Description

Total T4 (Thyroxine) Test Kit

The T4 test kit is an in vitro diagnostic reagent used for quantitative measurement of total thyroxine (T4) in human serum or plasma. It is commonly used in thyroid function testing panels to evaluate metabolic and endocrine disorders.

Clinical Background

Thyroxine (T4) is a hormone produced by the thyroid gland. It plays a key role in:
● Metabolism regulation
● Growth and development
● Energy balance

Thyroid Testing System

T4 is not used alone. It is part of thyroid function testing:
● TSH (Thyroid Stimulating Hormone)
● T3 (Triiodothyronine)
● T4 (Thyroxine)

Combined interpretation helps diagnose:
Hypothyroidism (low thyroid function)
Hyperthyroidism (overactive thyroid)

Test Principle

The kit is based on:
● Fluorescence Immunoassay (FIA)
● Competitive binding detection principle
● Quantitative hormone measurement
