WebMethods in biochemistry. Like other sciences, biochemistry aims at quantifying, or measuring, results, sometimes with sophisticated instrumentation. The earliest approach to a study of the events in a living organism was an analysis of the materials entering an organism (foods, oxygen) and those leaving (excretion products, carbon dioxide). WebSerum TSH has a laboratory reference range of 0.270–4.20 µIU/mL, and the laboratory reference range for free T4 is 12–22 pmol/L. Serum-free T3 (laboratory reference range 3.1–6.8 pmol/L) was also measured. Subclinical hypothyroidism was defined as free T3 and free T4 in the normal reference range, while TSH values were >4.6 and <10 µIU/mL. WebD. Catalase Activity. Procedure: 1.
