There is not a medical provider or institution you can go to in order to have them tell you whether your symptoms are caused by Gadolinium retained from contrast MRIs, and there is no medical diagnosis of “Gadolinium Toxic”. An Unprovoked test will tell you the amount of Gadolinium that is normally being excreted. Being off on the start time or end time by one hour or so would not be a problem. I had a few others metals very slightly outside the reference ranges but nothing like gadolinium! My level was 2.980 – 156 times that.

Testing for Gadolinium in urine, especially provoked testing has some challenges. Change ), You are commenting using your Facebook account. I did see that Gena Norris, who suffered from GAD toxicity was able to chelate her levels down to zero in a little over 2 years with almost a complete resolution of symptoms. It may not be definitive, however. You should get either the Toxic Elements Clearance Profile or the Comprehensive Urine Element Panel. In our Study of Retained Gadolinium from Contrast MRIs report, we document urinary Gadolinium levels in 24-hour collections that show Gadolinium retention well beyond three days. The study involved 24 participants who were recruited between May 2016 and June 2017 and met the proposed GDD diagnostic criteria. The… For those who believe they are suffering from Gadolinium Toxicity, a 24-hour unprovoked urine test can provide some insight. Analysis of the these cases produced trend lines over time that indicate typical gadolinium found in 24-hour urine testing for each of the agents including Dotarem, Gadavist, Magnevist, MultiHance, Omniscan, OptiMARK, and ProHance. Since Gadolinium tends to deposit in bone and not remain in circulation, it could be that you are Gadolinium Toxic with negative test results. Methodology.

Testing would have to be arranged with a researcher who may be willing to test tissue specimens for evidence of Gadolinium. You can read about how to be tested in the Help -> Testing page on the website. If you have not done so yet, we recommend that you read the Study of Retained Gadolinium from Contrast MRIs and our latest report: Gadolinium Retention from Contrast MRIs in 70 Cases with Normal Renal Function – 24-hour Urine Test Results to understand the urine testing results that we have documented. With the evidence provided that clearance times are much longer for all of the agents than expected by medical practitioners, the authors present five recommendations for needed actions by medical professionals, other researchers, government agencies, and contrast agent manufacturers. 24-Hour volume is required. Gadolinium-Associated Plaques (GAP) in a patient without renal disease. For anyone who suspects that they may have gadolinium toxicity, they can get some insight from a 24-hour unprovoked urine test. The median lethal dose (LD50) of Gadolinium is roughly 100-200 mg/kg of body weight, but the dosage used for each MRI scan with contrast falls under this threshold. Types of Gadolinium Toxicity Testing Urine Testing.

If you understand the different aspects, you can put your results in perspective. Unfortunately, there are no specific treatments for gadolinium toxicity. Biopsy Testing is a more complex topic including two different types of tests – dermal biopsies for histological features similar to those found in NSF patients, and testing of tissue for the presence of Gadolinium. The reference range shows If we used 20, and IF you received a 3 gram EDTA IV, and IF you did a 23hr collection and IF the results were reported in mcg Gd/24hr, then that would indicate that your unprovoked result could be something like 0.13 mcg Gd/24hr. A 6-hour collection is often done for a provoked test since the time-effectiveness of the provoking agents is generally a couple hours, and the results would be lower if the collection was done for 24 hours.

Third, there are many different types of provoking agents that doctors may use as well as differences of oral chelators versus IV chelators. Since there are no established testing methodologies, none of the testing methods described below should be taken as the final word. Even though many participants in our Symptom Survey identified Dermal Issues as one of their symptoms, we are not aware of any positive dermal biopsy results for these individuals – either for the histological features of NSF or for the presence of Gadolinium. Therefore the dermal test is not relevant for things like muscle pain, paresthesias, cognitive issues, or ocular and ENT symptoms. In addition to reporting on additional cases received since our previous paper in 2017, we now report the contrast agents received with each unconfounded case. You will find information related to testing for Gadolinium, the symptoms of Gadolinium Toxicity, possible treatments, and more in the Help section. That tissue can also be tested for the presence of Gadolinium; however, to our knowledge, that testing is not available for purchase at any lab. Inductively Coupled … (more…), December 4, 2014 12:31 pm / Leave a comment. According to earlier studies, GBCA toxicity depends not on the presence of gadolinium, but on the strength of the chelating agent. There is no biopsy or laboratory test that can be used as a gold standard to diagnose NSF. However, the plasma half-life of Gadolinium is approximately 90 minutes. We have seen other with test results in that time frame that are around the level of your result, if your result is mcg Gd/24hr. shedding light on the effects of retained gadolinium from Contrast MRI. Results of a study to determine whether individuals with proposed gadolinium deposition disease (GDD) have elevated serum levels of pro-inflammatory and pro-fibrotic cytokines were recently published. It took approximately 6 months to collect the required sample size for each test. If you have skin changes and plan to have dermal tissue tested for NSF, it should be taken from an area with skin changes that are similar to what has been seen with NSF. A patient cannot purchase these tests directly from Genova Diagnostics. The analysis of clearance times for each agent is presented on a separate page. If you would like to learn more about the symptoms of gadolinium toxicity, read our Survey of the Chronic Effects of Retained Gadolinium from Contrast MRIs report. You need to pay attention to the units with the test, as some are reported as mcg Gd/24hr and some are reported as mcg Gd/g creatinine. <= 0.019. Blood Testing. Thank you for my ability to share my experience. The results reported are dramatic and involve all linear and macrocyclic GBCAs currently in use in the United States.

