Hair analysis may refer to the chemical analysis of a hair sample, but can also refer to microscopic analysis or comparison. Chemical hair analysis may be considered for retrospective purposes when blood and urine are no longer expected to contain a particular contaminant, typically three months or less. Its most widely accepted use is in the fields of forensic toxicology and, increasingly, environmental toxicology. Several alternative medicine fields also use various hair analyses for environmental toxicology, but these uses are controversial, evolving, and not standardized.

  • L'analyse des cheveux peut consister en une analyse microscopique ou en une analyse chimique. La première est utilisée dans les enquêtes criminelles pour la comparaison de différents échantillons, la seconde a un champ d'application plus large (examen de l'état de santé, détection de l'usage de médicaments ou de drogues, ou encore de produits toxiques présents dans l'environnement). Elle consiste en une analyse minérale des cheveux permettant de recenser les oligo-éléments ou de repérer les traces de certains produits (médicaments, drogues dont l'alcool, métaux lourds etc.). Ces élément peuvent avoir deux provenances : l'alimentation et le milieu ambiant (pollution de l'air, poussières). (fr)
  • Is féidir sampla gruaige a mhionanailísiú chun an leibhéal mianraí sa cholainn a thomhas le céimíocht cothaithe an duine a mheas, nó aon ábhar dochrach, cosúil le halúmanam nó luaidhe, a bhrath. Ní mór na ribí samplacha a phiocadh amach seachas iad a ghearradh, agus ag baic an mhuiníl mar a bhfásann an ghruaig níos tapa ná áit ar bith eile. Is fearr iontaofa na torthaí ar an tástáil seo nuair a dhéantar an anailís ar an ngruaig is gaire don chraiceann, de bhrí gur dócha go mbeidh gruaig eile truaillithe ag gallúnach, foltfholcadh, sprae, is ábhair gruagaireachta eile.

  • تتناول هذه المقالة الاستخدامات العلمية لتحليل الشعر. للممارسة الصحية الزائفة، انظر تحليل الشعر (الطب البديل). قد يشير تحليل الشعر إلى التحليل الكيميائي لعينة الشعر. ولكن قد يشير أيضًا إلى التحليل المجهري أو المقارنة. يمكن اعتبار تحليل الشعر الكيميائي لأغراض رجعية عندما لا يُتوقع احتواء الدم والبول على مادة ملوثة معينة. عادةً لمدة ثلاثة أشهر أو أقل. استخدامه الأكثر قبولًا على نطاق واسع هو في مجالات علم السموم الشرعي. وبشكل متزايد. علم السموم البيئية. تستخدم العديد من مجالات الطب البديل أيضًا تحليلات مختلفة للشعر لعلم السموم البيئية. ولكن هذه الاستخدامات مثيرة للجدل ومتطورة وغير موحدة.

  • Haaranalytik, auch Haaranalyse genannt, ist die Bezeichnung für eine chemische Analyse einer Haarprobe. Das Haar dient als leicht zugänglicher Biomonitor, in dem viele körperfremde Verbindungen in signifikant höherer Konzentration als in anderen Organen eingelagert werden. Der Begriff Haaranalytik selbst gibt keine Auskunft über das letztlich verwendete Analysenverfahren. (de)
