Treponema Pallidum by IHC
Also known as: TPALL IHC
Use
The test applies immunohistochemical staining to detect Treponema pallidum in formalin‑fixed, paraffin‑embedded tissue samples. It is intended to support clinical diagnosis by visually identifying the presence of Treponema organisms in tissue specimens. The test performance characteristics were developed and determined by ARUP Laboratories in a CLIA‑certified laboratory, for clinical purposes only. It has not been cleared or approved by the U.S. Food and Drug Administration.
Special Instructions
Not provided.
Limitations
The test has not been cleared or approved by the US Food and Drug Administration. It is limited to use as a stain‑and‑return technical service; results interpretation requires appropriate clinical correlation. It is validated on formalin‑fixed paraffin‑embedded tissue or cellblock preparations; nonrepresentative or depleted tissue specimens are unacceptable.
