Before You Start

Rinse Hair thoroughly and dry it completely before collecting your sample. If you have recently treated your hair, do not complete the test. Hair that has been permed, dyed, bleached, or otherwise chemically treated is vulnerable to contamination and should not be used. For best results, wait at least one month following any of these procedures to allow new hair to grow out.

Let’s Get Started

  1. Complete the information on the barcode sticker by writing the patient’s name, date of birth, collection date, and time. Use blue or black ink from a ball-point pen. Do not use felt-tipped pens or dry-erase markers. If this information is missing, your sample will be rejected.
  2. Place the barcode sticker on the clear zip-lock bag. Remember: Your sample can’t be tested without patient information on the bag containing the sample.
  3. Set up the scale – Follow the instructions printed on the scale.
  4. For best results, we recommend that you use a clean, sharp stainless-steel scissors. Select 5–6 small places on the back of your head that you can easily reach with your scissors.
  5. Cut as close to the scalp as possible to make sure you are capturing the most recent hair growth. Save only 1 inch (2.5 cm) of the hair closest to the scalp, discard the rest. Place the hair that was closest to your scalp on the white circle on the scale.
  6. Continue to add hair until the scale tips down to touches the table. Place hair in the clear zip-lock bag.

Preparing the Package

  1. Seal the clear zip-lock bag.
  2. Ensure the barcode label on the kit bag has been completed.
  3. Place the zip-lock specimen bag in the supplied shipping envelope.

Locate the shipping instruction card for details on how to ship your specimen.
