TAU 4 Immunostain, Technical Component Only
Use
The Tau 4 antibody stains microtubule-associated proteins in the brain that are associated with diseases of the central nervous system, especially neurodegenerative disorders. This test aids in the diagnosis of neurodegenerative disorders.
Special Instructions
This test includes only technical performance of the stain; no pathologist interpretation is provided. Technical component only stains should not be ordered with PATHC / Pathology Consultation. If ordered with PATHC, the technical component stains will be canceled. Any immunohistochemistry (IHC)/in situ hybridization (ISH) stain performed as a part of the PATHC will be performed at the reviewing pathologist's discretion at an additional charge.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. Interpretation should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. Sending unsuitable glass slides can result in inconsistent staining.
