  • Thyroxine

    […] nmol/L (total T3).[] ABBREVIATIONS: T4: L-Thyroxine; ELISA: Enzyme-linked immunosorbent assay; SUMA: Ultra Micro Analytic System; UMELISA: Ultramicro enzyme-linked immunosorbent assay; TSH: Thyroid-stimulating[] Abstract Interference in immunoassays is a widely recognized problem, which could potentially lead to unnecessary investigations and treatment.[] Each of our ultra-pure radiolabeled compounds is fully characterized for pharmacological action and validated in binding assays.[] She required increasing doses of thyroxine but remained hypothyroid. Daily and weekly supervised thyroxine administration strategies were unsuccessful.[]

  • Triiodothyronine

    Normal Source 1 T3 Total Cord blood ( 37 weks) 5 to 141 ng/dL 1 to 3 days 100 to 740 ng/dL 1 to 11 months 105 to 245 Children 1 -5 years 105 to 269 ng/dL 6 to 10 years 94[] KEYWORDS: Enzyme inhibition; UDP-glucuronosyltransferases; thyroxine; triiodothyronine[] Abstract Thyroxine-binding globulin (TBG) excess with increased total thyroxine (T4) and triiodothyronine (T3) levels has not been thought to produce symptoms.[] OBJECTIVE: We compared the performance of tandem mass spectrometry versus immunoassay for measuring thyroid hormones in a diverse group of inpatients and outpatients.[] Total T3 consists of both the bound and unbound fractions.[]

  • Endocrine Dysfunction

    Serum total thyroxine was normal in every patient, while serum total triiodothyronine was low in six; in these six patients serum triiodothyronine normalised with treatment[] […] concentrations of total serum estradiol and serum estradiol not bound to sex hormone-binding globulin, (b) impaired spermatogenesis and sperm motility, and (c) blocking of multiple enzymes[] Typically, this may cause positive interference in competitive immunoassays (FT4 and FT3) and negative interference sandwich immunoassays (TSH).[] INTERVENTIONS: Ten of the 18 patients received enzyme replacement therapy (ERT) with recombinant human alpha-galactosidase-A (agalsidase beta) at a dose of 1 mg/kg body weight[] Thyroid hormone levels (total and free fraction) were essentially normal.[]

  • Osteoporosis

    RESULTS: A total of 10 trials with a total of 1042 patients were included.[] The predominant expression of cathepsin K in osteoclasts has rendered the enzyme into a major target for the development of novel anti-resorptive drugs in osteoporosis whereas[] Undercarboxylated osteocalcin measured with a specific immunoassay predicts hip fracture in elderly women: the EPIDOS Study. J Clin Endocrinol Metab 1997;82:719–24.[] […] observed here (OR, 1.77) and previously (OR, 1.7) 36 suggests that part of the possible benefit of β-adrenergic antagonists could be mediated via the known inhibition of thyroxine[] McComb RB, Bowers GN Jr. (1985) Alkaline phosphatase and the international clinical enzyme scale. Am J Clin Pathol 84(1):67–73 CrossRef PubMed Google Scholar 12.[]

  • Adrenal Insufficiency

    […] free serum cortisol directly as well as the difficulties in calculating an estimated free cortisol from total cortisol, CBG and albumin concentrations.[] Patients with partial deficiencies of steroidogenic enzymes are at risk to be misdiagnosed if adrenal function is not assessed.[] Patients underwent clinical examination and a fasting blood sample was collected to measure glucose, urea, creatinine, sodium, potassium, cortisol, growth hormone and free thyroxine[] Adrenal crisis is especially likely if a patient is treated for a single endocrine gland problem, particularly with thyroxine, without hydrocortisone replacement.[] The cortisol levels will be determined by competitive immunoassay using direct chemoluminescence technology (Bayer Corporation, Pittsburgh, PA, USA).[]

  • Euthyroid Sick Syndrome

    MEASUREMENTS AND RESULTS: Immediately on admission and on day 7 the following parameters were determined: total thyroxine (T4), free thyroxine (FT4), total triiodothyronine[] Diminished enzyme activity accounts for decreased deiodination of T4 to T3. Type 1 deiodinase enzyme deiodinates T4 to T3.[] Fillee C, Cumps J, Ketelslegers JM: Comparison of three free T 4 (FT 4 ) and free T 3 (FT 3 ) immunoassays in healthy subjects and patients with thyroid diseases and severe[] thyroxine (FT4) assay ("Amerlex').[] INTERVENTIONS: Blood was analyzed for serum concentration of total thyroxine (TT4), total triiodothyronine (TT3), free T3 (fT3), reverse T3 (rT3), and thyroid stimulating[]

  • Testosterone

    […] to total testosterone in the above situations.[] Further, in vitro enzyme assays demonstrated depressed activities of testicular 3beta-HSD and 17beta-HSD enzymes.[] […] kits with conventional radio and enzyme immunoassays.[] […] will be needed to establish the non-genomic actions of testosterone and its functionality in platelets.[] The postoperative hormonal profile showed normalization of FSH and low LH, testosterone, morning cortisol level, and free thyroxine.[]

  • Acute Gastroenteritis

    A total of 11 rectal samples and 8 barrelled water samples were detected as norovirus-positive, and the genotypes of viral strains were the same (GII).[] Stool was tested for presence of rotavirus using an enzyme immunoassay kit.[] OBJECTIVES: We assessed the diagnostic performance of rectal swabs compared to bulk stools for the detection of rotavirus by Enzyme Immunoassay (EIA) and multiplex semi-nested[] In total, 156 fecal samples were screened by RT-PCR for SaVs. A positivity rate of 3.8% (6/156) was found in children under three years of age.[] METHODS: Two hundred and ninety eight specimen from children presented at Gertrude Childrens' Hospital from January to June 2012 were tested by EIA (Enzyme-linked Immunosorbent[]

    Missing: NON RADIOLABELED Thyroxine
  • Statin

    Background: Limited data are available on the efficacy of statin therapy in stable ischemic heart disease with chronic total occlusion (CTO) without revascularization.[] Of late, use of co-enzyme Q10 has become acceptable for the muscle side effects.[] After intravenous administration of radiolabeled pravastatin to normal volunteers, approximately 47% of total body clearance was via renal excretion and 53% by non-renal routes[] This was confirmed by normalisation of LDL-C upon discontinuation of amiodarone and treatment with thyroxine.[] Quantification of human apolipoprotein E in plasma and lipoprotein subfractions by a non-competitive enzyme immunoassay.[]

  • Thyroid Dysfunction

    CONCLUSION: The total number of doses administered may be a risk factor for the development of thyroid dysfunction after nivolumab therapy.[] She also had the features of hypothyroidism, namely mounding phenomenon, muscle rigidity, increased plasma myogenic enzymes and cold intolerance.[] […] who underwent a nationwide Korean representative sampling and cross-sectional survey with blood collection for a thyroid function test using an electrochemiluminescence immunoassay[] Similarly, participants who had ever been on thyroxine medication (n 77; 8.4%) compared to those who had never been on thyroxine (n 829) also had a higher risk of any AMD,[] The iodide trapped by the thyroid gland is subsequently oxidized to iodine by the enzyme thyroid peroxidase.[]
