*  Final Diagnosis -- Case 686
Figure 2: The Effects of Endogenous Thyroglobulin Antibody on the Measurement of Serum Thyroglobulin using Immunoenzymatic (Sandwich) Method. Thyroglobulin Immunoassays. Several immunoassays are commercially available to measure thyroglobulin including the competitive radioimmunoassay (RIA) and the one-step immunoenzymatic (sandwich) assay (IMA). The RIA method is older and more labor intensive compared to IMA. In the RIA method, thyroglobulin competes with 125I labeled human thyroglobulin for a rabbit antibody against human thyroglobulin. After six days of incubation, thyroglobulin - antibody complexes are precipitated with a second anti-rabbit antibody. This method can detect both free thyroglobulin and thyroglobulin bound to antibody. The radioactivity is inversely proportional to the thyroglobulin concentration (2). In ...
*  Blood Test: Thyroglobulin Antibodies (TgAb)
A thyroglobulin antibodies (TgAb) test is used to check blood levels of antibodies the body has made against the compound thyroglobulin. Thyroglobulin is a protein produced and used by the thyroid gland (the small, butterfly-shaped gland in the neck) to make the hormones triiodothyronine (T3) and thyroxine (T4), both of which help control metabolism and growth.. Ordinarily, a healthy immune system wouldn't make significant levels of antibodies against thyroglobulin, because it's not "foreign," but rather a necessary component of thyroid functioning.. Antibodies are proteins made by the immune system to fight bacteria, viruses, and toxins.. In autoimmune diseases, however, the immune system malfunctions, mistakenly attacking healthy organs and tissues as though they were foreign invaders. In people with certain thyroid-related autoimmune conditions, the blood level of thyroglobulin antibodies may rise.. ...
*  Microbiology Society Journals | Purification and Characterisation of Clostridium Difficile Toxin A by Bovine Thyroglobulin...
Highly purified toxin A of Clostridium difficile was obtained by bovine thyroglobulin affinity chromatography followed by two sequential anion-exchange chromatography steps on Q Sepharose FF and Mono Q. After Q Sepharose FF chromatography of a thyroglobulin affinity-purified toxin A preparation, two major peaks of cytotoxicity representing toxins A and B were detected. The homogeneity of the final toxin A preparation obtained from Mono Q anion-exchange fast protein liquid chromatography was ascertained by gel electrophoresis developed by silver stain. The mol. wt of toxin A in non-denaturing conditions was estimated to be 520-540 Kda by native polyacrylamide gel electrophoresis (PAGE) developed by silver stain. In contrast, with sodium dodecyl sulphate (SDS)-PAGE under reducing or non-reducing conditions, a major band of 240 Kda and 10 minor and 27 faint bands (non-reduced conditions), or four minor and 31 faint bands (reduced conditions) were detected after silver staining. ...
*  Current Thyroglobulin Autoantibody (TgAb) Assays Often Fail to Detect Interfering TgAb that Can Result in the Reporting of...
Spencer C , Petrovic I , Fatemi S. J Clin Endocrinol Metab. 2011 May;96(5):1283-91.. Specimens have thyroglobulin antibody (TgAb) measured prior to thyroglobulin (Tg) testing because the qualitative TgAb status (positive or negative) determines risk for Tg assay interference, and the quantitative TgAb concentration serves as a surrogate tumor marker for differentiated thyroid cancer. This study assessed the reliability of four TgAb methods to detect interfering TgAb [as judged from abnormally low Tg immunometric assay (IMA) to Tg RIA ratios] and determine whether between-method conversion factors might prevent a change in method from disrupting TgAb monitoring. Sera from selected and unselected TgAb-negative and TgAb-positive differentiated thyroid cancer patients had serum Tg measured by both IMA and RIA and TgAb measured by a reference method and three additional methods.: The Tg IMA and Tg RIA values were concordant when TgAb was absent. Tg IMA to Tg RIA ratios below 75% ...
*  Ask an Expert: Thyroglobulin with goiter on neck
I have a goiter in the neck. My blood report of my thyroid is below: T3 0.96 ng/mL ( 0.8 - 2 ) T4 6.49 ng/dL ( 5.1 - 14.1 ) FT4 1.25 ng/dL ( 0.93 - 1.7 ) TSH 1.7 mIU/L ( 0.27 - 4.2 ) Thyroglobulin (TG) 180.1 ng/mL ( 1.4 - 78 ) Before the T3 and T4 is not normal, after medicine become normal. My doctor says that because the Thyroglobulin TG is so high, it might be cancer. Doctor says I need to have a general surgeon cut half of the thyroid, and after cut out, check out if the goiter is cancer and needs to cut the other side of my thyroid. In here I want to ask, without surgery, in what way can it be determined if my thyroid is a cancer tumor or not? If there is no way to know about it, what kind of surgery is good? Hope doctor can help me. And one more question, Thyroglobulin TG is that the same of Thyroglobulin Antibody? Thank your very much. ...

*  TPO/TG Antibodies Test - FunctionalCure
A thyroid test should be something done regularly. Autoimmunity can be detected due to the increased antibodies found in blood, and comparing them with those that are found within the thyroid glands. This can effectively tell whether the thyroid is under attack by one's own immune system. In associations with Hashimoto's, thyroglobulin and thyroid peroxidase antibodies are the most pronounced.. The TPO/TG antibodies test can be used to diagnose both Grave's antibodies and TSH receptor antibodies. This test can detect minute increase in the number of antibodies even before there is visible change in the amount of TSH. The difference in the two conditions should be adequately expounded by one's GP.. Hashimoto's usually develops as a result of increased release of thyroid peroxidase antibodies and thyroglobulin antibodies above 35 in each.. Having these antibodies elevated beyond 35 predisposes one to develop hypothyroidism before the end of a decade. Information on the level ...

*  Losing the Butterfly: March 2017
so, let's talk about thyroid medication dosing. there are several reasons that this is important. it is extremely important to keep the TSH at a level to suppress the possible stimulation of thyroglobulin. just as a reminder, only thyroid cells produce thyroglobulin. if you do not have a thyroid gland in your body, and you test positive for the presence of thyroglobulin( this should be part of your blood work test), that means that you have, most likely, thyroid cancer cells somewhere else in your body. unfortunately, there is also another factor that adds to the excitement, and that is that some people ( me included) produce thyroglobulin antibodies. this makes the test for thyroglobulin rather difficult to interpret. in my case, i tested positive for the thyroglobulin( TG) the first year, as well as the antibodies. for the next two and a half years, i tested positive for just the antibodies. my physician ...
*  Thyroid-stimulating hormone, thyroglobulin, and thyroid hormones and risk of differentiated thyroid carcinoma : the EPIC study
Background Increased levels of thyroglobulin (Tg) and thyroid-stimulating hormone (TSH) are associated with differentiated thyroid carcinoma (TC) risk, but strong epidemiological evidence is lacking. Methods Three hundred fifty-seven incident TC case patients (n = 300 women and 57 men; mean age at blood collection = 51.5 years) were identified in the EPIC cohort study and matched with 2 (women) or 3 (men) control subjects using incidence density sampling. Matching included study center, sex, age, date, time, and fasting status at blood collection. Levels of total and free (f) thyroxine (T4) and triiodo-thyronine (T3), TSH, Tg, and anti-Tg antibodies (TgAb) were measured by commercially available immunoassays. Odds ratios (ORs) and 95% confidence intervals (CIs) were computed using conditional logistic regression. All statistical tests were two-sided. Results TC risk was positively associated with Tg (OR for the highest vs lowest quartile = 9.15; 95% CI = 5.28 to 15.90; P , .001) and ...
