A member asked:

Is it possible for high dose of cetirizine or ranitodine to cause false neg. ana results? or perhaps prednisone, singulair, (montelukast) puffers or nsaids? thanks

Not likely: These medications should not effect ANA level on lab results.

Prednisone may: when taken in very high doses for a long time but not the others.
