This is a blood test that looks for various antibodies, typically ordered by doctors for use in conjunction with clinical findings to monitor conditions including Wegener granulomatous (WG) disease.
The results include:
- Antimyeloperoxidase (MPO) antibodies
- Antiproteinase 3 (PR3) antibodies
- Cytoplasmic antineutrophil cytoplasmic antibodies (cANCA)
- Perinuclear antineutrophil cytoplasmic antibodies (pANCA)
Expected turnaround is 3-7 days, although this can vary depending on other tests ordered for the same blood draw, and expected variation in test handling.
