Re: Positive ANA: What does this mean?
Hi. One author considers 1:1280 a high ANA reading, but I don't think you should ignore an ANA elevation when accompanied by symptoms. One reason is that levels can rise & fall as flares come & go, so 1:160 wasn't necessarily a "peak reading"... plus it could elevate further over time. Another reason is that the ANA test is difficult to perform, and not all labs are too good at it.
Also, ANA is only a general test. Because it's positive in a variety of conditions, by itself it can't diagnose anything. A rheumatologist would probably run more tests to look for SPECIFIC autoantibodies.
Vitamin D is often depressed in inflammatory conditions. (Mine was.)
I think Hashimoto's thyroiditis (which is autoimmune) alone can elevate ANA. Is your hypothyroidism of that particular subtype? But even if it is, because Hashimoto's can occur *in conjunction with* other autoimmunes, I agree with the suggestion to see a rheumatologist, to evaluate you for a possible second condition.
Have you seen the "sticky posts" at the top of the thread list? They contain info on tests, criteria, symptoms, further reading, etc. Let us know how you're doing, OK? Sending warm wishes, Vee
