The process ofageing is to a large extent due to the damagingconsequence of free radical action (lipid peroxidation,DNA damage, protein oxidation) (Harman, 1956).Convincing evidence for the association ofoxidative/ nitrosative stress and acute and chronicdiseases lies on validated biomarkers of oxidativestress.
The radioactive iodine uptake test, or RAIU test, is a type of scan used in the diagnosis of thyroid problems, particularly hyperthyroidism.he normal uptake is between 15 and 25 percent, but this may be forced down if, in the meantime, the patient has eaten foods high in iodine, such as dairy products and seafood. Low uptake suggests thyroiditis, high uptake suggests Graves' disease, and unevenness in uptake suggests the presence of a nodule.
As you know from this article a normal TSH range depending on the lab is around 0.5 to 5.0 which is why your TSH of 4.46 was determined normal, however the very fact that your first TSH test showed up 6.49 should be reason to investigate further.herefore a high TSH level suggests an underactive thyroid (hypothyroidism), while a low TSH indicates too much thyroid hormone in the body (hyperthyroidism). In my post âMiscarriage in New York Cityâ¦Be Thyroid Awareâ , I outlined the TSH ranges for pregnancy and provided trimester-specific ranges.
