Everybody is super stressed and grumpy because lots of patients are fasting but just drink your water, bring a book, and chill if you can. I have a really hard time getting my blood drawn. The nurse was really great though. She got me a room where I could lay down, talked to me, and gave me a breathing exercise to do. It took a try on both arms to get a good site but they got it. 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.

So, don't waste your time without an appointment, unless you pack a lunch and are prepared to make yourself comfortable for the long haul (I'm not sure how long I would have waited - I finally left after 45 minutes). Also, the waiting area (never got back behind the "magic door") is really gross. Completely run down, dirty and it looked like it had been that exact way since the Cold War. (granted, it's on the old Lutheran site, so I guess I shouldn't be surprised)

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.
