Laboratory Chain of Custody Form The form(s) used by the testing laboratory to document the security of the specimen and all aliquots of the specimens during testing and storage by the laboratory. The form, which may account for an entire laboratory test batch, shall include the names and signatures of all individuals who accessed the specimens or aliquots and the date and purpose of the access.
If you are accused of taking drugs, then the chain of custody is essential in making sure your sample has been handled correctly, demand a full sequence of documents and signatures from every person who has handled your sample, where, when and why, from collector to main laboratory, from screening laboratory to confirmation laboratory, which should state the condition of the sample, the volume within, the reasons for access, these should be written and not just tick boxes
Medical Review Officer (MRO) A licensed physician responsible for receiving laboratory results generated by an agency's drug testing program who has knowledge of substance abuse disorders and has appropriate medical training to interpret and evaluate an individual's positive test result together with his or her medical history and any other relevant biomedical information.
When accused of testing positive for drug abuse, you can demand the appointment of an MRO, make sure it’s a face to face meeting with medical exam. Ask that the laboratory reports are checked for accuracy and most important demand a full written report identifying every aspect of the MROs investigation
Quality Control Sample A sample used to evaluate whether or not the analytical procedure is operating within predefined tolerance limits. Calibrators, controls, negative urine samples, and blind samples are collectively referred to as "quality control samples" and each as a "sample."
I asked for the full laboratory report complete with method statement, and calibration documents. You may wish to send this to an expert witness, however if you study the documents carefully you should be able to work out all the errors, these laboratory’s are shoddy because they are not subject to rigorous external scrutiny,
- check that the quality control samples are located each side of the threshold,
- the known quantity’s of the drug matches the result.
- And the one thing that surprises me the most. Is that they do not test against uncontaminated urine or saliva but use blank samples. Which in my opinion questions the validity of the entire testing process?
