Blood Drug Testing

How does the hair folice drug test work? Is there anyway to do a home version?

How does the hair follicle drug test work? Is there anyway to do a home version? Or to get a confidential result? I would like to check my child

1. Walgreens and Walmart sell the home version of a urine test but not a hair test, it will test for almost anything. Hair and cell testing (where they scrape the inside of your cheek) is expensive. Be careful not to jump to conclusions if your testing your child because some foods will make them test positive also.
2. For the hair tests, the residue of the drugs get deposited into your hair.
