Part Descriptions

LP17727-6 Thyroperoxidase
Thyroid peroxidase is an enzyime that is required in order for iodine to be added to the protein thyroglobulin, a precursor to the generation of thyroid hormones which are important in the physical growth, brain development and metabolism of the body. If thyroid peroxidase is not produced or blocked by antibodies, hypothyroidism occurs. Symptoms of hypothyroidism include fatigue, weight gain, muscle weakness, increased cholesterol levels, depression and impaired memory. [MedlinePlus Gene:TPO] Source: Regenstrief LOINC

LP40001-7 Thyroperoxidase Ab
Thyroperoxidase antibodies aid in the detection of autoimmune and Hashimoto's thyroiditis. Antibodies against the thyroid are seldom seen in serum of normal individuals but 5-10% of patients may have low levels of antibodies with no signs of disease. These antibodies maybe associated with other autoimmune disorders (cross-reactive antibodies). Source: Regenstrief Institute
