Laboratory Corporation of America

San Antonio's laboratory testing listings spread across dozens of ZIP codes rather than clustering in one part of town. The 78229 area carries 8 entries, 78258 has 7, and 78216 and 78217 each show 5, with smaller counts trailing off through 78240, 78238, and 78249. Out of 113 total listings for this category, 112 include a phone number and 95 list a website, so most entries give you a way to make contact before you drive over.

None of these listings are marked as verified, and this page doesn't have a sponsored placement program running yet, so nothing you see here is a paid ranking. Sponsored will label any promoted entry once that option exists, keeping paid spots visibly separate from the rest. If you run a lab in San Antonio and notice your phone number or website link is missing or outdated, you can claim the listing and correct it yourself. Given the spread across ZIPs like 78229 and 78258, calling two or three that are near you is a reasonable way to start, rather than assuming the first result on the page is your closest option.
