Reference Values
Describes reference intervals and additional information for interpretation of test results. May include intervals based on age and sex when appropriate. Intervals are Mayo-derived, unless otherwise designated. If an interpretive report is provided, the reference value field will state this.
Anti-Thyroid Peroxidase IgG: <35 IU/mL
Anti-Thyroglobulin IgG: <40 IU/mL
TSH (Thyrotropin): 0.4-4.0 uIU/mL
CU Index: <10.0
The CU Index test is the second generation Functional Anti-FceR test. Patients with a CU Index greater than or equal to 10 have basophil reactive factors in their serum which supports and autoimmune basis for disease.