And having a lower level of Gadolinium in your urine long after your contrast MRI does not mean that you did not have a much higher level at earlier time points. Finding evidence of Gadolinium in tissue is not a criteria used in the diagnosis of NSF. Can Symptoms of Gadolinium Toxicity be explained? I'm cautiously optimistic! One we are aware of is Direct Labs. Gadolinium is highly toxic in "free" form, but when used in scanning it is administered in an intravenously injected liquid designed to make it safe. Thanks in advance. Your doctor can order the 24-hour test from Mayo Clinic Medical Laboratories through testing agencies like Quest Diagnostics and others.

Gadolinium toxicity lawsuits have been filed, with more lawsuits likely as patients become aware they may suffer from this condition. While a provoked test may identify a higher body burden of Gadolinium, these tests cannot easily be compared with results from other individuals because the specific provoking or chelating formula used by each doctor will significantly affect the test results. I was kept for quite some time for treatment to get my body to normal. Gadolinium had been reduced by 72%. After the competition of diagnostics I was getting dressed and noticed my face was swollen, then continued to look at the rest of my body and I had hives and welts covering face, neck, chest, arms, stomach, and legs.

First, a test can be either Provoked or Unprovoked as described in our Study of Retained Gadolinium from Contrast MRIs. Gadolinium Toxicity and Nephrogenic Systemic Fibrosis. It should be noted that the contrast agent and test result information presented is from people who believe they are suffering symptoms of gadolinium toxicity since their contrast-enhanced MRI. An elevated gadolinium in a specimen collected more than 96 hours after contrast media infusion does not definitively indicate risk of nephrogenic systemic fibrosis (NSF) or gadolinium toxicity. The safety profile of gadolinium (Gd)-based contrast agents (GBCAs) is generally considered excellent in most patients, including children from birth. For these reasons, we recommend an unprovoked 24-hour collection if you want to compare the results with others or track your levels over an extended time period. With the current status of Gadolinium Toxicity understanding by the medical community, there are no known and verified methods to know for sure if you are Gadolinium Toxic or have symptoms caused by Gadolinium.

See if you have toxic gadolinium levels by measuring the rare-metals element commonly used as an MRI contrast agent. The study by Maecker et al., “An initial investigation of serum cytokine levels in patients with gadolinium retention”, also sought to determine whether specific cytokines are correlated with certain symptoms considered to be characteristic of GDD. Blood test for gadolinium toxicity is another option. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours. Readers of the aforementioned Study wanted to know what symptoms the participants were experiencing. So that would certainly be within the Mayo range. Nephrogenic Fibrosing Dermopathy Associated with Exposure to Gadolinium-Containing Contrast Agents --- St. Louis, Missouri, 2002--2006 Nephrogenic fibrosing dermopathy (NFD) causes thickening and hardening of the skin, often in the extremities, and occurs in patients with underlying renal disease. High concentrations of gadolinium and iodine are known to interfere with most metal tests. Then the time of the start of the IV is the start of the 24hr Urine collection. Free gadolinium (Gd 3+) is a very toxic heavy metal because its ionic radius is very similar to that of calcium.Free gadolinium can block calcium channels and inhibit nerve transmissions, muscle contraction, blood coagulation, and mitochondrial function .Gadolinium can also replace calcium in bone . Gadolinium contrast is supplied under various names. What we have seen is that if the patient receives an EDTA IV of 3 grams, and does a 24hour urine collection, that the result will be somewhere around 20 times higher that their unprovoked level. A wellness doctor or a naturopathic doctor will be the best source for having urine testing conducted by Genova Diagnostics or Doctor’s Data independent clinical laboratories. Urine testing is the first step to a gadolinium toxicity diagnosis. Gadolinium Side Effects People who undergo an MRI scan with a gadolinium-based contrast agent, or GBCA, may experience coldness at the injection site, altered taste or the sensation known as pins and needles, depending on the brand of drug used. The significance of this case series is that neither patient had NSF; while one patient did have renal disease, the other patient did not. Most dermatopathology labs can test dermal biopsies for the histopathological features seen in NSF; however, most patients with normal kidney function do not present with the same, severe skin manifestations after Gadolinium retention. A Provoked test is done by collecting the urine sample after taking a provoking agent (or having an IV with a chelating formula) to attempt to ‘draw out’ additional toxic metals from tissues that would not have come out with an Unprovoked test.
