Titolo: info mineralogramma

Vorrei sapere se il mineralogramma può essere utile per rilevare la presenza 
di mercurio nell'organismo  e quali altri metalli permette di rilevare.
 
Grazie

Il mineralogramma ha lo stesso valore scientifico delle ali di 
pipistrello e degli occhi di lucertola ;-) 
 
Risparmia i tuoi soldi.

Vorrei sapere se il mineralogramma 
 
viene esaminato il capello , giusto ?

Abstract
 
Context  Hair mineral analysis is being used by health care
practitioners and promoted by laboratories as a clinical assessment
tool and to identify toxic exposures, 
*despite a 1985 study that found poor reliability for this test*.
 
Objective  To assess whether the reliability of data from commercial
laboratories advertising multimineral hair analyses for nutritional or
toxicity assessment has improved since the 1985 study.
 
Design, Setting, and Participants  A split hair sample taken from near
the scalp of a single healthy volunteer was submitted for analysis to
6 commercial US laboratories, which analyze 90% of samples submitted
for mineral analysis in the United States.
 
Main Outcome Measures  Agreement of test results for each analyte,
laboratory reference ranges, laboratory characteristics, and
interpretation of health implications.
 
Results  Laboratory differences in highest and lowest reported mineral
concentrations for the split sample exceeded 10-fold for 12 minerals,
and statistically significant (P<.05) extreme values were reported for
14 of the 31 minerals that were analyzed by 3 or more laboratories.
Variations also were found in laboratory sample preparation methods
and calibration standards. Laboratory designations of normal reference
ranges varied greatly, resulting in conflicting classifications (high,
normal, or low) of nearly all analyzed minerals. Laboratories also
provided conflicting dietary and nutritional supplement
recommendations based on their results.
 
******************************************************************************
Conclusions  Hair mineral analysis from these laboratories was
unreliable, and we recommend that health care practitioners refrain
from using such analyses to assess individual nutritional status or
suspected environmental exposures. Problems with the regulation and
certification of these laboratories also should be addressed.
