TSH reference values for adult Brazilian population

Spirometry reference values in the Brazilian population

The aim of the present study was to provide new spirometry reference equations in a sample of the Brazilian population for the following parameters: forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), FEV1/FVC ratio, peak of expiratory flow (PEF), forced expiratory flow at 50% (FEF50%), 75% average vital capacity (FEF25-75%), and average forced expiratory flow time (FEFT)....

Determination of thyrotropin reference values in an adult Mexican population.

BACKGROUND AND OBJECTIVE The upper limit of TSH reference level is controversial. The purpose of our study was to determine TSH reference values in a Mexican population in accordance with the National Academy of Clinical Biochemistry (NACB) criteria and in correlation with thyroid ultrasound (US) examination. PATIENTS AND METHODS The study was conducted in volunteers with no known thyroid dis...

TSH reference range in older adults: a Brazilian study.

OBJECTIVE To establish serum TSH reference values for a population of Brazilian elderly, and to compare them to those found in the adult population. SUBJECTS AND METHODS Healthy volunteers aged 70 to 85 years, without known thyroid disease or risk factors for thyroid dysfunction, who did not use any medication that could potentially interfere with TSH, were selected.
