NARCOTEST® INSTRUCTIONS

DESCRIPTION OF THE TEST UNIT

Individual test units consist of a flexible plastic tube in which a crushable glass ampoule(s) has been sealed. Most ampoules contain 0.5 ml of reagent. Reagents #1, 2, 3, 6, & 26 each have one ampoule. Reagents #4, 5, 7, 8, 9, 13, 14, 23, 24, 25, & 27 have a second ampoule in the cap. Care should be exercised in removing and replacing the cap to make sure the ampoule is not broken.
Apply pressure at the liquid level (or at the mid-point of the cap) to break the ampoules.

TESTING AN UNKNOWN MATERIAL

Testing an unknown is simple. It is important to thoroughly read the following procedure to familiarize oneself with all steps and operations. The following protocol applies to all materials tested. Refer to the Individual Test Instructions section for greater detail.
The correct test unit is opened by carefully removing the cap and the proper amount of suspect material (see next section) is placed in the tube. Hold the tube at the top between the thumb and forefinger to prevent static electricity from dispersing the sample. The cap is then replaced and the material forced to the bottom of the tube by tapping the tube on a hard surface. Each ampoule is broken by exerting sufficient pressure at the liquid level.
Always break the bottom ampoule first. DO NOT try to crush the broken glass. All that is needed is to release the chemical reagent sealed within the ampoule. The reagents are mixed with the suspect material by flicking the side of the tube with the forefinger near the bottom after each ampoule is broken. The colors produced are compared with those on the proper chart immediately to no more than 60 seconds after breaking the final ampoule. The sample test unit is properly discarded after recording the color obtained from that particular test.
Note: INTENSE COLORS: May result from overloading or waiting too long to view the color, suggest repeating the test using less sample if required, or hold the tube almost horizontally to allow a thin layer of liquid to coat the wall of the tube. Light filtered through this thin layer will allow the color to be compared.
WEAK COLORS: This problem may occur with the hallucinogens or other weak samples. Repeat the test using two or three times the normal sample size.

QUANTITY OF SAMPLE NEEDED

Only a small quantity of suspect material is required to obtain a presumptive identification. A standard flat, wooden toothpick makes an inexpensive and easily obtained sampling device. Mark the broader end at a point 3/16 of an inch from the end. The suspect material can then be picked up to this point on the toothpick. This usually will provide between one (1) and three (3) milligrams for use as a sample. Fluffy drugs like cocaine HCl require a larger sample size. Familiarity with the testing procedure will eventually make it easier to judge the proper amount of sample needed. A pen knife or similar item may be used in place of the toothpick. Care should be taken to ensure that any measuring device is clean and free of contaminating material from previous tests.

PREPARATION OF SUSPECT MATERIAL

ALWAYS RETAIN SUFFICIENT SAMPLE OF SUSPECT MATERIAL FOR EVIDENTIAL ANALYSIS BY THE FORENSIC LABORATORY OR TOXICOLOGIST.

A great deal of effort has gone into the preparation of the charts and color comparisons; however, colors described or printed are, at best, relative. Responses will be affected by purity and/or size of the sample, lighting conditions, temperature, how well the sample has been mixed with the reagent and a number of other factors. Only if the FULL TESTING SEQUENCE is followed, and common sense applied to reading color responses, will the results be conclusive.

HOW TO USE THE SEQUENTIAL TEST CHARTS

DISPOSAL OF TEST UNITS

After color comparisons have been obtained and recorded, promptly dispose of the used test unit in a safe place. DO NOT STORE USED TEST UNITS! The contents of the used test may leak resulting in damage to clothing or bodily injury. If no safe disposal place is immediately available, place the used test units in one of the poly bags (part #7610) provided with the kit until such time as they can be safely discarded. DO NOT discard used #7603 units with used units of either #7607 or #7608.
