Laboratory Testing

Dallas

100 businesses listed, showing 41–80. How we order them.

Dallas has 100 laboratory testing listings in this directory, but a name and address alone don't get a sample dropped off or a result back on time. Of those 100, 88 come with a phone number and 81 link out to a website, so most entries give you a real way to reach someone before you drive across town. Labs cluster around ZIP codes like 75243 and 75247, each with 8 listings, while spots such as 75203, 75206, 75231, 75237, 75238, and 75246 each carry 11. Call two or three near your ZIP to compare turnaround times and whether they handle your specific test before committing to one.

None of these listings are marked Sponsored, since paid placement hasn't rolled out for this Dallas category, so what you're scrolling through is directory order, not a curated pick. If a lab's phone number bounces or its website field sits empty, the people who run it can claim the listing and fill in the gaps themselves. That matters here more than in most categories, since a missing number turns a directory entry into a dead end for someone trying to schedule a test.
