What does the Thallium (Hair) test measure?

Q: What is Thallium (Hair)?

Thallium is highly toxic and accumulates rapidly in hair following exposure. Historical use in rodenticides and current industrial applications (electronics, optics) are primary sources. Thallium distributes widely and causes neurological and dermatological toxicity. Hair testing can detect exposure weeks after the event, as thallium incorporates during growth and remains stable.

Q: Why is Thallium (Hair) measured?

Thallium poisoning is rare but severe, presenting with painful peripheral neuropathy, alopecia (typically delayed 2–3 weeks), and gastrointestinal symptoms. Hair thallium is useful in forensic and retrospective exposure investigations. Any significant elevation demands urgent clinical correlation, exposure source investigation, and often chelation therapy. Environmental or occupational exposure is reportable.
