Metal Ion Blood Testing & Metal on Metal Hips
Where Can I Get a Metal Ion Blood Test?
Doctors recommend getting regular blood tests to make sure your Metal on Metal hip replacement isn’t shedding microscopic particles into your body and bloodstream.
Some physicians may not suggest this type of bloodwork if you don’t have any symptoms. However, you can request a cobalt-chromium blood test without a doctor’s referral.
Cobalt and chromium blood levels can be measured at most medical labs. The labs listed provide cobalt and chromium blood tests for individuals with MoM implants, with or without a physician referral.
Why Should I Get Tested for Metal Ions?
Research consistently shows that metal-on-metal hip implants can release microscopic cobalt and chromium particles into the blood. These particles can cause various types of metal poisoning, including Metallosis, ALVAL, ARMD, and ALTR. All of these reactions can lead to severe health complications, such as heart failure, vision loss, hearing loss, and even death.
The FDA says metal ion testing is important for patients to find out if they’re reacting to a metal on metal hip replacement.
The FDA report only suggests patients who have symptoms get blood testing. But, many leading orthopedic surgeons recommend metal on metal hip patients get blood testing every three months for as long as they have a metal hip implant.
Complications from a Metal on Metal Hip Replacement?
mctlaw attorneys are highly experienced in representing clients in these types of cases. They filed the FIRST case in the US against a manufacturer of defective metal on metal hip replacements.
What amount of metal in my blood is considered “unsafe”?
The FDA previously maintained that a safe level of metal ions in your blood is below 7.0 parts per billion for patients with metal-on-metal hips.
However, those guidelines became less clear in 2018, when the FDA shared the results of their three-year post-market surveillance study of metal-on-metal hip implants.
The FDA report, which examined over 2,000 failed metal-on-metal implant cases, found “the standard blood level threshold measurement of 7.0 parts per billion (micrograms/liter) or higher for metal ions, is not optimal to determine if an implant is functioning safely.”
It showed that some patients with higher levels of metal blood ions had no complications, while other patients with much LOWER metal ion levels experienced serious reactions.
The FDA suggests metal ion blood testing for hip patients should be used in combination with other tests like CT scans, MARS MRIs and ultrasound.
Symptoms of a Defective Metal-on-Metal Hip
Patients with high blood levels may also experience other symptoms related to a defective metal on metal hip. These include:
– Tinnitus (constant ringing in ears)
– Pain or swelling in the hip joint
– Popping or clicking in the hip
– Apparent dislocation in the hip
– Heart failure or cardiomyopathy
– Pain when walking or bearing weight on the hip
