重金属头发测试

 这个测试是大平原用的Doctor Data 的，所以就是DDI的标准测试。

简介

金属(血液, 头发或尿) - 头发可以用为毒性金属的检测例如铅，铝，水银和镉。铅也许可以在路边的土里及比较旧的房子油漆里发现。异食癖或吃剥落油漆的孩子会有中毒水平的铅。镉使用于电池，围绕钢的轮胎和塑料里。食物用的透明塑料盖也许是镉的来源并且它也被发现在香烟里。汞被使用在电池，牙齿汞合金，真空泵，阀门和封印里。大数量汞来自火葬的逝者的牙齿充添物造成了周围的邻里的污染。砷的水平在海鲜里和饲料含有砷哺养动物的肉里是很高的。砷并且存在在木头防腐剂，杀真菌剂，除草药， 腐蚀抗化剂， 铅和铜合金里。有自闭症的孩子对去除毒性金属也许反应良好。有自闭症孩子有低水平的基本元素钙，钾，锌，和镁。治疗重金属暴露的通常涉及去除重金属来源并且/或者用螯合物治疗。

Heavy metals toxicity caused by increasing levels of pollution and use of chemicals in industry is a growing threat to our health and development of our children. High levels of toxic metals deposited in body tissues and subsequently in the brain, may cause significant developmental and neurological damage.

A Metals Hair Test is ideal for checking current exposure to toxic metals. With respect to its contained elements, hair is essentially an excretory tissue rather than a functional tissue. Hair provides important information which can assist the practitioner with an early diagnosis of physiological disorders associated with aberrations in essential and toxic element metabolism.

The U.S. Environmental Protection Agency stated in a recent report that “...if hair samples are properly collected and cleaned, and analyzed by the best analytic methods, using standards and blanks as required, in a clean and reliable laboratory by experienced personnel, the data are reliable.” (U.S.E.P.A. 600/4-79-049)

The CDC acknowledges that hair mercury levels provide a valuable maternal and infant marker for exposure to neurotoxic methylmercury from fish.

为什么选择头发检测？

Extensive research established that scalp hair element levels are related to human systemic levels. The strength of this relationship varies for specific elements, and many researchers consider hair as the tissue of choice for toxic and several nutrient elements. Unlike blood, hair element levels are not regulated by homeostatic mechanisms. Thus, deviations in hair element levels often appear prior to overt symptoms and can thereby be a valuable preliminary tool for predicting the development of physiological abnormalities.

Why hair?
With respect to its contained elements, hair is essentially an excretory tissue rather than a functional tissue. Hair element analysis provides important information which, in conjunction with symptoms and other laboratory values, can assist the physician with an early diagnosis of physiological disorders associated with aberrations in essential and toxic element metabolism.

As protein is synthesized in the hair follicle, elements are incorporated permanently into the hair with no further exchange with other tissues. Scalp hair is easy to sample, and because it grows an average of one to two cm per month, it contains a “temporal record” of element metabolism and exposure to toxic elements.

Nutrient elements including magnesium, chromium, zinc, copper and selenium are obligatory co-factors for hundreds of important enzymes and also are essential for the normal functions of vitamins. The levels of these elements in hair are correlated with levels in organs and other tissues.

Toxic elements may be 200-300 times more highly concentrated in hair than in blood or urine. Therefore, hair is the tissue of choice for detection of recent exposure to elements such as arsenic, aluminum, cadmium, lead, antimony, and mercury. The CDC acknowledges the value of hair mercury levels as a maternal and infant marker for exposure to neurotoxic methylmercury from fish.

Through recent vast improvements in technology, instrumentation, and application of scientific protocols, hair element analysis has become a valuable tool in providing dependable and useful data for physicians and their patients. The U.S. Environmental Protection agency stated in a recent report that “...if hair samples are properly collected and cleaned, and analyzed by the best analytic methods, using standards and blanks as required, in a clean and reliable laboratory by experienced personnel, the data are reliable.” (U.S.E.P.A. 600/4-79-049)

Hair, however, is vulnerable to external elemental contamination by means of certain shampoos, bleaches, dyes, and curing or straightening treatments. Therefore, the first step in the interpretation of a hair element report is to rule out sources of external contamination.

Hair element analysis is a valuable and inexpensive screen for physiological excess, deficiency or maldistribution of elements. It should not be considered a stand-alone diagnostic test for essential element function, and should be used in conjunction with patient symptoms and other laboratory tests.

检测的益处

	Determine if metal toxicity or mineral deficiency is contributing to your disorder.
	Monitor the effects of chelation (elimination of heavy metals from the body).
	Identify if supplementation of important minerals may bring about significant improvements
	Consultation about results is included with each test at The Great Plains Laboratory, Inc.
