Biomarker Summary

Toxic elements may be 200 to 300 times more concentrated in hair than in blood or urine, making hair useful for detecting recent exposure to arsenic, aluminum, cadmium, lead, antimony, and mercury. The CDC also recognizes hair mercury levels as a marker of maternal and infant exposure to neurotoxic methylmercury from fish.

WHY TEST

The Benefits of a Hair Toxic & Essential Elements Test

Hair analysis can provide a useful timeline of exposure to toxic elements and insight into essential nutrient patterns when reviewed with symptoms and other laboratory results.

01

Track Toxic Element Exposure

Hair may show recent exposure to elements such as arsenic, aluminum, cadmium, lead, antimony, and mercury.

02

Easy, Non-Invasive Sample

Scalp hair is simple to collect and does not require a blood draw or urine collection.

03

See a Timeline of Exposure

Because hair grows over time, it can provide a temporal record of element metabolism and exposure.

04

Assess Essential Nutrients

Review patterns involving magnesium, chromium, zinc, copper, and selenium—nutrients that support enzymes and normal vitamin function.

05

Support Earlier Insight

Results can add context that helps a practitioner investigate possible imbalances alongside symptoms and other lab values.

06

Guide Personalized Care

Clearer information about toxic elements and essential nutrients can support more focused conversations about next steps.

Trusted Testing Experience

Doctor's Data is a pioneer in elemental testing and has been validated as a supplier of trace element results for a European Commission reference material.

Why choose Doctor's Data Hair Test?

Doctor's Data has specialized in essential and toxic element testing since 1972. Hair analysis can add helpful context when reviewed alongside symptoms and other lab results.

A Record of Exposure

As hair grows, elements become incorporated into the hair shaft. Scalp hair is easy to collect and may provide a timeline of element metabolism and exposure.

Insight Into Essential Nutrients

Magnesium, chromium, zinc, copper, and selenium support enzymes and normal vitamin function. Hair results can help your practitioner assess these patterns with your symptoms and other labs.
