I had a very positive experience with SiPhox. The blood collection process was straightforward and easy to complete at home. Through SiPhox testing, I learned that my thyroid was not functioning properly. This was the first time I had ever been tested for thyroid antibodies. Their support team proactively reached out to flag the results, which allowed me to follow up promptly with an endocrinologist and get the care I needed. I now monitor my thyroid every three months. Thank you, SiPhox, for helping me stay on top of my health.

Lots of kinks to iron out....
Pretty much nothing about this process went smoothly. It's a great idea, and the results seem to be solid, however the logistics suck.
I've used other at home bloodtests previously and this is the first one I've had any issues with.
Upon opening and preparing to take the text the kit code didn't work. The app didn't work either and I had to submit a ticket to get it resolved, delaying the test for almost a week. Upon taking the tests i provided blood levels well over the marked lines on the collectors in the hope you'd have enough. After shipping, there were multiple weeks of delays in processing. In processing i was informed the samples didn't provide enough blood, which simply isn't true.I provided more than you requested so if there isn't enough, that's on you. There is apparently yet another kit being shipped to me to provide more blood so you can complete the requested testing and provide the comprehensive results I requested and paid for from the beginning.
Overall, a pretty substandard experience all the way around.

Hello Josh! Thank you for taking the time to share your feedback. We’re sorry to hear that your experience did not meet expectations and that you encountered challenges throughout the process.
While we strive to make our at-home testing as seamless as possible, there are occasions where technical issues, increased sample volumes, or lab processing constraints can impact timelines and results. When this happens, we aim to be transparent and proactive in communicating updates or delays so customers are informed as soon as possible.
In cases where a sample cannot be fully analyzed, this is not always due to collection volume alone, and we make every effort to support members with replacement kits and additional guidance when needed. We also recognize that first-time collections can feel challenging, which is why we offer Live Help Calls to provide real-time support and improve the likelihood of a complete report.
We appreciate your feedback and are actively working to improve our logistics, communication, and overall experience.
Our support team has followed up directly, and we remain committed to delivering a more reliable and transparent experience moving forward.

She was very kind and very very patient
She was very kind and very, very patient with this senior lady and my husband, who is also helping on his end.. My blood did not want to flow out very easily so it took quite some time. We so appreciate all her help and guidance. Sincerely, Claudia Aratani.

Stefanija was an absolute joy to work with. She was incredibly knowledgeable about the process and walked me through it without any issues. The process took about fifteen minutes. So, there was a lot of time to talk about other things. She is a great conversationalist and a fascinating person.

Expensive
Expensive, took too long to get the results and even though the entire process was done under the “live instructions” with one of their coaches they said not enough blood was received to process all the test I had paid for.

Thank you for sharing your feedback, and we’re sorry to hear about your experience.
We’d like to clarify that when a sample can’t be fully analyzed, this isn’t always due to the amount of blood collected. Adequate volume can’t always be confirmed visually at the time of collection. During lab processing, samples are centrifuged to separate serum from other blood components, and in some cases, there may not be enough usable serum for all tests. This can occur due to natural biological variability or coagulation before processing, even when collection is completed with live guidance.
When this happens, we always offer a free replacement kit so members can retest at no additional cost. We encourage you to reach out to our support team so we can assist further and help make this right.
We appreciate your feedback and are continuously working to improve the overall experience.

Pointless if they dont test what you ordered
Pro was the easy and painless process of collecting. Problem is they only tested half of the labs I ordered due to saying they didnt have enough plasma. I followed the instructions to a t and filled the capsule to the 2nd line as directed. I have tried reaching out to see why this was an issue with no response back.

Hello Em, we appreciate you taking the time to leave your feedback, and we’re sorry that this experience didn’t meet your expectations.
We understand how disappointing it is when not all biomarkers can be reported, especially after carefully following the instructions. In cases like this, the issue isn’t always related to the amount of blood collected. During lab processing, samples are centrifuged to separate plasma, and sometimes there isn’t enough usable plasma to complete every test. This can happen due to natural biological variability or clotting before processing, even when the collection appears successful.
When this occurs, we always provide a free replacement kit so you can retest at no additional cost. We also strongly recommend joining a Live Help Call for collection, as real-time guidance often helps reduce the likelihood of incomplete results.
We regret that our response time was slower than usual due to a higher volume of inquiries, however we remain committed to supporting you and improving the experience.
