Regular medicine has said my slightly elevated cholesterol was ok for my age and fitness level; boy they were wrong! This test showed bad ApoA&B levels, causing me to get a calcium test and CT angiogram. Long story short, I was developing Coronary Artery Disease with no symptoms, all while running half marathons and looking “normal”. 2 stents later, I’m back running and have all my biomarkers in check. This service saved my life!

This service saved my life!

It is quite amazing you can get your blood test done from the comfort of your home! no need to make an appointment, drive, search for parking, etc. I also had a coaching session, which offered great recommendations on how to adjust my diet and supplements. The advice was far more detailed and personalized than anything I've gotten used to from primary care.

Great experience

I recently did comprehensive blood tests through Siphox. The testing was not hard to do. I am trying to optimize my metabolic, cardiovascular, hormonal, IR, organ function metrics. After receiving my results I was able to have a one on one consultation with Tasha, a health consultant, who answered all of my questions and followed up with an action plan based on my data and concerns. Everyone at Siphox has been helpful and very responsive.

Siphox is a valuable partner for those who want to optimize their health. 

This is such an amazing resource for anyone looking to dive deeper into their health. You can easily skip kits if you don't want to test monthly and the customer support has been extremely quick at responding and always helpful when I've reached out. This company cares deeply about customer satisfaction and their tests allowed me to advocate for myself, take charge of my health and get a diagnosis for a chronic illness that the conventional medical system was overlooking. I HIGHLY recommend.

This is such an amazing resource

I was extremely impressed with the entire experience. It was very informative to read all of the detailed information that was included with each of the lab values. And I was equally impressed with the suggestions for areas that I could undertake to improve my test results for the next draw. With all of the numerous blood draws I have had throughout my life I have never had such in-depth analysis of the results. Extremely beneficial in all regards. I will spread the word. Thank you!

Good data, easy process

I've run 2 sets of tests on SiPhox over the last year. The latest updates to the dashboard are a huge improvement and my coaching and  customer service experience has been excellent. I'm going to continue to run these in-between my doctor's visits as I feel like they give me  a VERY complete picture of my general health. I adjusted my FSA contributions to get this paid for on pre-tax dollars and while it might seem  a bit expensive, its a great value if you compare similar alá carte testing from Labcorp and they don't have all the extras SiPhox does. If  you're taking your health super-seriously then this is a great tool for you.

Best at-home blood test I've ever tried

I learned so much about my REAL health. After years of being physically active (competitive) and thinking I was taking care of my body, I figured it was time to learn more at a deeper level. After taking the first SiPhox test, I discovered that I had abnormally high levels of Ferritin (Iron) and this was the beginning of my journey of identifying and treating my hemochromatosis. I likely avoided serious health complications or death because of the service.
