1 cm per month<\/strong>), it incorporates small amounts of substances present in the bloodstream. <\/p>This allows analysis of toxic exposure over a period of up to 6 months<\/strong>, depending on the length of the sample.<\/p>The analysis is designed to detect habitual consumption or repeated exposure, not isolated instances.<\/p>
When a person is continuously exposed to a substance, small amounts accumulate in the hair or body hair and can be detected in the laboratory.<\/p>
However, in the case of isolated or single exposure<\/strong>, the amount that reaches the hair is usually very low and the body eliminates it before it can be fixed, so it normally does not leave a detectable trace<\/strong>.<\/p>What substances can be analyzed?<\/h3>
In our laboratory we analyze a wide variety of substances, including:<\/p>
- Metales pesados (plomo, mercurio, ars\u00e9nico, cadmio, etc.)<\/li>
- Sustancias medicamentosas<\/li>
- Drogas de consumo habitual<\/li><\/ul>
If you wish to analyze a specific substance and are not sure if it is included, you may contact us and we will inform you without obligation<\/strong>.<\/p>The sample must be obtained from the nape area<\/h3>
In addition to hair, it is also possible to perform the analysis from body hair<\/strong> (chest, arms, legs, etc.).<\/p>Unlike hair, body hair does not grow continuously<\/strong>, but rather has growth and rest phases. This causes substances to accumulate for longer, offering a wider detection window<\/strong>. <\/p>For this reason, body hair analysis allows study of exposures of approximately 9 to 12 months, with the most common being a window close to 9 months<\/strong>.<\/p>
