HomeLab TestTSH receptor antibodies (TRAb)
Overview
The TRAb test measures the level of antibodies that target the thyroid-stimulating hormone (TSH) receptors in the body. Elevated TRAb levels are associated with autoimmune thyroid diseases such as Graves' disease.
Risk assessment
The TSH receptor antibodies (TRAb) test is a standard blood test with minimal risk. The primary risk is related to the blood draw, which may cause minor bruising, bleeding, or infection at the puncture site.
Ranges
Negative: Less than 1.75 IU/L Equivocal: 1.75 to 2.00 IU/L Positive: Greater than 2.00 IU/L.
Test result interpretation
Positive result: Elevated TRAb levels indicate the presence of antibodies that stimulate the thyroid gland, leading to hyperthyroidism. This finding is characteristic of Graves' disease.
Negative result: Normal TRAb levels suggest the absence of auto...
Sample types
A blood sample is required, typically drawn from a vein in the arm. The sample is then processed in the laboratory to measure TRAb levels.

Description
TSH receptor antibodies (TSHR-Ab) imitate the action of TSH and, by targeting these receptors, can trigger hyperthyroidism. TSHR-Abs are present in over 85% of people with Graves' disease and less commonly with Hashimoto's disease. As such, high levels of TSHR antibodies are strongly suggestive of Graves' disease.
