Instrument Upgrade Announcement

Effective June 29, 2020, the reference intervals and interpretive comments that accompany the HTMA reports have been updated.


Instrument Upgrade

We're excited to announce a Hair Tissue Mineral Analysis instrument upgrade at our laboratory, Trace Elements Inc. The upgrade includes two state-of-the-art Perkin Elmer Nexion 1000 ICP-MS systems. To comply with regulatory standards, extensive method validation studies were performed to ensure results obtained with the new instrumentation are accurate and comparable to those obtained with the previous ICP-MS systems. 

Verification

These validation studies included establishing new reference intervals.  As with the current reference intervals established in 2000, these new ranges reflect the average analyte concentration ± 2 standard deviations for a population of normal “healthy” individuals. For those of us less technical, the results are based on the Gaussian Distribution (Normal Distribution) often described as a bell-shaped curve. 95% of healthy individuals fall within 2 standard deviations of the middle of the curve and 68% fall within 1 standard deviation. (See image below) The reference population used for this measurement was taken from North America, Europe, South America, East Asia, Australia and New Zealand. All ages and both sexes were included.
