Autoimmune Reactivity Screen

Measures predictive autoantibodies, some of which can appear up to 10 years before clinical symptoms. Efficiently and economically assesses possible tissue damage to multiple organs of the body.
Clinical Use:
- Measure Predictive Antibodies, some of which can appear up to ten years before the clinical onset of disease
- Economically and efficiently assess possible tissue damage to multiple organs of the body
Recommended for Patients Who:
- A diagnosed autoimmune disorder, as they commonly develop additional autoimmune conditions
- Chronic increased intestinal permeability, which is the gateway for environmentally-induced autoimmune disorders
Additional note on expanded array (Array 7X - Neurological Autoimmune Reactivity Screen):
By including IgM, Array 7X helps with early detection of neuro-autoimmune reactivity, the identification of multi-focal motor neuropathy, lower motor neuron syndromes, early development of relapses in multiple sclerosis and chronic inflammatory demyelinating polyneuropathy, and as a tool to monitor the effectiveness of related treatment protocols.

Optimal range: 0.5 - 2 ELISA IndexThyroglobulin IgG
Optimal range: 0 - 200 WHO units
Function:
Thyroglobulin (Tg) is a glycoprotein formed by two identical subunits. Tg is synthesized in thyrocytes and released into thyroid follicles where it is most abundant. Tg plays the main role in coupling of iodinized tyrosine residues to form hormones, triiodothyronine (T3) and thyroxine (T4), through its specific sites. In order to release these hormones, the thyroid gland has to reabsorb the Tg droplets from the follicular lumen into folicular cells. A small fraction of Tg (around 100 mcg) is released from thyroid on a daily basis.

Tropomyosin is a cytoskeletal microfilamental protein that regulates actin mechanics. Tropomyosin plays an important role in muscle contraction. Tropomyosin, along with the troponin complex, works with actin in muscle fibers and manages muscle contraction by regulating the binding of myosin. Tropomyosin isoforms are involved in the stabilization of actin filaments, intracellular organelle movement, cell-shape maintenance and cytokinesis.
