Laboratory Testing

Philadelphia

87 businesses listed, showing 1–40. How we order them.

Philadelphia's laboratory testing list runs 87 listings deep, and most of them are easy to reach before you ever leave the house. Sixty-seven have a phone number on file and 75 list a website, so calling ahead or checking hours online works for the majority of names here. The listings cluster around zip codes like 19104, which carries 17 entries, along with smaller groups in 19107, 19114, 19136, and 19145. That spread means you can often find a lab close to your neighborhood rather than crossing the city.

None of these listings carry a Sponsored label right now, since paid placement for this category hasn't gone live in Philadelphia, so what you're browsing is a plain, unranked set of records rather than a curated shortlist. Call two or three that fit your zip and confirm they handle the specific test you need before you show up. If you run one of these labs and see your phone or website field sitting blank, you can claim the listing yourself and fill in the gap, which spares a patient from dialing a number that goes nowhere.
