Do not mix components from different kit lots or use reagents beyond the kit expiration date.
Allow all reagents to warm to room temperature for at least 30 minutes before opening.
Pre-rinse the pipet tip with reagent, use fresh pipet tips for each sample, standard and reagent to avoid contamination.
Unused wells must be kept desiccated at 4 C in the sealed bag provided.
Mix Thoroughly is very important for the result. It is recommended using low frequency oscillator or slight hand shaking every 10 minutes.
It is recommended that all samples and standards be assayed in duplicate or triplicate.

Gel pack with blue ice.

T4, the principal thyroid hormone largely bound to transport proteins, especially TBG. Given normal levels of thyroid hormone-binding proteins, hyperthyroidism is characterized by increased levels of circulating T4, hypothyroidism by decreased levels. Exceptions to this parallelism between thyroid status and total T4 concentration are found. Levels of TBG are known to be altered under various physiological, pharmacological and genetic conditions. Elevated T4 levels may be obtained when TBG levels are high, as in pregnancy, acute intermittent porphyria, hyperproteinemia, hereditary TBG elevation and in patients undergoing estrogen therapy or taking oral contraceptives. Total T4 levels may be depressed when TBG levels are low, as in nephrotic, hepatic, gastrointestinal and neoplastic disorders; in acromegaly, hypoproteinemia and hereditary TBG deficiency; and in patients undergoing androgen, testosterone or anabolic steroid therapy.
