What Is a Chromium Blood Test?
The Chromium blood test measures the level of chromium in the blood. Chromium is a mineral that plays a role in how the body processes insulin, sugar, fat, and protein. Doctors may prescribe this test to check for chromium poisoning, deficiency, or to monitor patients with metal-on-metal hip implants. It is also known as the serum Chromium test or Cr blood test, and uses a small blood sample drawn from a vein.
What Does a Chromium Blood Test Measure?
The Chromium blood test analyses the concentration of chromium in your serum. Chromium exists in two main forms, each with a different effect on the body. Here is a summary of what the test looks at:
| Component | What It Tells You |
|---|---|
| Trivalent chromium (Cr III) | The natural form found in food and supplements; supports insulin function |
| Hexavalent chromium (Cr VI) | An industrial byproduct that is toxic and can harm multiple organs |
| Overall serum chromium level | Indicates recent exposure, deficiency, or implant-related metal release |
Why Is a Chromium Blood Test Done?
Doctors order the Chromium blood test for several reasons, including suspected exposure, deficiency, or routine monitoring in at-risk individuals.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to recommend a Chromium blood test:
- Difficulty controlling blood sugar (glucose intolerance)
- Unexplained weight loss
- Tingling or numbness in the hands or feet (peripheral neuropathy)
- Persistent fatigue
- Confusion or impaired coordination
- Elevated levels of fatty acids in the blood
- Skin reactions or nasal irritation in workers exposed to chromium
Conditions This Test Can Help Detect
A Chromium blood test can help identify the following conditions:
- Chromium poisoning or toxicity from industrial or environmental exposure
- Chromium deficiency in patients receiving all nutrition intravenously (TPN)
- Excessive wear or malfunction of metal-on-metal hip replacement implants
- Occupational exposure-related issues such as contact dermatitis, nasal ulceration, or lung damage
- Recent toxic chromium exposure, typically within the last 8 to 10 weeks
Chromium Blood Test for Chronic Disease Monitoring
The Chromium blood test is an important monitoring tool for patients with metal-on-metal hip implants. Leading orthopaedic specialists recommend testing chromium and cobalt levels every three months for as long as a metal-on-metal implant is in place. Regular monitoring helps detect early signs of implant wear before serious complications develop.
How to Prepare and What to Expect
Preparation for the Chromium blood test procedure is straightforward, but a few steps are important for accurate results.
Do You Need to Fast?
No fasting is required before this test. However, you must stop taking mineral supplements and multivitamins for at least three days before sample collection, as these can affect your results.
Practical Tips Before Your Test
Follow these steps to ensure a smooth and accurate test:
- Stop all mineral supplements, chromium supplements, and multivitamins at least 3 days before the test
- Bring a detailed clinical history including your symptoms, previous test results, and relevant medical records, as this is required for the test
- Tell your doctor about all current medications
- Inform your doctor if you have recently had an imaging scan using gadolinium or iodine-based contrast media, as these can interfere with results
- Wear a short-sleeved shirt or one with loose sleeves to allow easy access to your arm
- Stay well hydrated before your appointment
Step-by-Step Procedure
Here is what to expect during the Chromium blood test procedure:
- A trained phlebotomist cleans the skin on the inside of your elbow or the back of your hand
- An elastic band is tied around your upper arm to make the vein more visible
- A fine needle is gently inserted into the vein to draw approximately 3 ml of blood
- You may feel a brief sting when the needle goes in and mild throbbing afterwards. This is normal and passes quickly
- The blood is collected into a specialised gel tube to ensure the sample remains stable
- The sample is refrigerated and sent to the laboratory, where it is analysed using the ICP-MS/AES/OES method
Factors That Can Affect Accuracy
Several factors can affect the reliability of your results:
- Use of a non-certified collection tube can cause contamination and falsely elevated readings
- Recent intake of chromium supplements or multivitamins
- Gadolinium or iodine-based contrast media used during imaging (wait at least 96 hours before collecting the sample)
- Dehydration at the time of collection
- Chromium clears from the blood quickly, so results reflect only recent exposure
Understanding Your Chromium Blood Test Results
Your results should always be reviewed alongside your clinical history and discussed with your doctor. The table below shows general reference ranges for serum chromium.
| Parameter | Normal Range | Unit |
|---|---|---|
| Serum Chromium | Up to 1.4 | µg/L |
| Serum Chromium | Up to 26.92 | nmol/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 results are interpreted:
- In patients with metal-on-metal hip implants, serum chromium levels may be elevated even without symptoms. Your doctor will assess whether the level indicates normal implant function or excessive wear.
- Chromium clears from the blood rapidly, so elevated levels reflect recent rather than long-term exposure.
- Sample contamination during collection can produce falsely high readings. If this is suspected, a second sample collected in a certified metal-free tube may be needed.
How to Maintain Healthy Levels
These general tips can support healthy chromium balance:
- Include chromium-rich foods in your diet, such as broccoli, barley, oats, green beans, and lean meats.
- Reduce consumption of refined sugars and processed foods, which can deplete chromium stores over time.
- If you work in an industry with chromium exposure, follow all recommended workplace safety and protective equipment protocols.

Frequently Asked Questions
The Chromium blood test is used to detect chromium poisoning or deficiency and to monitor patients with metal-on-metal hip implants. It may also be ordered for workers in industries such as welding, electroplating, and leather tanning who have regular chromium exposure.
This test is recommended for workers exposed to industrial chromium, patients with metal-on-metal hip replacements, and those receiving long-term intravenous nutrition (TPN). Your doctor may also suggest it if you have symptoms such as unexplained weight loss, blood sugar problems, or nerve-related issues.
No fasting is required. However, you should stop taking mineral supplements, chromium supplements, and multivitamins at least three days before the test to avoid interference with your results.
Chromium toxicity usually results from exposure to hexavalent chromium in industrial settings and can affect the lungs, skin, kidneys, and liver. Chromium deficiency, on the other hand, has been documented mainly in patients on total parenteral nutrition without added chromium, and typically causes blood sugar problems and nerve-related symptoms.
Metal-on-metal hip implants can shed tiny metal particles into the bloodstream over time. Regular Chromium blood test monitoring helps detect whether an implant is wearing excessively or not functioning correctly, allowing your doctor to take action before serious complications develop.
The report is delivered within 11 days from the time of sample collection at Lupin Diagnostics. The test requires specialised analytical methods, which account for the longer turnaround time.
Yes. Chromium supplements and multivitamins taken close to the test can interfere with accurate measurement. Stop all such supplements at least three days before Chromium blood test sample collection to ensure your results reflect your true chromium levels.
