Autoantibodies can fluctuate over time, and they may also be negative at times. Treatment and the level of disease activity affect the levels.

Yes, prednisone can absolutely affect lab results used to monitor lupus, which could potentially lead to misleading results. Here's how it can impact key tests:
- Complete Blood Count (CBC) — Prednisone can alter red blood cell and immune cell counts, making results look abnormal or unexpectedly normal
- Autoantibody levels Show Full Answer
Yes, prednisone can absolutely affect lab results used to monitor lupus, which could potentially lead to misleading results. Here's how it can impact key tests:
- Complete Blood Count (CBC) — Prednisone can alter red blood cell and immune cell counts, making results look abnormal or unexpectedly normal
- Autoantibody levels — Prednisone can suppress antibody production overall, including the specific autoantibodies associated with lupus, which could result in a false negative
- ESR (inflammation marker) — By reducing inflammation, prednisone can bring this back to a normal range, masking underlying disease activity This is exactly why doctors typically order baseline blood work *before* starting prednisone. That way, they have a reference point to compare against and can better interpret any changes in results over time.
If there's upcoming lab work while on prednisone, it's really worth flagging that to the ordering doctor beforehand — it can make a big difference in how results are interpreted.
