The Chromium and Cobalt Test is a lab blood test that measures the amount of chromium and cobalt in your body. Many doctors also call it a whole blood metal ion test, WB MoM test, or metal on metal ion test. It is often used to check people with metal on metal hip implants or possible metal exposure. You can book this test at participating labs through LabFinder and pick a time that works for you.
A whole blood chromium level and whole blood cobalt level check how much of these metals are in your bloodstream. This WB MoM test can help your doctor see if metal ions from an implant or another source are building up in your body. It does not diagnose a cause by itself, but it provides important numbers to guide care.
Common reasons: checking people with a metal on metal hip replacement, following up on hip pain or swelling after joint surgery, monitoring known metal exposure at work, and rechecking levels after a past high result. Your doctor may also order it if you have symptoms that could be related to metal levels, such as unusual fatigue or nerve tingling.
Plan about 15 to 30 minutes at the lab. You will check in, show your ID and the order, and sit in a chair. The technologist cleans your arm, places a small needle in a vein, and fills special trace metal tubes. The draw takes less than a minute. A bandage goes on and you can usually leave right away while your sample goes to the lab.
Yes, this is a quick, routine blood draw and is considered very safe. You might feel a quick pinch, notice a small bruise, or feel a little lightheaded for a moment afterward, but those effects usually fade quickly. Be sure to tell the staff if you take blood thinners, have a bleeding disorder, or if you have fainted during blood draws before. They will take extra care to keep you comfortable. Taking mineral supplements with chromium or cobalt right before testing can affect results, so follow any instructions from your doctor or the lab.
Follow your doctor’s steps: Some centers ask you to avoid vitamin or mineral supplements that contain chromium or cobalt for a short time before the draw. Ask about fasting: Most people do not need to fast, but check with the lab. Share implants and work: Tell the team about any hip or other metal implant and any workplace metal exposure. Review medicines: Bring a list of all medicines and supplements. Stay hydrated: Drinking water can make the blood draw easier.
This test may help evaluate problems after a metal on metal hip implant, possible metal exposure from work, ongoing joint pain or swelling after surgery, unexplained fatigue or numbness, and possible kidney or thyroid changes linked to metal levels. Results must be read in context. Your doctor will review your numbers along with your history and symptoms before recommending next steps.
