PRODUCT NAME: |
ST AIA-PACK FT4 |
INTENDED USE: |
ST AIA-PACK FT4 is designed for IN-VITRO DIAGNOSTIC USE for the quantitative measurement of non-protein-bound (free) thyroxine (FT4) in human serum or heparinized plasma on Tosoh AIA immunoassay analyzers. |
SUMMARY AND EXPLANATION OF TEST: |
Thyroxine (T4) is produced by the thyroid gland and 99.97% of T4 circulates in the blood in a bound form with the plasma proteins including thyroxine-binding globulin (TBG), thyroxine-binding prealbumin (TBPA) and albumin. Approximately 0.03 % of the total circulating thyroxine is unbound. Historically measurement of total serum T4 (bound + free) is used to assess the clinical status of the Thyroid gland. But free T4 (FT4) is believed to be the physiologically active portion of the thyroxine which stimulates the metabolism and controls, via the pituitary, the feedback system involving the release of TSH. Therefore measurement of free T4 (FT4) typically co-relates more closely to the patient's actual thyroid status. |
