| 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 infant's 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 body's 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. |
