Plasma Carnitines: Reference Values in an Ambulatory Population

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...

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)....

Reference Values for Serum Total Cholesterol Concentrations Using Percentile Regression Model: A Population Study in Mashhad

Background and Purpose: Serum total cholesterol (TC) concentrations are affected by several factors including ethnicity, diet, geographic, and environmental determinants, and are related to another disease, including hypothyroidism, and renal and liver disease. It is associated with an increased risk of cardiovascular disease, particularly if associated with high levels of serum low-density lip...

Spirometric reference values for an adult Rwandan population. (East Africa)

Spirometric reference values for an East-African population.

BACKGROUND Accurate interpretation of lung function testing requires appropriate reference values. Unfortunately, few African countries have produced spirometric reference values for their populations. OBJECTIVES The present study was carried out in order to establish normal lung function values for subjects living in Rwanda, East Africa. METHODS The study was conducted in Kigali, capital o...
