General description

Thyroxine or T4 is a thyroid hormone responsible for regulation of the body′s basal metabolic rate and essential for growth, development and heart and nervous system function. Free and total T4 serum levels are measured by LC-MS/MS for determination of hyper- or hypothyroidism as well as for monitoring treatment with synthetic thyroid hormones. This Certified Spiking Solution® is suitable for use in LC-MS/MS testing methods as starting materials in preparation of linearity standards, calibrators, and controls.

Biochem/physiol Actions

La L-tiroxina (T4) y la triyodo-L-tironina (T3) son hormonas que contienen yodo producidas a partir de la tiroglobulina en las células foliculares tiroideas. La estimulación de la tasa metabólica y la regulación del crecimiento y el desarrollo por esas hormonas parece deberse a sus efectos sobre la transcripción del ADN y, por tanto, la síntesis de proteínas.

BACKGROUND Previous meta-analyses of observational data indicate that pregnant women with subclinical hypothyroidism have an increased risk of adverse pregnancy outcome. Potential benefits of levothyroxine (LT4) supplementation remain unclear, and no systematic review or meta-analysis of trial findings is available
