Chain of Custody Drug Tests

chain-of-custody-drug-test

   Why would I do a Chain of Custody drug test?

A Chain of Custody drug test is usually requested by employers (e.g. TfL) or by courts and can be used for legal purposes; e.g. family courts.

   What does “Chain of Custody” mean?

The Chain of Custody is the step by step documentation or paper trail, showing the collection, transfer, receipt, analysis, storage, and disposal of the test sample. Each person who handles the sample will note the time that they did so and sign for it. This ensures that any results definitely belong to a particular person and are not tampered with.

   How long does it take for the results?

For a Chain of Custody urine drug test, a negative result is reported within 2 working days. A sample which tests positive is then put through further specialised testing which will take an extra 5 working days.

A Chain of Custody hair drug test can take up to 21 days. Results are e-mailed to clients.

 

   What is a false positive result?

This is a test which comes up positive on the first test, but then specialised testing proves that it is actually negative and the first result was wrong; i.e. a false positive. This happens in less than 1% of tests.

   What is an invalid test?

This is a test where there is doubt that the sample is 100% urine because of tampering or because the client has drunk too much fluids before doing the test. This makes the urine too dilute and cannot give you an accurate result.

The test is therefore not valid and has to be repeated by paying for another test.
