COT Rapid Test Cassette (Hair) JusChek Drug of Abuse Rapid Test

Hair detection has unique advantages in the field of drug testing .Hair can provide long-term medication information that is not available in other biological samples such as blood and urine. Hair samples are relatively easy to take, easy to carry, and easy to store for long periods of time. The slow metabolism of drugs in hair can persist for a long time, and these factors provide better conditions for drug analysis.
Allow the test, specimen, buffer, and/or controls to reach room temperature (15-30°C) prior to testing.
1. Remove the test cassette from the sealed pouch and use it within one hour. Collect the hair specimen from hair length close to the skin and cut hair of not less than 1 cm in length and not less than 100 mg.
2. Add the buffer to the Specimen Collection Tube with Catalyst Powder and shake it evenly to prepare the lysate.
3. Add the hair sample to the prepared hair lysate, tighten the cap onto the specimen collection tube, then shake the tube vigorously to mix the specimen and the lysate. Leave the tube alone for 5 minutes
4. Place the test cassette on a clean and level surface. Open the cap of the specimen collection tube and transfer 3 full drops of specimen (Lysate) (approx. 120μL) to the specimen well (S) of the test cassette, and then start the timer. Avoid trapping air bubbles in the specimen well (S).
5. Wait for the colored line(s) to appear. Read results at 5 minutes. Do not interpret the result after 10 minutes.
