Fastest Labs of NW Houston

Houston carries 190 laboratory testing listings, too many to scroll through one by one. Narrowing by zip code first speeds things up. Zip 77054 has 9 listings, the most of any area, with 77008 next at 6 and smaller clusters in 77074, 77014, 77065, 77081, and 77092. Start near your own zip and the list shrinks fast.

Most entries here include contact info: 188 show a phone number and 160 link to a website, so you can check services before calling. None of these Houston listings are marked verified. Paid placements carry a Sponsored label, and this category has no such tag right now, so what you're looking at is a plain, unranked list. If you run a lab and the number or site link is wrong, you can claim the listing and correct it, so the next Houston patient reaches you instead of a dead end. Pick two or three near you and call.
