Free Thyroxine (FT4) radioimmunoassay kit (one step) RIA
The OCFD03-FT4-K kit is a one-step radioimmunoassay for free thyroxine (FT4) in serum to diagnose and monitor thyroid dysfunctions and treatments.
Diagnosis thyroid dysfunction
Assess thyroid metabolism precisely, in particular in the presence of changes in the binding proteins
Monitor drug therapies
- ONE STEP ASSAY BELOW 1 HOUR
- EXTENSIVE MEASUREMENT RANGE
The assay is based on a competition between 125I-FT4 and the FT4 contained in the samples for a fixed and limited number of anti-T4 polyclonal antibody binding sites adsorbed onto the walls of the tube.
One-step assay procedure: 45 min at 37°C / shaking.
Working range: 0.73 – 70 pg/mL (0.95-91pmol/L)
Sample: serum – 50 µL
Analytical sensitivity: 0.73 pg/mL (0.95 pmol/L)
|Population||n||T4L pg/mL||T4L pmol/L|
|Euthyroidism||858||7 – 18||9 – 23.2|
