LP40007-4 Thyrotropin receptor Ab
Thyrotropin receptor antibodies (TRAb) are autoantibodies to the thyroid-stimulating hormone receptor antigen.[PMID17900238] TRAb can be stimulating, blocking or growth-promoting to the thyroid leading to hyperthyroidism, hypothyroidism and endemic or sporadic goiters, respectively. PMID: 1633635 TRAb can be used to predict short-term reoccurrences of hyperthyroidism post antithyroid medication but is less capable of predicting long-term relapses or remissions. Increased TRAb in pregnant women with Graves' Disease is a risk factor for fetal hyperthyroidism. Patients with GD who have elevated TRAb are more likely to develop Graves' ophthalmopathy than GD patients with lower titers. PMID: 23539719 Source: Regenstrief LOINC

Additional Names

Long Common Name: Thyrotropin receptor Ab [Units/volume] in Serum by Immunoassay
Short Name: TSH Recep Ab Ser IA-aCnc

Basic Attributes

Class: SERO
Type: Laboratory
First Released: Version 2.29
Last Updated: Version 2.73 (MIN)
Change Reason: The EIA method, which was always intended to cover more than just enzyme-linked immunoassay and whose display name for the long common name has always been Immunoassay, was renamed IA in order to eliminate ambiguity about whether the method has a broader meaning than just enzyme-linked immunoassay. Likewise, EIA.rapid was renamed IA.rapid. These changes were approved by the Laboratory LOINC Committee in June 2016.
Order vs. Observation: Both
