NKX3.1 Immunostain, Technical Component Only
Use
Homeobox NKX3.1 (NKX3.1) is a prostate-specific protein. Expression of NKX3.1 is used in the diagnosis of metastatic adenocarcinoma or ambiguous tumors that are from the prostatic origin. It is useful for identifying tumors of prostatic origin in a clinical setting.
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 at the reviewing pathologist's discretion at an additional charge.
Limitations
This test does not include pathologist interpretation, only technical performance of the stain. If interpretation is required, order PATHC / Pathology Consultation for a full diagnostic evaluation or second opinion of the case. Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. The charge of glass slides can be affected by environmental factors and may alter slide staining, resulting in inconsistent staining due to poor slide surface chemistry.
