The Quest Labs at 416 W. Las Tunas Drive in San Gabriel is an efficient, well-run lab. They have a conscientious staff who's pleasant, friendly, and GENTLE -- something patients don't always get in health care! Their waiting room is small, and sometimes it gets a little crowded, but it never stays that way for too long. This Quest Labs locations moves people through quickly but never forgets that they're PEOPLE. A+, all around!
