Terrible custom service be careful buying from this store. They forgot to stamp the return letter with the return form, when I realized unfortunately I had already done the blood test. I then contacted them to find a solution, they never responded, whether by email, on social networks they even saw my message but did not bother to respond and by phone unreachable neither. I had to manage to find the address of the laboratory and pay at my own expense the return of the sample because their customer service is non-existent. to flee there are better stores with better rates that offer good quality services

No match with blood test: Did a VitD test with cerascreen. So off!? Did a VitD test with cerascreen and blood test same day. Wanted to calibrate and see if I can trust cerascreen for periodic testing. Results: 63 ng/ml with blood test (Quest) and 116 ng (with warning of being too high by Cerascreen!!). Who to trust? Was really hoping for a match

5 stars Honestly, I don't know how all these people had problems with Cerascreen. I have been a loyal customer of theirs for a few years now. I have done several Vitamin D tests and never had any problems. The instructions come with the test, and the shipping is free (I live in Italy and their lab is in Germany). Once, they even offered to send me a replacement kit after I made a mistake taking the test! To me, this is amazing, considering the cost of the product. It means they really care about their clients. I will definitely keep on buying the Vitamin D test from CeraScreen!

Helpful Food Allergy Test I took the food allergy test and was pleasantly surprised by how straightforward the process was. Shipping was a day or two slower than anticipated, but I can't complain about that during a pandemic. The instructions were clear, getting the blood sample wasn't really painful at all, and the results were quite informative. I got confirmation of an allergy that I knew of, and found out about a couple of foods I might be sensitive to that might explain some stuff.

Funny how everyone is rating this test… Funny how everyone is rating this test on the basis of how quickly they got the results...when the test itself is hokum. Ah well, gullible and rich, the perfect combination for the creative entrepreneur.
