Hello and a blood test question

Hi. What a wonderful board this seems to be. I am 43 year old woman in the USA and I have 5 wonderful kids and a great husband. I may be starting a Lupus journey, but I'm not sure. This is my story. Early in December, I had a bout of illness that progressed like this: Day 1, achy; Days 2 and 3 achy and low grade fever; Day 4 high fever that broke after 5 hours or so and then felt much better; Day 5 fine but slight lacey rash on trunk and extremities that lasted half a day; Day 6 woke up to extremely sore and swollen joints in ankles, knees, wrists and hands which got better with ibuprofen but I was left with an achiness behind both legs; Day 7 everything better but very stiff neck; Day 8 illness gone.

On Day 5 because I was going to a family party I went to my doctors to see if they thought it was ok for me to go and not be contagious. By the time I got there in the afternoon, the rash was gone, so they just told me that they thought it was a fever rash based on what I had told them. If I felt sick again, they told me to come get some bloodwork done.
That was a Friday and it was a Saturday morning that my joints were affected. Because it all subsided with some MOtrin I waited until Monday to call the doctor. At that point though I felt fine, because of the joint involvement, they ran some bloodwork. Also, I'm on Lipitor so they wanted to check out my blood for side effects from that. I believe the ANA came back elevated on that, so they did an anti-ds DNA test and CBC. My plateletts came back slightly low and the anti-ds test came back very high (255)

I was referred to a rheumatologist. He took a good history. I've very rarely been sick in my whole life. He acknowledged that the ds test was high. He also noted from prior blood work done when I was pregnant that I had no antibodies for the parvovirus B19 (Fifth's Disease). He ran more blood work and a complete Lupus screening through the Mayo Clinic and my bloodwork for the parvovirus came back at 3.9 while the normal range is .9 and under. My levels of the anti-ds test fell to 75 and the ANA fell back to near the normal levels. Also my red and white cells were all well within normal range.

I have not felt sick since that week in December. The rheumatologist believes that I had and acute febrile illness brought on by the parvovirus but he could not say that my reaction to the virus was the cause of the positive lupus test. He also felt that my "flare" was short in duration and perhaps indeed, it was more like a virus than Lupus. At this point, because I feel fine and the parvo test was so high and the other levels were dropping, he wants to test me in 3 months and see what happens then. I am happy that he wants to retest and feel comfortable with going that route since I feel fine. From what I've read though, I don't see how the anti-ds DNA test would be elevated and then fall if I didn't have Lupus. On the one hand, maybe I had the parvovirus too and because of the blood work done found out I have Lupus long before any symptoms manifested themselves -- a very lucky happenstance. But on the other, I'm afraid that the doctor won't treat me with Plaquenil since I'm not presenting at present with symptoms of concern. I have 5 kids that I need to see grow up and be there for, so obviously any headstart in managing the disease is desired.

I have done a ton of on-line research (admittedly, I am not a medical professional so that can always be dangerous) and I have not once seen anyone NOT have Lupus with a highly positive anti-ds DNA test.

Sorry this is so long, but as you know just talking about fears and concerns helps to deal with them. Thank you for listening.
