An antimony toxin test measures the amount of antimony (a heavy metal) in a biological sample—most commonly urine or blood—to quantify recent or ongoing exposure; hair or nail samples may be used to assess longer‑term exposure.

These results report your personal antimony level (typically in micrograms per liter or gram) to help assess exposure and guide follow‑up; they are intended only to show your personal levels and do not by themselves diagnose health effects or predict symptoms.

Antimony is most commonly tested in urine (either a spot urine or a 24‑hour collection) and sometimes in blood for suspected very recent/acute exposures; hair or nails may be used for longer‑term exposure assessment but are less common.

Urine collection: follow the lab’s kit instructions—use the provided trace‑metal‑free container, discard the first morning void and then collect all urine for the next 24 hours (include the final morning void), keep the collection refrigerated, and return it promptly. Blood collection: a trained phlebotomist draws a sample into a trace‑metal‑free tube to avoid contamination. No special fasting is usually required; avoid contamination from topical products or environmental sources and follow any additional lab instructions.

Antimony test results indicate whether you have been exposed to higher-than-expected amounts of antimony and suggest the timing of that exposure: blood levels primarily reflect recent/ongoing exposure (hours–days), urine is useful for recent to short-term exposure and for monitoring removal from exposure (days–weeks), and hair or nails can reflect longer-term past exposure (weeks–months). A result within the laboratory’s reference range generally means no significant recent exposure, while elevated levels suggest recent or ongoing exposure that may require investigation and action.

Results must be interpreted with your clinician using your symptoms and exposure history—high antimony can affect the lungs, skin, gastrointestinal tract, heart, and nervous system—and trigger steps such as identifying and stopping the exposure source, medical monitoring, supportive care, and in severe poisoning, specialist treatment (e.g., chelation) where appropriate. Keep in mind labs use different reference ranges and there are limitations (timing of sampling, lab variability, and possible environmental contamination), so borderline or unexpected results often prompt repeat testing and occupational or public‑health evaluation rather than immediate conclusions about long‑term health.

Accuracy depends on timing of sampling, specimen choice and handling, laboratory quality (accreditation and quality control), limits of detection, and prior treatments such as chelation. Contamination during collection or storage and biological variability can cause false positives or negatives, so results must be interpreted in the context of exposure history, clinical findings, and, when needed, repeat or speciation testing by a reference lab.

If you have no known exposure or symptoms, routine antimony testing is generally unnecessary. Test when there is a clear reason — work-related exposure, accidental or environmental contamination, or symptoms suggestive of antimony toxicity — rather than on a fixed schedule for the general population.

For people with occupational or ongoing exposure, employers/clinicians commonly obtain a baseline test and then periodic monitoring (often annually, more frequently if exposure is high or changing). After a suspected acute exposure test immediately and repeat as advised by your clinician until levels fall; after removing a chronic source, retest weeks to a few months later to confirm decline. If you’re being treated (for example, with chelation), monitoring will be more frequent (weekly to monthly) per your treating clinician’s plan — follow occupational health or your provider’s recommendations for exact timing.

Yes. Antimony concentrations in biological samples can change relatively quickly after a change in exposure — typically over hours to days — because antimony is absorbed, distributed, and eliminated by the body. The rate of change depends on the chemical form of antimony, the route and magnitude of exposure, and individual factors such as kidney function.

Because levels reflect recent exposure, a single test may not distinguish acute from chronic exposure; timed or serial urine/blood samples and clinical context are often needed for accurate interpretation, so results should be discussed with a clinician or toxicologist.

No, antimony toxin test results highlight patterns of imbalance or resilience—not medical diagnoses.

They should be interpreted alongside symptoms, medical history, and other lab or biomarker data by a qualified clinician.

If your antimony test is elevated, first eliminate or reduce exposure: identify and stop contact with the likely source (workplace smelting/metal processing, contaminated water or products), remove contaminated clothing, wash exposed skin, and switch to a safe water/food source if contamination is suspected. Notify your employer or local public-health/occupational-health authorities if the exposure is workplace-related.

Follow up with your healthcare provider or poison-control center for medical evaluation—clinicians will monitor kidney/liver function, repeat levels, and treat symptoms. In cases of significant poisoning, treatment in a medical setting (which may include supportive care and, only when clinically indicated, chelation administered by a physician) can be used; do not attempt chelation or other treatments on your own. Continue follow-up testing and use engineering controls/PPE or remediation measures to prevent re‑exposure until levels normalize.
