ZRTlabs provides same dry blood test I used last year except with shorter turn around time and 50 % cheaper. Even with small discount through canary club.
Tho I am forced to take another iodine stress test, but oh well... This test measures tt4, ft4, ft3, tsh, tpo, thyroglobulin, iodine, selenium, arsenic, bromine and creatine.
Same test through Nordic Labs, I used last year, costs 520 € with four days shipping (to Denmark, it is next to us, how can it take forever) + 21 days turn around time. Let alone the test kit comes from UK and that can take up to 8 days for some weird reason Finland is not that far away!!!
ZRT test I have to send to US, but as it is dry blood I can send it through normal post cheap and still quick-ish. Turn around time 3-5 days and it costs me 284$.
I am sorta happy and content, this test is reliable and easy to take. I had no idea newborns are tested with same method, dry blood. Pretty cool.
Unfortunately my ferritin remains untested as vit D, but at this point I am worried about thyroid levels. I hope this test helps me to get help, otherwise I am lost and no idea what to do.
