Frequently Asked Questions

 F.A.Q.s

drug-test  How do I know which is the correct drug test for me to do?


A simple urine test without a Chain of Custody is the routine and most cost-effective test to do. In certain cases, companies request a urine drug test with a Chain of Custody as part of their pre-employment procedure; e.g. Transport for London (TFL), or for legal reasons. This will be written on their letter to you. 


 
chain-of-custody  What does “Chain of Custody” mean?

The chain of custody is the chronological documentation or paper trail, showing the collection, transfer, receipt, analysis, storage, and disposal of the test sample. This is to make sure that any results that are reported definitely belong to a particular person. You will need to bring a photo ID with you like a passport or driving license when attending for this type of test.

 

    appointment-drug-alcohol-test  Do I need to make an appointment for the test?

    An appointment is required only for the urine drug test with a Chain of Custody. All other tests need no appointment and clients can attend Patient Reception at The Doctors Laboratory between 7am-7pm on weekdays and 9am-5pm on Saturdays.

     

    location-where-drug-alcohol-test  Where do I go to do the test?

    Once you have ordered the test, you need to go to Patient Reception at The Doctors Laboratory at: 76 Wimpole Street, London, W1G 9RT.
