  • Select the drugs you want us to test for

    Cellmark has developed a panel system of hair drug testing to enable our customers to identify drug usage simply and easily.  

    Panel A includes the following common ‘drugs of abuse’: 

    • Amphetamine and methamphetamines - including MDMA (ecstasy)
    • Benzodiazepines - including diazepam, desmethyldiazepam (nordiazepam), temazepam, oxazepam and chlordiazepoxide
    • Cannabis
    • Cocaine - including markers to indicate the use of ‘crack’ cocaine and the concurrent use of cocaine and alcohol
    • Mephedrone
    • Methadone
    • Opiates – including morphine, codeine, dihydrocodeine, heroin and markers of heroin use
     

    Panel B. Our Supplementary Drugs of Abuse panel includes LSD, Ketamine and Phencyclidine (PCP).

    Individual drugs - cocaine and cannabis. 

    We offer a standalone test for cocaine – including markers to indicate the use of ‘crack’ cocaine and the concurrent use of cocaine and alcohol.  Whilst cannabis is the most commonly used drug of abuse it can be difficult to detect accurately. We have developed a very specific test for cannabis and its metabolites and this test can be selected in conjunction with either of our panels or as a stand alone test.

    Our service is designed to comply with the legal aid funding guidelines and is simple and economic.  We will give you an immediate quote over the telephone and if you want to go ahead we will take all your details there and then to avoid any delays.

  • Select the period of time you want to be analysed

    Head hair grows at an average rate of approximately one centimetre (cm) per month with a range of between approximately 0.7 and 1.5cm per month. At Cellmark we assume a growth rate of 1cm per month for our calculations when determining a history of use.

    You can ask us to analyse either a single section of head hair, or multiple sections. A single section provides an overview for that period of time and can be between 1 and 3cm (ie one, two or three month periods) to demonstrate patterns of drug use or abstinence over a period of time. The number of sections that can be tested will be dependent upon the length of sample available.

  • Hair strand sampling

    Hair strand sampling is best conducted by a person who has been specifically trained. Cellmark uses a dedicated sampling service whose samplers are skilled in taking all types of sample.

  • Alcohol consumption testing

    Cellmark offers an equally simple alcohol testing service to test for "chronic excessive alcohol consumption". Visit our dedicated alcohol testing page for full details.
