When you have logged in go to the Resources tab and click on Learning Centre. On the page that comes up is a heading saying FTDNA test process. Click that and it will tell you
After I return the kit, how long will results take?
As of December 28, 2016, there are no delays in normal turnaround times.
Most of our tests typically take six to eight weeks to complete from the time we receive your sample in our lab, except Family Finder, which is usually four to six weeks and Big Y, which usually takes eight to ten weeks. Note that pending dates are an estimate only and subject to lab volume and quality control.
After we notify you that we have received your kit, you may sign in to your myFTDNA account to check your expected results date. Please note this is only an estimate and not a guaranteed results day, as a number of factors may cause your sample to be completed sooner or to be delayed.
