 2 weeks of receiving your order.

This timing helps make sure your provider has the most up-to-date information to personalize and guide your treatment plan.

Scheduling Your Appointment

You can visit Quest as a walk-in or book your visit ahead of time on the Quest website.

Appointments are recommended, as they are prioritized over walk-ins and can help reduce your wait time.
