Situational diagnostic tests Flashcards
how can cocaine be detected
RCT- detected in sweat and saliva using a low cost chip and surface enhanced Raman spectroscopy
what forms the basis of legal action for driving under the limit testing
sobriety tests linked to quantifiable chemical tests (RCT)
what do sobriety tests cover
- verbal incoherency
- walk the line
- touch the nose
- stand still, stand on one leg
- response to posed questions or simple calculations
- breath test
- gaze and pupil dilation
what are the penalties for drug driving
- a professional FTP ban
- minimum 1 year driving ban
- unlimited fine
- up to 6 months in prison
- a criminal record
- prison sentence of up to 14 years for causing death by dangerous driving
what do police use to establish the presence of drugs
drug screening device
- these can test up to 6 drugs in a single test of a persons saliva
what are the exceptions to drug driving tests
- there are no longer a number of concerns about whether the limits accurately affect the different speeds at which the drug breaks down in the blood
- some prescribed drugs could give positive results for illicit drugs
- eg dexamphetamine or sativex
outline the diagnostic tests performed at the roadside
- salivaConfirm4- saliva test
- easy to read drug test kit that uses saliva for the sample - drugalysers- tests for cannabis, alcohol, heroin and cocaine
what diagnostic tests are performed back at the station
- 8 panel drug test with integrated cup- urine test
- multi drug test kit that gives a result in 10 minutes
describe how drug kits based on spectrometry work
- colour evolution based of chromatography or multiple redox reactions
- use of specific enzymes to promote a response- colour, loss of colour, luminescence
describe how drug kits based on electrochemical response work
based on redox reactions that may involve an enzyme liberating electrons and producing a measurable current
