Serum thyroid-stimulating-hormone concentration as an index of severity of major depression

Serum thyroid-stimulating-hormone concentration as an index of severity of major depression.

Alterations in thyroid axis are common in depression and subclinical hypothyroidism may predispose to recurrent depressive episodes and resistance to antidepressants. The same normal reference ranges are used in both depressive and non-psychiatric patients to detect hypothyroidism. We hypothesized that in depressive patients, serum TSH (thyrotropin) elevation within the normal reference range (...

THYROID FUNCTION TESTS Thyroid Stimulating Hormone (TSH): The thyroid stimulating hormone (TSH) assay measures the concentration of thyroid stimulating hormone in the serum. TSH assays

The thyroid stimulating hormone (TSH) assay measures the concentration of thyroid stimulating hormone in the serum. TSH assays have been classified by "generation" based on the functional sensitivity of the assay, i.e., the lowest concentration at which the assay is able to maintain an inter-assay precision, expressed in terms of percent coefficient of variation (%CV), of 20% or less. Virtually...

Evaluation of Serum Thyroid‐Stimulating Hormone Concentration as a Diagnostic Test for Hyperthyroidism in Cats

BACKGROUND In humans, measurement of serum thyroid-stimulating hormone (TSH) concentration is commonly used as a first-line discriminatory test of thyroid function. Recent reports indicate that canine TSH (cTSH) assays can be used to measure feline TSH and results can help diagnose or exclude hyperthyroidism. OBJECTIVES To investigate the usefulness of cTSH measurements as a diagnostic test f...

Thyroid Stimulating Hormone Thyroid Stimulating Hormone

Influence of serum levels of thyroid-stimulating hormone and anti-thyroid peroxidase antibodies, age and gender on depression as measured by the Zung Self-Rating Depression Scale.

UNLABELLED The AIM of the present study was to explore the level of depression in the respondents using the Zung self-rating depression scale (SDS) and find a correlation with the levels of the thyroid-stimulating hormone (TSH) and the anti-thyroid peroxidase antibodies (anti-TPO), the age and gender of the participants. PATIENTS AND METHODS 2401 subjects aged 20-84 yrs were included, 1344 of...
