Why choose TDDA’s nail drug and alcohol testing services?
As one of Australasia’s leading workplace substance testing providers, TDDA combines robust collection procedures, experienced collectors, and internationally recognised laboratory partners to deliver a professional nail testing service you can trust.
Nail testing provides an alternative when hair testing options are unavailable, unsuitable or undesirable and can provide valuable insight into historical drug use over an extended period. It is particularly useful in family court matters, rehabilitation programmes, workplace investigations, and situations where a longer pattern of drug use needs to be assessed.
What is a nail drug and/or alcohol test?
TDDA nail testing detects people who choose a lifestyle of drug and alcohol use as opposed to one off use. Since a bloodstream feeds nail growth, TDDA can report on the ingestion of drugs and alcohol by analysing a small amount of nail clippings.
