Hair analysis
Hair Analysis
Hair analysis (pronunciation: /hɛər əˈnælɪsɪs/) is a technique used in forensic science, toxicology, and medical diagnostics to determine the levels of certain elements or drugs in a person's body.
Etymology
The term "hair analysis" is derived from the English words "hair", which refers to the thin threadlike strands growing from the skin of humans, and "analysis", which means a detailed examination of the elements or structure of something.
Procedure
Hair analysis typically involves the collection of a hair sample, usually from the head, which is then sent to a laboratory for testing. The hair is tested for the presence of specific substances, such as heavy metals, drugs, or nutritional deficiencies. The results can provide information about a person's health status, exposure to toxins, or drug use.
