... Rebeccajane, just want to say hi and welcome. I saw recent news articles suggesting that anti-chromatin AB is now being viewed as a significant finding in lupus with kidney involvement. This "take" looks recent to me.
You can view the criteria "most used" to diagnose SLE in one of the sticky posts (permanent info posts) located above the thread list. In those, the... (9 replies)

... Hi & welcome. I think the antibody tests are often parsed into ranges confusing to newcomers. (They were to me, anyway!) Sometimes you'll see ranges for "negative", for "low-positive", "positive", and "high-positive". I suspect that doctors generally hold off on looking for lupus if ANA is in the negative range, unless symptoms & other labs very strongly point that way.
But... (1 replies)

... Lori, Where lupus is a possibility, I think elevated B.U.N. and creatine in bloodwork are signs kidneys aren't filtering properly. (I just reread your original post & realized you said those values were NOT QUITE out of range.) And urinalysis includes checks for "urine casts" and for protein in the urine, which are also signs of abnormal kidney function.

... I remember having a blood test done a while ago when I was being worked up for something else, and the test said something about being positive for anti ds-DNA ase, and I know this is an antinuclear antibody, but does it mean that I'm going to get lupus at some time in my life? Or does it just mean that I had inflammation or something? My aunt has lupus, scleroderma, and... (1 replies)
... Melissa, very *high* anti-ds-DNA points strongly to lupus, but *slight* elevations are possible in some other conditions. In fact, a very high finding would fulfill one of the 11 ACR criteria. But without the reference range, it's impossible to tell how high yours is; so when you discuss your findings with your doctor, you should ask for the range & ask how high he/she deems... (5 replies)
... Hi. Do you have hardcopy of the labs, or were results read over the phone? My lab prints out-of-range vs. in-range values in separate columns.
For anti-ds-DNA, my lab uses these ranges, BUT there's no guarantee your lab uses the same. For something this important, I'd ask the doctor for hardcopy.
< 25, Negative;
35-99.9, Weakly Positive;
100-200,... (2 replies)

... Hi. Apparently anti-ds-DNA can vacillate: it can be higher just before, or at the start of, flares; and once it turns positive, it stays positive. I don't know that it's a titer test, though (sorry), you'd have to ask. Unfortunately, if the reference range on the report says >10 is positive, then >20 appears to be solidly positive, but you should confirm with someone familiar... (3 replies)

... Thanks for your input VeeJ. The followup with my GP is open. It's pretty much up to me. I can see him on fairly short notice. Since I posted my message I have done some reading and I see that many rheumie's diagnose a patient with Lupus based solely on the anti-ds-DNA. Makes sense if it is very selective and it is so hard to make a diagnosis otherwise anyway. I'll discuss this... (3 replies)

... Destiny, hi.
Your first question: I think there are two different measuring systems for ANA. (1) The first is a simple ratio, like the 1:40 you mentioned. I *think* some experts consider 1:30 (and above) to be high. (2) In the second measuring system, the number doubles for each dilution. Examples: 1:80, 1:160, 1:320, 1:640, 1:1280, etc. I *think* some experts... (3 replies)

... On my last bloodwork, the results were back to my doctor's office within a week.
On my lab work, the normal reading for anti-DS-DNA was 0-4 and mine came back at 47.
Good luck with everything and let us know how your results turn out.
