Understanding Lab Tests for Autoimmune Thyroid Disease
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Autoimmune thyroid diseases, including Hashimoto's thyroiditis and Graves' disease, occur when the immune system mistakenly attacks the thyroid gland. These conditions can be accurately diagnosed through specific blood tests that detect thyroid antibodies and measure thyroid function.
Recommended Test
Parietal Cell Antibody, ELISA
This test detects antibodies against parietal cells in the stomach. Parietal cell antibodies are frequently found in patients with autoimmune thyroid diseases, as these conditions often occur together. Testing for these antibodies can help identify potential gastric autoimmune involvement and assess the broader autoimmune process affecting multiple organ systems.

Diagnosing Autoimmune Thyroid Disease
Blood tests are the primary diagnostic tools for autoimmune thyroid diseases. These tests can detect specific antibodies that target thyroid tissue, measure thyroid hormone levels, and assess overall thyroid function. Early detection through testing allows for appropriate treatment to manage symptoms and prevent complications.
Additional Testing for Related Autoimmune Conditions
Individuals with autoimmune thyroid disease often have an increased risk of developing other autoimmune conditions. Testing for additional antibodies can help identify these related conditions and provide a more comprehensive assessment of autoimmune activity.
Understanding Your Results
Positive antibody tests indicate autoimmune activity, but results should always be interpreted alongside symptoms and clinical findings. Your healthcare provider will use these test results along with other thyroid function tests to develop an appropriate treatment plan.
