| Accuracy:
The ability of a test device to produce a reading that matches the known
value for the sample. |
|
| Amnestic:
An agent used for the treatment of impaired memory function. |
|
| Analgesic:
An agent that relieves pain selectively without affecting consciousness
or sensory perception. |
|
| Anesthetic
(General): An agent that produces unconsciousness as well as
diminishing or eliminating the sensation of pain. |
|
| Anesthetic
(Local): An agent that diminishes or eliminates the sensation
of pain on or in the specific region of the body where it is applied. |
|
| Anorexic:
An agent that diminishes the appetite for food. |
|
| Anticonvulsant:
An agent used to control convulsions and seizures, primarily in the
treatment of epilepsy. |
|
| Antiemetic:
An agent that relieves vomiting. |
|
| Antihyperbilirubinemic:
An agent used for the treatment of antihyperbilirubinemia (jaundice) - a
common disorder in newborns wherein the chemical "bilirubin"
accumulates in the infants blood and causes a yellow hue. |
|
| Antitussive:
An agent that suppresses coughing. |
|
| Anxiolytic:
A mild sedative used for relief of anxiety. |
|
| Cannabinoid:
Any of the active principles of Cannabis Sativa (marijuana), including,
but not limited to, THC. |
|
| Central
Nervous System (CNS): Body system comprised of the brain and
spinal cord. |
|
| Central
Nervous System (CNS) Depressant: An agent that diminishes
brain and/or spinal cord function or activity. |
|
| Central
Nervous System (CNS) Stimulant: An agent that amplifies brain
and/or spinal cord function or activity. |
|
| Cross-reactivity:
The degree in which substances other than the target compound are shown
to generate positive test results. |
|
| Cutoff
Concentration: The specific concentration of drug or drug
metabolite in the sample that is chosen as a limit to distinguish a
positive from a negative test result. Samples with concentrations above
the cutoff level are considered positive and results below are
considered negative. |
|
| Depressant:
An agent that diminishes a body function or activity. |
|
| False
Negative Test Result: A test result which states that no drug
is present when, in fact, a tested drug or metabolite is present in an
amount greater the cutoff concentration. |
|
| False
Positive Test Result: A test result which states that a drug
or metabolite is present when, in fact, the drug or metabolite is not
present or is present in an amount less than the cutoff concentration. |
|
| Hallucinogen:
An agent that distorts sensory perceptions, sometimes resulting in
sensory illusions which may be mild or extreme. |
|
| Hypnotic:
An agent that induces sleep. |
|
| Interference:
The effect that a compound (or group of compounds) has on the accuracy
of test measurement. |
|
| Metabolite:
A modified form or byproduct of a drug produced by the bodys metabolic
process. |
|
| Narcotic
(Narcotic-Analgesic): An agent that relieves pain through
depression of the central nervous system. |
|
| Negative
Test Result: A test result which states that no drug or
metabolite is present or no drug or metabolite is present in an amount
greater the cutoff concentration. |
|
| Positive
Test Result: A test result which states that a drug or
metabolite is present. |
|
| Precision:
The ability of a test device to produce the same value during repeated
measurements. |
|
| Quantitative
Test Result: A test result expressed in numerical terms in
order to determine the specific quantity of drug or drug metabolite
present in the sample. |
|
| Qualitative
Test Result: A test result expressed in non-numerical terms in
order to determine the presence or absence of drug or drug metabolite in
the sample. |
|
| Reproducibility:
The ability of a test device to produce the same value during repeated
measurements in various laboratories which are participating in a
collaborative study. |
|
| Sedative:
An agent that calms nervousness, irritability, and excitement. In
general, sedatives depress the central nervous system and tend to cause
sluggishness and reduced mental activity. |
|
| Sedative-Hypnotic:
An agent that calms nervousness, irritability, and excitement and/or
induces sleep. In general, sedative-hypnotics depress the central
nervous system and tend to cause sluggishness and reduced mental
activity. |
|
| Sensitivity:
For quantitative test devices: The smallest concentration of a drug or
drug metabolite that produces a response distinguishable from the
background or blank value. For qualitative test devices: The minimum
concentration of a drug or drug metabolite that is capable of generating
a positive test result. In qualitative test devices, this amount is
generally the same as the cutoff concentration. |
|
| Specificity:
The ability of a test device to determine exclusively the drug and/or
drug metabolites that are claimed to be detected without cross-reacting
with other related substances that are not intended to be detected. |
|
| Stimulant:
An agent that amplifies a body function or activity. |
|
| Target
Drug/Metabolite: The drug or metabolite that the test device
is designed to detect. |
|
| Tranquilizer:
An agent used for relief of anxiety. |
