FTS Investigation: Thorough investigation and comprehensive test profile.
Establishing key facts with our detailed client questionnaire
The 35 minute client interview established in summary:
- The client had previously used heroin but claimed to have stopped 4 months ago.
- Frequent and recent use of bleach and a permanent hair dye every 3 to 4 weeks with the last use 2 weeks prior to sampling. Hair straighteners were also used regularly.
- Client taking 40ml of Methadone daily and had been for 5 months, having previously been on 60ml daily.
The matched hair sample and also a urine sample were tested by FTS, who carried out a hair strand test and urine test for opiates and methadone to establish a 3 months history immediately prior to sampling.
Hair sample cut to 4cm and segmented into 4 x 1cm segments
FTS completed the testing and investigated all factors that could influence the outcome of the test results. The profile of significantly increasing methadone levels from hair section 4 to section 1 mirrored by the heroin, codeine and morphine levels, in context with the type of hair treatments, frequency and period of their use, in combination with the low wash to extract ratio and positive urine test enabled FTS to come to the following conclusion based on the balance of probabilities:
FTS laboratory results
FTS experts reveal a Positive result over the same period and concluded:
“These results are compatible with the client using heroin on multiple occasions throughout each approximate 4-week index period up to the point of sample collection. These results do not appear to be consistent with the clients’ declaration.”
When the appropriate test profile is used and results interpreted in context with key factors (in particular methadone levels, hair treatments and wash ratios), FTS come to a very different conclusion from other laboratories despite the analysis finding relatively the same levels in the hair, leading to a different decision. Cost should not compromise the thoroughness of the investigation and testing.
