TT4 is the main product of thyroid secretion and is an essential ingredient in the integrity of the hypothalamic-pituitary gland. The TT4 measures can be used for the diagnosis of hyperthyroidism, primary and secondary, and TT4 inhibition of treatment.
TT4 Rapid Quantitative Test (Chemiluminescence Immunoassay) is used for in vitro quantitative detection of the total thyroxine 4 (TT4) concentration in human serum, plasma that contains heparin /EDTA and other anticoagulants and venous whole blood samples, mainly used for auxiliary diagnosis of thyroid diseases.
The Biotime TSH/TT3/TT4Rapid Quantitative Testis intended to quantitatively detect theconcentration of thyroid stimulating hormone (TSH),total triiodothyronine (TT3) and total thyroxine (TT4) in human serum and plasma samples on Biotime FIA Analyzer byfluorescent immunoassay. The test is used as an aiddiagnosis of thyroiddisease. For in vitro diagnostic use only. For professional use only.
