HPV mRNA E6/E7 with Reflex to HPV Genotypes 16, 18/45

Overview

  • EPIC Code:
  • LAB2952
  • Soft Test Code:
  • HPVRE
  • Send Out Test Code:
  • 90942
Alternate Names
  • E6/E7
  • Hologic
  • TMA w/ Reflex
Clinical Significance

The presence of E6/E7 messenger RNA from 14 high risk HPV types indicates incorporation of HPV DNA into the host cells. Proteins expressed from E6/E7 polycistronic mRNA alter cellular p53 and retinoblastoma protein functions, leading to disruption of cell-cycle check points and cell genome instability. This information, together with the physician's assessment of cytology history, other risk factors, and professional guidelines, may be used to guide patient management. This assay detects E6/E7 viral messenger RNA (mRNA) from 14 high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68).

HPV mRNA E6/E7 Not detected


Test Comments:

This test was performed using the APTIMA® HPV Assay (Gen-Probe Inc.).

This assay detects E6/E7 viral messenger RNA (mRNA) from 14 high-risk HPV types (16, 18, 31, 33, 35, 39, 45, 51, 52, 56, 58, 59, 66, 68).

If HPV mRNA E6/E7 is detected, HPV Genotypes 16, 18/45 will be performed at an additional charge (CPT Code(s): 87625).


Methodology:
  • Transcription-Mediated Amplification (TMA)
