NHA LABORATORY
Human (Jockey) Testing

The Laboratory is well experienced in the analysis of human urine specimens from jockeys for prohibited substances.  These substances include recreational drugs which could impair the judgement of the jockey on the track and compromise safety.  The list includes substances such as an extensive list of amphetamines, cannabinoids (cannabis use), cocaine (and its metabolite benzoylecgonine), morphine, heroin, LSD, phencyclidine, barbiturates, benzodiazepines and diuretics.

Human urine screening for recreational and other drugs as a contract service

The screening can be conducted by either single use strip test kits or by extraction and mass spectrometry.  The strip tests (immuno/antibody based drug recognition) is known not to be 100% reliable in indicating drug presence correctly and thus drug suspects always have to be followed up for validity of result.  This is conducted by LC/MS/MS MRM.  The sensitivity of this technique requires low urine specimen volumes while providing a very high certainty of drug presence.  The latter technique is important for the detection of drugs even many days after use.  Where a high screening sensitivity is required specimens are automatically analysed by LC/MS/MS MRM.  While immuno strip testing could be seen as a less costly solution to drug screening, high screening sensitivity requires LC/MS/MS MRM.  Commercial immuno strip tests are also not suited for many new and designer drugs which can often not be detected at all.  The highly abused amphetamine type drugs are an example.  These are added to the LC/MS/MS MRM screen as new compounds become known and available.

 

The above urine screening is ideal for workplace and school recreational drug monitoring in urine specimens.  On request additional drugs can be added to the list which is offered and the required screening sensitivity can be specified.  The attraction of this screen is that suspicious specimens can be analysed at a high specificity of identification and a formal report can be compiled as a scientific report.  Such a report can be identical to those used in horseracing for legal prosecution.  A system of secure specimen collection vessels and security/sealing can be offered as to assist with a secure chain of custody of specimens between the time of specimen taking and witnessing and subsequent analysis at the Laboratory.

 

The detection of narcotic and other prescription/controlled drugs abused by hospital staff, other medical workers and staff handling or transporting medication is also easily and very conveniently conducted by the described LC/MS/MS MRM screening technique.
