Overview of the Drug of Abuse Profile - Blood Sample/ No Chain of Custody Test
The Drug of Abuse Profile - Blood Sample/ No Chain of Custody is a blood-based toxicology screen covering seven drug groups.
The laboratory profile screens for Amphetamines, Barbiturates, Tricyclic Antidepressants, Benzodiazepines, Cannabinoids, Opiates and Cocaine.
Because this test is specifically provided without chain of custody, it does not use the formal identity verification, witnessed collection, specimen-sealing and documented transfer procedures generally associated with forensic or evidential drug testing.
It should therefore not automatically be assumed to meet the requirements of a court, employer, regulator, immigration authority or another organisation requiring formal chain-of-custody testing.
The test is intended for private or clinical-style screening where a blood-based drug profile is required without the formal evidential collection pathway.
Prescribed medicines and other substances can be relevant to interpretation, so a complete medication history should be supplied.

Amphetamines

People undergoing clinical-style toxicology assessment - Results can provide laboratory information about the substances covered by the assay.

How to Prepare

Prescribed medicines may legitimately account for findings within some of the drug classes included.
Symptoms and Reasons to Consider the Drug of Abuse Profile - Blood Sample/ No Chain of Custody Test
This profile is usually requested because drug exposure needs to be assessed rather than because of one particular symptom.
A need for private toxicology screening - Blood testing can provide laboratory evidence relevant to recent exposure within the assay's detection capabilities.
Concern about possible drug exposure - A targeted toxicology screen may provide useful information.
Medication or substance history requires clarification - Declared prescriptions should be considered alongside the result.
A clinician has requested blood toxicology testing - The profile covers seven defined drug groups.
A urine sample is not the preferred specimen - This version specifically uses blood.
Formal evidential testing is not required - No-chain-of-custody testing is intended for non-forensic use.
If testing is required for court, employment, licensing or another formal purpose, confirm the requesting organisation's collection and chain-of-custody requirements before booking.
A no-chain-of-custody result should not be assumed to satisfy evidential standards.

When Will I Receive My Results?

Turnaround begins once the specimen is entered into laboratory processing.
Additional investigation or confirmation can occasionally affect final reporting time.
Understanding Your Results
A negative screen means the substances covered by the assay were not detected above the relevant laboratory threshold.
This does not prove that a substance has never been taken.
Detection depends on the drug, dose, metabolism, specimen timing and analytical method.
A positive or detected result means the assay has identified a substance or drug group within its testing pathway.
Prescribed medication must be considered before conclusions are drawn.
The absence of formal chain-of-custody procedures also means the result is not equivalent to a forensic evidential test.
