San Antonio

31 businesses listed. How we order them.

San Antonio's laboratory listings cluster in a few zip codes. 78229 leads with 5 entries, 78251 follows with 5, and several other zips, including 78212, 78216, 78219, and 78258, each carry 2. If you're near one of the lighter zips, like 78201 or 78207 with a single listing, call ahead to confirm hours and services before you drive over. Out of 31 labs listed for this category, most already show a phone number or website, so start there and use the thinner zips as a cue to double-check details rather than assume coverage.

Paid placements are labeled Sponsored whenever a category turns that feature on, and laboratory listings in San Antonio don't have any active yet, so nothing you scroll past here is a paid spot. If you manage one of these labs and your entry is missing a phone number or a working website, you can claim it and update the record yourself. That step matters most in zips with only one listing, where a stale number or dead link leaves searchers with no backup option nearby.
