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 If you run a lab in San Antonio and notice your phone number or website link is missing or outdated, you can claim the listing and correct it yourself.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.
