Latest Patents

Johann Berger holds a patent for a process titled "Process for the quantitative determination of free thyroxine." This invention provides a method for determining free thyroxine (FT4) in plasma, serum, or whole blood using immunological techniques. The process involves incubating the sample with a 10 to 2000 fold insufficiency of labeled anti-T4 antibodies, relative to the total T4 in the sample. Following this, the sample is combined with immobilized excess T4, incubated again, and the phases are separated to measure the label in one of the phases. This innovative approach allows for rapid and accurate testing, enhancing the efficiency of thyroid function assessments.
