Hair Drug Test Information - A Few Things You Might Not Have Known
Hair drug testing is a growing but still somewhat unfamiliar drug testing process. People have questions all the time about it, so we decided to create a guide to the most important aspects of this home drug test process.
First of all, you are going to need a pretty specific amount of hair. At least 90 to 120 strands should be collected for submission, and if the hair is short or fine, collect a bit more.
Secondly, where you collect the hair is important. You must collect it from the scalp - you cannot just snip the ends off the hair. Although it takes some time to reach this point, drugs become harder to detect as the hair grows out and grows older. And it is also important to give the hair drug test laboratory a consistent starting point to work with. That point is a week before the hair was cut - it takes about a week for hair with or without drugs to grow out long enough to be cut and then analyzed.
The third thing to be aware of with this home drug test is that each half inch of hair that you provide represents about a month. Ideally, you want to provide an inch and a half of hair - that will give you a 90 day drug history. With a consumer test kit, 90 days is the maximum period of analysis for head hair (we will get into body hair later). You can submit hair a foot in length but only the inch and a half closest to the scalp will be analyzed. Do not, however, shorten the hair from the other end for that reason. Your hair drug test will specifically tell you how to collect the hair.google_ad_channel = "7940249670, " + AB_cat_channel + AB_unit_channel; google_language = "en"; google_ad_region = 'test';
