John
As a retired pharma rep I know blind spots in "healthcare". I had an event 10 years ago while traveling. I ended up in a Chicago ER at night. The report showed my Triglyceride/HDL ratio at 8.43. I am lucky I survived. I showed this to many Drs. in my territory. No doctor at that time knew how dangerous that was. I appreciate what you do. My ratio is now under one.

Charlie W.
Beginning with the blood draw, with so many vials (14-16?), I had no residual effects. Results began to populate my chart within 2 days and continued until all were done. Very easy to read and understand the results with explanatory notes. The clinician's report was very instructive.
