Can A Chin Hair Be Used As A Sample For Drug Test?
Question: I had a hair test today. the hair was from my chin hair and it was about a 1/4 of an inch long. can it be tested accurately.
Brief Answer:
Yes,it can be used but only to provide an insight on the last 15 days or so
Detailed Answer:
Hello sir and welcome.
Thank you for writing to us.
I have gone through your query with diligence and would like you to know that I am here to help. The usual length of hair collected for a drug test (if that is the purpose of the sample provided by you) is about 1.5 inches long.
The hair sample should be cut from as close to the skin as possible (as that is the most recent part), and so the part closest to the skin is the part that is going to be tested.
0.5 inches represents 30 days, and so the usual size of the hair sample taken is about 1.5 inches to test for the last 90 days (3 months approximately). The sample collected in your case would only provide most recent information (approximately the last 15 days or so). But yes, it can be used for the test, just that the information provided will be only for the last 15 days or so, not more.
I hope I have explained things in a manner best understood by you. Please do not hesitate to write back to me for any further clarifications, I am always here to help.
Best wishes.
