It was not only a complete panel of blood work but also comprehensive notes from the clinician explaining each result. Very helpful.

Amber R.
Making an appointment online was very easy and with several locations and times available it was also very convenient. The number of tests included is a fantastic value. The explanation about each test and results was easy to understand.

It was a very thorough test and I like the explainations on the portal, however I would like to speak to someone so I can review my results. I am not a physician so I need some guidance.

lung nodule found which was actually just an MRI artifact and the earliest appointment they can give me to discuss is over 2 months away. For an out of pocket thousands of dollars scan this is totally unacceptable. I won’t be using again

The results took a very long time to provide a PDF results file. I had a doctor's appointment to review the results, but three weeks later, there was no PDF, even though the results were in. I had to cut and paste. The comments provided were very generic; I did not learn anything new.

I felt like the write up of the clinicians summary and notes were very good. I felt like they really looked at my information and took into consideration my thalassemia diagnosis. I feel there are specific things I can act on prior to my 6 month recheck. Very happy with my information.
