I have always gotten my blood work with quest and I kept seeing ads about a site called “Rhythm” it seemed weird because it drew the blood from a device you use at home and ship it out yourself. My concerns with it was if it gets enough blood to truly get an accurate reading for some of the things they test for. I paid about $50 for this test as I had a discount code. Let me know what you guys think and any questions. My test I get done from last cruise was relatively the same as this. I want to go get another test done asap and see how far off it really is!
