A scientist examines a molecular model of triiodothyronine in a laboratory.

Definition

Noun: 1. A thyroid hormone: Triiodothyronine is a hormone produced by the thyroid gland. It is chemically similar to thyroxine but contains three iodine atoms per molecule instead of four. It is more potent and acts more quickly than thyroxine, though it is produced in smaller amounts. It plays a crucial role in regulating the body's metabolism, growth, and development.

Usage Examples

• Noun:
  • The blood test measures levels of triiodothyronine to assess thyroid function.
  • Triiodothyronine is often abbreviated as T3 in medical reports.
  • An overactive thyroid can lead to excessive production of triiodothyronine.

Advanced Usage

• "Free triiodothyronine" (FT3): This refers to the fraction of triiodothyronine in the blood that is not bound to proteins and is therefore biologically active. Measuring FT3 can provide a more accurate picture of thyroid activity.
  • The doctor ordered a free triiodothyronine test for a precise diagnosis.

Variants and Related Words

• T3: The common abbreviation for triiodothyronine.
  • The patient's T3 levels were within the normal range.
• Liothyronine: The synthetic form of triiodothyronine used as a medication.
  • Liothyronine is prescribed to treat hypothyroidism.

Synonyms

• T3 (Abbreviation): The standard medical shorthand.
• Liothyronine (When referring to the pharmaceutical preparation).
