What Is an Arsenic, 24 Hours Urine Test?
The arsenic, 24 hours urine test measures the amount of arsenic passed in your urine over a full day. It is used to assess whether a person has been exposed to arsenic through contaminated water, food, or workplace environments. This test is also called the arsenic urine test or 24-hour urinary arsenic test. This test requires collecting all urine produced over a 24-hour period in a container provided by the laboratory.
What Does an Arsenic, 24 Hours Urine Test Measure?
The arsenic, 24 hours urine test measures the amount of arsenic excreted in urine over a full 24-hour period. Since urine is one of the main ways the body eliminates arsenic, this test helps assess recent or ongoing exposure more accurately than a single urine sample. The parameter measured is listed below:
| Parameter | What It Tells You |
|---|---|
| Toxic Arsenic | Measures the amount of organic and inorganic arsenic present in a 24-hour urine sample. It helps assess arsenic exposure and supports the detection and monitoring of arsenic toxicity or poisoning. |
Why Is an Arsenic, 24 Hours Urine Test Done?
Doctors may request this test when they suspect a patient has been exposed to arsenic or when monitoring a known case of arsenic-related illness.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request a arsenic, 24 hours urine test:
- Nausea, vomiting, or persistent diarrhoea
- Abdominal pain or cramps
- Headache or unexplained fever
- Low blood pressure (hypotension)
- Skin darkening (hyperpigmentation) or thickened skin patches (hyperkeratosis)
- Numbness or tingling in the hands and feet (peripheral neuropathy)
- Unexplained anaemia (low red blood cell count)
Conditions This Test Can Help Detect
The arsenic urine test can help identify a range of conditions linked to arsenic exposure. These include:
- Environmental or occupational arsenic exposure from water, food, or industrial settings
- Acute or chronic arsenic toxicity and poisoning
- Long-term health conditions associated with chronic arsenic ingestion, including certain cancers and cardiovascular disease
- Type 2 diabetes linked to prolonged arsenic exposure
Arsenic, 24 Hours Urine Test for Chronic Disease Monitoring
This test is also used to track the progress of chelation therapy, a medical treatment that helps remove heavy metals from the body. Regular monitoring through urine arsenic levels helps doctors assess how well the treatment is working. For people with occupational exposure, urinary arsenic above 35 µg/L may call for closer monitoring and early intervention.
How to Prepare and What to Expect
Collecting a 24-hour urine sample is straightforward when you follow the instructions carefully.
Do You Need to Fast?
No fasting is required for the 24-hour urinary arsenic test. You can eat and drink as normal on the day of collection. However, you must avoid fish and seafood for at least 5 days prior to the day of collection. It is recommended to avoid tea and coffee before and during the collection period, as they have diuretic effects that can increase urine output. Always follow the instructions given by your doctor or the diagnostic centre at the time of booking.
Practical Tips Before Your Test
Keep the following points in mind before you begin collection:
- Avoid all fish and seafood for 5 days before starting collection, as seafood can significantly raise total arsenic levels in urine
- Avoid coffee or tea before and during the collection period, as their diuretic effects can increase urine production
- Avoid gadolinium- or iodine-based contrast media used in imaging scans for at least 96 hours prior to collection, as these interfere with test accuracy
- Use only the plastic container provided by the laboratory; avoid any contact with metal during collection
- Do not use containers with mercury-containing preservatives or metal caps
- Inform your doctor about any medications or supplements you are currently taking
Step-by-Step Procedure
- On the morning of collection (for example, at 8 AM), empty your bladder completely and discard this first specimen.
- From this point, collect every drop of urine you pass into the provided container for the next 24 hours.
- Keep the container sealed and store it as instructed by the laboratory, typically in a cool or refrigerated place.
- At the end of 24 hours (for example, 8 AM the following morning), collect your final specimen and add it to the container.
- Seal the container tightly and hand the sample to the collection agent.
- Your sample is then dispatched to the laboratory for analysis.
Factors That Can Affect Accuracy
Several factors may influence the reliability of your result. These include:
- Recent fish and seafood consumption (within 5 days of collection) can raise total arsenic levels significantly
- Coffee or tea intake before and during the collection period may increase urine production due to their diuretic properties
- Recent exposure to imaging contrast agents containing gadolinium or iodine
- Incomplete urine collection (missing one or more samples during the 24-hour window)
- Use of metal containers or contamination during collection
- Highly diluted or very concentrated urine
Understanding Your Arsenic, 24 Hours Urine Test Results
Your results should always be reviewed with your doctor, who will consider your exposure history, symptoms, and overall health. The table below shows general reference ranges:
| Parameter | Normal Range |
|---|---|
| Toxic Arsenic | <35.00 μg/L |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain situations can affect how your results are interpreted:
- Eating fish and seafood in the 5 days before collection can raise total arsenic levels significantly. This dietary arsenic is non-toxic, but it may be misleading if the test does not separate arsenic types (speciation).
- Gadolinium and iodine from contrast media used in scans can interfere with the testing method (ICP-MS), leading to inaccurate readings. In such cases, it is recommended to wait for a minimum of 96 hours before collecting a specimen for testing.
- Chronic arsenic exposure may also cause changes in blood cell counts, including anaemia, low white blood cell counts, and reduced platelets.
How to Maintain Healthy Levels
These general steps can help reduce arsenic exposure:
- Have your drinking water tested for arsenic, particularly if you use a well or live in an area with known groundwater contamination.
- Consider using an arsenic-removal water filtration system if contamination is present in your local supply.
- Limit intake of high-arsenic foods such as certain rice products and mushrooms if you have reason to be concerned about exposure.

Frequently Asked Questions
A single urine sample can give variable readings depending on how dilute or concentrated it is at that moment. Collecting urine over a full 24 hours captures the total amount of arsenic your body excretes in a day, making it a more reliable measure of overall exposure.
Seafood contains naturally occurring organic arsenic, mainly arsenobetaine and arsenocholine, which are non-toxic. Eating fish and seafood prior to 5 days of the sample collection can raise your total arsenic reading significantly.
Total arsenic includes all forms of arsenic in the sample. Not all forms are harmful; for example, the arsenic in seafood is non-toxic. Toxic arsenic refers specifically to inorganic and methylated forms, which are the types linked to poisoning and long-term disease. If total arsenic is high, further speciation testing separates the harmful forms from the harmless ones.
The arsenic urine test is suitable for people with possible occupational exposure (such as those working in mining, smelting, or agriculture); individuals living in areas with arsenic-contaminated groundwater; anyone with unexplained symptoms of toxicity; and patients currently undergoing chelation therapy for arsenic poisoning.
The 24-hour urinary arsenic test is one of the most useful tests for confirming recent arsenic exposure. For very recent or acute poisoning, a blood arsenic test may also be ordered, though arsenic is only detectable in blood for around 6 hours to 2 days after exposure. Your doctor will decide which test is most appropriate based on your situation.
Yes. The laboratory provides a plastic collection container. You collect all urine passed over the 24-hour period at home, following the instructions provided. Once complete, you can return the container to a Lupin Diagnostics centre or arrange for a home pickup.
