Common uses of these biochemical markers are: 1. Biochemical markers are not adequate screening or assessment instruments alone, but rather are used to support a more comprehensive clinical assessment. This is not the case for most other substances of abuse.

Tests in all of these areas are reasonably well developed and validated for alcohol. This section focuses on biochemical laboratory tests that detect the presence or absence of alcohol or another substance of abuse, may be able to quantify the level of present use, or may be able to quantify cumulative use over the past few weeks.
