test results....

This is what I found on the Internet:

Factors that can interfere with your test and the accuracy of the results include:
Medications, such as hydralazine (Apresoline), procainamide (Procan, Pronestyl, Promine), and certain anticonvulsants (such as Dilantin, Mysoline). These medications can cause a form of systemic lupus erythematosus (SLE) called drug-induced lupus. Lupus resulting from these medications may cause a high antinuclear antibody (ANA) titer.
Medications, such as antibiotics (isoniazid, penicillin, and tetracycline), birth control pills, lithium, and some diuretics, such as chlorthalidone (Hygroton).
Heart or blood pressure medications, such as acebutolol (Sectral), captopril (Capoten), atenolol (Tenormin), metoprolol (Lopressor), lovastatin (Mevacor), and quinidine.
Aging. Some older adults (5% to 40%) may have mildly elevated levels. Older women appear to have higher ANA titers than older men.
Steroids, which may cause a false-negative result.

Here is the website where I found the info: answers.yahoo.com/question/index?qid=20061004144943AAGc17E

Here is another website that explains the ANA test: www.labtestsonline.org/understanding/analytes/ana/test.html

I hope this helps! Take care

KaAl . . . I don't remember the blood work . . . but the doctor can tell by certain bloodwork if it is drug induced. Sorry I don't recall where I learned that. Bottom line . . . your doctor would/should pick up on the fact that its drug induced - if it really is. If you ask your doctor, he/she can reassure you either way. Blessings!
