Title: Oral Fluid Collection/Screening


1
  • Oral Fluid Collection/Screening
  • Training for Parents

2
Summary
  • The utility of saliva as a biological specimen
    for the detection of recent drug use has been
    supported by a number of studies. Correlation of
    drug in saliva and blood has been reported.
  • Unlike urine drug tests, saliva drug testing
    detects active drugs present at low
    concentrations (recent drug use, typically within
    hours).

3
Introduction
  • New OnSite OraLab 4 detects "under the
    influence" drug use for four drugs even before
    they're metabolized. And, its detection level for
    parent THC is lower and the most accurate in the
    industry.
  • With less than half the steps required by other
    oral fluid tests, OraLab's no mess design is
    truly simple and easy to administer.

4
Introduction
  • Its testing process is 100 observable and
    eliminates the need for special facilities, which
    makes specimen tampering less likely.
  • A unique, patent-pending expresser and single
    tube design allows you to collect and store
    sufficient saliva (can be measured and observed
    in the tube) for both immediate and confirmation
    testing.

5
Product Features
6
Intended Use
  • On-Site OraLab 4 detects drugs of abuse in
    saliva and provides for the collection,
    screening, transport, and storage of saliva
    specimens.
  • OraLab 4 is intended for forensic use in
    simultaneous, qualitative detection of multiple
    drugs and metabolites in saliva.

7
Intended Use
  • OraLab 4 provides only preliminary analytical
    test results. It is NOT an evidentiary test.
  • An alternate, more specific chemical method must
    be used to obtain confirmed analytical results -
    GC/MS testing via the Councils contracted
    outside laboratory.

8
OraLab Cutoff Concentrations
Drug ng/mL
  • COC (Cocaine) 20
  • OPI (Opiate) 40
  • MET (d-Methamphetamine) 50
  • THC (Delta 9 - Tetrahydrocannabinol) 50

9
Storage Stability
  • Store OraLab 4 tests at room temperature, 59
    86 F, in the original foil pouch.
  • If the foil pouch containing the OraLab 4
    profile card is damaged (e.g., a hole or tear),
    do NOT use that profile card.
  • Do NOT use OraLab 4 profile card more than 1
    year after the expiration date on the foil pouch.
    (See attached Varian letter).

10
Specimen Collection Handling
  • Specimens containing human-sourced materials
    should be handled as if potentially infectious.
  • Always wear disposable gloves and/or other
    appropriate personal protective equipment when
    collecting/handling any oral fluid specimens.
  • On-Site OraLab testing kits and collection
    components may be disposed of in any standard
    trash receptacle.

11
Subject Preparation
  • Prior to collection, instruct the donor to drink
    four ounces (4 oz.) of water, and to place
    nothing else in the mouth (food, drink, etc.) for
    10 minutes.

12
Subject Preparation
  • Instruct the donor to draw a pool of oral fluid
    into the mouth with a puckering action for a
    few moments before collection.

13
Instructions for Use
  • Step 1
  • Have donor keep foam collector in the mouth until
    thoroughly soaked (up to 3 minutes).

The donor should not chew or suck on foam.
14
Instructions for Use
  • Step 2
  • The administrator should place the collector
    foam-first into the expresser in the tube.

15
Instructions for Use
  • Step 3
  • Slowly push the collector down into the
    expresser.
  • You will feel some resistance about 2/3 the way
    down push past this to reach the bottom of the
    expresser (you will hear a popping sound).

16
Instructions for Use
  • Step 3
  • The oral fluid will flow into the tube. To
    express the maximum amount of sample, lift up
    slightly and push downward a second time.

Note It is important that a minimum of 1 ml of
sample is collected.
17
Instructions for Use
  • Step 4
  • Lift the collector out of the tube at a straight
    upward angle.
  • The expresser will be removed with it.
  • Throw both pieces away.

18
Instructions for Use
  • Step 5
  • Open the foil pouch and remove testing card.

Note Do not place profile card in mouth.
19
Instructions for Use
  • Step 6
  • Place testing card in tube as shown, arrow
    down.
  • Allow testing card to drop to the bottom of the
    tube.
  • Wait 10 minutes and interpret results.

Note Do not read results after 15 minutes.
20
Interpret Test Validity
  • A valid test is indicated by a band in the area
    of the card next to TV.

Profile card shown is for OralLab 6 product.
21
Interpret Test Validity
  • Since a valid test may give a faint or incomplete
    band, any Test Valid band confirms that the test
    is valid.
  • Due to the high viscosity and variability of some
    saliva samples, test results may require up to 15
    minutes to form.

Profile card shown is for OralLab 6 product.
22
Interpret Test Validity
  • An invalid test is indicated by the absence of a
    distinct band in the Test Valid area or by a
    reddish reagent background on the strip which
    obscures the presence of bands 15 minutes after
    the test is initiated.

23
Interpret Test Results
  • Immediately interpret test results as either
    negative or preliminary positive.

24
Interpret Test Results
  • Negative Result
  • A negative result for a given drug (i.e., drug
    absent or below the cutoff) is the PRESENCE of a
    band in the area adjacent to the drug name.
  • The test result pictured here is negative for
    cocaine, opiate, amphetamine, PCP,
    methamphetamine, and THC (marijuana).

25
Interpret Test Results
  • The intensity of the bands in the Results area
    may vary.
  • A negative sample may give a faint or incomplete
    band.
  • ANY band in the Result area indicates a negative
    result.

26
Interpret Test Results
  • Positive Result
  • A preliminary positive result for a given drug
    (i.e., drug present above the cutoff, suggesting
    current or recent drug use) is the ABSENCE of a
    band in the test result area adjacent to the drug
    name. The adjacent area appears off-white.
  • The result shown here is preliminarily positive
    for Cocaine.

27
Interpret Test Results
  • If all drug results are negative, or if no
    confirmation tests are required, properly discard
    the test card and tube.
  • When confirmation of a preliminary positive
    screen result is required, contact the Council on
    Alcohol and Drugs at (404) 223-2486 for
    instructions on how to obtain confirmation.

28
Confirmation Testing
  • Step 7
  • To send for confirmation, tightly seal the tube
    with the cap.
  • Contact the Council on Alcohol and Drugs for
    shipping instructions.
  • Ship box according to local, state, or federal
    regulations as instructed.

29
Collection/Testing Problem
  • If test did not run, or if invalid test results
    are obtained, contact the Council on Alcohol and
    Drugs at (404) 223-2486 after discarding the
    invalid test.
