• There is no national consensus on when or how to perform pediatric drug testing.
• Each test has advantages and limitations.
• An understanding of these limitations is important in preventing misinterpretation.

• At risk of physical or emotional harm
• D/t drug use, possession, manufacturing, cultivation, or distribution
• Risk identification
• Injury surveillance
• Additional info/history
• Opportunity to improve life course trajectory
Test Characteristic Definition
Rapid Short turn-around time
Specific Limited cross-reaction with other drugs
Sensitive Detection at low concentrations of the drug in the specimen
Reliable One lab will derive the same result as another
Easy Technically uncomplicated
Inexpensive Cost:benefit ratio

• Layers of hair
• Types of hair• Vellus
• Intermediate
• Terminal
• Phases of growth• Anagen (1 cm/mo)
• Catagen
• Telogen
Curtis 2008, Farst 2011, Kintz 2017
• 1858 – Report published on arsenic in hair• 1977 – 1st modern use of hair drug testing• 1987 – NIDA considering hair as test
matrix for federal drug testing program• 1995 – Society of Hair Testing formed• 1998 – SAMHSA work group recommends
including hair as a test matrix• 2009 – FBI suspends hair testing in non-
criminal cases
SAMHSA 2013
• Workplace
• Criminal cases• Drug-facilitated crimes
• Detox clinics
• Sports
• Traffic court
• DEC and child custody• Neonates – hair sampled at or shortly after birth
• Passive exposure in the home
• Accidental ingestion or deliberate administration

• Window of detection = 90+ days
• Easy, non-invasive sample collection
• Decreased risk of adulteration
• Can be directly observed
• Easily stored/transported
Klein 2000, Levy 2014
• Sample size = 60-120 strands
• Location = vertex posterior scalp
• Orientation should be preserved (label which is closest to scalp)

1. Decontamination
2. Preparation
3. Incubation
4. Extraction
5. Analysis

• Finer, more porous hair
• Less available
• Anagen : catagen and growth rate vary
Kintz 2014, 2017, Wang 2015
• Higher respiratory rate• Increased risk of environmental
exposure• Developmental stage• Less data• Variable pharmacokinetics and
toxicity
Kintz 2014, 2015, 2017, Wang 2015
• Washing• Caveat: Incorporation from the environment
• Cut-offs• Caveat: not evidence-based
• “Environmental exposure will only generate a positive for the parent drug.”• Caveat: EXCEPT IF:
• The exposure was from the sweat/sebum of a drug user
• The drug contains a metabolite

• Systemic exposure• Better assessment
of health risk
• Environmental exposure• Testing is being
used to ID families in need of services
Kintz 2014, Farst 2011
• Variable hair growth rate and phase of growth
• Incorporation via sweat/sebum or external contamination
• Change in hair structure due to cosmetic treatment
• Incorporation via decontamination
Cuypers 2018, Kintz 2017
• Substance not on the test panel
• Substance at levels too low to be detected
• Missed window of detection
• Substance not incorporated into hair

• Contact with drug smoke or the actual drug
• Contact with sweat/sebum of a drug user
• Accidental/ intentional ingestion of the drug
• In utero exposure
• Intentional administration
• Close contact
• Smoke inhalation
Moosmann 2015, Kintz 2017
• Repeated exposure
• Contamination

Previous exposure
Provides no additional information Positive = child still being exposed OR still
positive from initial exposure
Negative = child not re-exposed OR child re-exposed but missed window of detection
Should not be relied on for safety decisions
SAMHSA 2010
• Confirmatory testing
• Lab standards
• Education
• No evidence of an impact on preventing future maltreatment

• Use of drug tests and the results should only be one component in the identification of child safety, risk, strengths, protective capacities, and needs of families.
• A positive drug test may indicate the need for a safety assessment but does not by itself indicate parental drug use, child maltreatment, or the need for out-of-home care.
• A negative drug test is not enough information to make a decision on reunification.
SAMHSA 2010, Farst 2011, Petska 2019
• Know your test (or a medical professional who does)!
• Test results must be interpreted carefully.
