It's not that pricey everywhere. My tests were around $325 if I remember right, but not over $400. Honestly, shop price before you decide who to give your business to, especially if you don't have insurance. Also, you will find a two tier system in the pricing. The first and higher tier is for those with insurance; the second is for those without insurance and can literally be half of what you would be charged with insurance. Also, find someone who will work with you when they write the script for the lab work. Sometimes the script gets written for a panel (standardized predetermined set of tests) sometimes it cheaper to just get the actual tests you need. In my instance getting the panel was cheaper than getting the individual tests.
This part is to, Happy Dog, I'm glad your doing so well. I'm so happy to have had a small part in your health. Best health to you always!
