How far does the testing for a hair follicle and nail drug test go back? I am getting conflicting answers on both tests. I have been told 90-120 days or longer for hair follicle depending on length of hair and up to 1 1/2-2 1/2 years for nail testing.

Varies: The hair testing numbers are about right, with hair growing about 1/2 inch per month, and the average length of hair tested being 1 1/2 inches, which is about 90 days. Nails give 4-6 months at usual lengths. If you never cut them, or have very very long nails, you could get 1-2 years, but that is not common. ...Read more

Shouldn't : As long as this medication is prescribed by your physician -- that is not a reason to exclude you from employment. Be honest with your potential employer and bring the prescription bottle to your drug test so they can verify it. These types of drug tests want to detect illicit drug use or abuse. Hope that helps! ...Read more

86 days clean. Will i pass hair follicle test? Also how long till you receive results?

Hard to say: Typically, a hair test goes back 90 days, but it depends on how fast your hair grows. They are looking at 1 1/2 inches of hair, closest to the scalp. Incidentally, you should not avoid it by shaving your head. They would just use some other hair. And if they do, it is pretty obvious that you are trying to hide something. ...Read more

How long does cocaine come out of a hair follicle and how far back do applicants for an rn  get tested ?

How far BACK?: Maybe I'm missing something but I can't for the life of me figure out what "how far back do applicants for an RN get tested?" means? Unless you're Marty McFly then, nobody can be tested for ANYTHING required by a job application process any further BACK than the 1st day an application for a job requiring drug screening is made. Otherwise, you'd be testing people just THINKING about a certain job? ...Read more
