She also gave me advice to be super well hydrated and drink electrolytes the day before the blood draw, not just the morning of, which might help others like me too.

Aside from the wrong address on Google, very pleased. Since my son was diagnosed we have been to…read moredozens of labs dozens of times each. Labcorp (we've used five locations) is consistently the worst, quest (we've used three locations) is better but not usually covered by our insurance, and CLS (we've used two locations) is the best. We have never had problems at CLS that are common for Labcorp. Labcorp screws up a lab at least once every other visit - granted my son gets a lot of labs, but they are terrible. CLS has yet to screw up any of his labs and we've been there consistently for a while now. They have been professional, prompt, and communicative. It's almost as good as Children's Hospital main campus (NOT Parker which is Labcorp quality) for a fraction of the cost. Hard to find. Google sent me to the Admin Office on Union. The lab is in the Anthony's complex but not on the side with parking. It is around the back of the building (enter off Alameda & Routt). I spent an hour trying to find the lab. The staff was very proficient once I did. I was surprised the admin staff said that people come to their office all the time, yet they don't correct their address on google.

I recently came in for a bone scan and was disappointed by the front-desk experience. When I…read moreapproached the desk, one receptionist put a cracker in her mouth and the other appeared reluctant to assist me. I stood waiting to be acknowledged. In a medical setting--where patients may already feel anxious--a simple, professional greeting matters. Completing the intake forms was also difficult due to loud conversations among staff, including a man who came from the back offices and chatted loudly with the receptionists, making it hard to concentrate. I was particularly frustrated by the medical history form, which required strictly yes-or-no answers for family history. As an adoptee, I do not have access to my biological family's medical history. There was no option to indicate "unknown," and I was told to mark "No," which is not accurate. "No" is not the same as "unknown," especially when that information becomes part of the medical record. I hope the office will consider improving front-desk professionalism and making their intake forms more inclusive of patients with unknown family histories. Small changes would make a meaningful difference.
