Laboratory Testing
Phoenix
124 businesses listed, showing 121–124. How we order them.
Phoenix has 124 laboratory testing listings, and two ZIP codes lead: 85032 and 85034 each hold 13 entries, followed by 85003, 85013, and 85027 with 7 apiece. Those clusters are a fine starting filter if you're picking where to look first, but a nearby lab isn't automatically the right one, so call two or three and ask about the specimen type or turnaround you need before you drive over. Of the full list, 120 listings show a phone number and 102 show a website, so most give you a direct way to reach out rather than guessing from an address alone.

No listing here carries a Sponsored tag, since paid placement isn't running in this category yet, so the order on the page reflects the raw data, not a promoted spot. If you run one of these Phoenix labs and your phone number or website field is blank, you can claim the listing and add it, which spares the next person a wasted trip. With 124 options spread across dozens of ZIPs, a few minutes checking details first beats showing up at a lab that can't run the test you need.
