124 Possible Causes for ENZYME, IMMUNOASSAY,, INHIBIN A

Show results in: Română

  • Endocrine Dysfunction

    No relationship between repeat size and inhibin concentrations in PMC.[] […] 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).[]

  • Granulosa Cell Tumor

    OBJECTIVE: Here, we report a case of secondary amenorrhea with low serum luteinizing hormone and follicle-stimulating hormone levels due to an inhibin A- and inhibin B-producing[] In addition it would open a new line of research with CYP17 enzyme inhibitors that could alter the course and outcome, usually fatal, in advanced stages of disease.[] The cohort of young women had expected normal values of AMH as measurable by the same immunoassay kit.[]

  • Aromatase Deficiency

    In normal girls, serum estradiol concentrations strongly correlate with circulating inhibin levels, and thus, low inhibin levels may contribute to the striking elevation of[] OBJECTIVE: Aromatase, or CYP19A1, is a type II cytochrome CYP450 enzyme that catalyzes the conversion of C19 androgens to C18 estrogens.[] As is the case with many immunoassays, heterophilic antibodies can cause false-positive results.[]

  • Congenital Adrenal Hyperplasia due to 21-Hydroxylase Deficiency

    In all children with TART, LH, FSH, testosterone and inhibin B levels were similar to the patients without TART.[] Short description: Congenital adrenogenital disorders assoc w enzyme deficiency The 2019 edition of ICD-10-CM E25.0 became effective on October 1, 2018.[] Traditional screening by enzyme immunoassay results in a large number of false positives.[]

  • HIV-2 Infection

    A & B Tumor Marker Chemistry 11/14/2017 Inhibin A Tumor Marker Chemistry 11/14/2017 Inhibin B Chemistry 12/20/2017 Inner Ear Antigen Serology 02/04/2016 Instructions for[] From Wikipedia, the free encyclopedia Jump to navigation Jump to search HIV-2 retropepsin ( EC ) is an enzyme . [1] [2] This enzyme catalyses the following chemical[] The results of a commercial enzyme immunoassay specific for HIV-1 antibody were positive in both cases, but those of the Western blot technique were indeterminate.[]

  • Sertoli Cell-Only Syndrome

    RESULTS: All specimens showed intense staining for the inhibin alpha subunit. Moderate or intense staining for GDNF was observed in 65.8% of specimens.[] Deoxyribonucleic acid samples from controls and study subjects were digested with the restriction enzymes TaqI, EcoRI, and BamHI.[] An enzyme linked immunoassay for anti-Mullerian hormone: New tool for the evaluation of testicular function in infants and children.[]

  • Granulosa Cell Tumor of the Ovary

    Her elevated serum FSH after the operation was the result of a decreased serum level of inhibin that had been produced by the tumor.[] Juvenile Granulosa Cell Tumors [ edit ] Two recent studies show that the enzyme AKT1 is involved in juvenile granulosa cell tumors.[] The frequency of elevated levels varies amongst studies, likely due to the different specificities of the antibodies used in the immunoassays.[]

  • Sertoli Leydig Cell Tumor

    Early evaluation of the hypothalamic-pituitary-ovarian axis and inhibin levels is appropriate.[] For enzyme histochemical purposes the tumor tissue, removed from the right ovary by laparatomy, was frozen in liquid nitrogen.[] Estimation of androstenedione, by Radio-ImmunoAssay (RIA), showed a high value of 5.38 ng/ml (the normal value for adult female being 0.47-2.68 ng/ml.)[]

  • Adrenogenital Syndrome

    In pubertal or postpubertal CAH patients, oligo or azoospermia may already be found due to obstruction of the seminiferous tubules Signs of gonadal dysfunction: decreased inhibin[] […] is affected by deficiency of a specific enzyme.[] The clinical manifestation of the disease is largely dependent on the type and degree of enzyme deficiency.[]

  • Epithelioid Trophoblastic Tumor

    The tumor cells were positive for cytokeratin, inhibin-alpha, and melanoma cell adhesion molecule (Mel-CAM, CD146) but were only focally positive for human placental lactogen[] […] specific enzymes produced more if the malignancy arises in organisms, so it can be used as a tumor marker . 1. prostatic acid phosphatase (PAP) is an enzyme produced by the[] However, light microscopic findings and immunohistochemical studies with pan-cytokeratin, epithelial membrane antigen, inhibin-alpha, beta-hCG, and human placental lactogen[]
