TPO and Acetylcholine Receptor Antibodies
This week, we’re highlighting two key markers used in the investigation of autoimmune diseases affecting the thyroid and neuromuscular junction.
-
Thyroid Peroxidase (TPO) Antibody is commonly found in autoimmune thyroid disorders such as Hashimoto’s thyroiditis and autoimmune hypothyroidism, and plays a central role in thyroid antibody testing panels.
-
Acetylcholine Receptor (AChR) Antibody is a critical marker in the diagnosis of Myasthenia Gravis, a chronic autoimmune condition that affects neuromuscular transmission. It may also be found in related conditions such as thymoma-associated syndromes.
We offer human plasma and serum samples tested positive for both markers. Each sample is supported by in-house testing data and available in 1 mL or bulk volumes, depending on your workflow.
Samples are available in 1 mL and bulk volumes. If you'd like to request a free evaluation sample, reach out to us at info@abbaltis.com.
