There is no other test to confirm B6 toxicity other than the blood test. Your doctor can order a blood test or you can order it yourself at Walk-In Labs. Walk-In Labs is an online lab that allows you to order most blood work WITHOUT a doctor’s order. You place the order and pay through Walk-In Labs. You go to Quest or LabCorp for the blood draw. The results are back in your Walk-In Lab portal the next day for most test. A B6 blood test takes three to four days.
