Hi There~ Here I am again I posted back in May which feels like moons ago. Since then I have switched Dr's (rhuem) which is looking like to be a good choice. I do have a + ANA not sure of the # and have been diagnosed with APS. My completement C4 came back low as well. My next appt is Monday I just went for a pulmonary function test this past Tuesday not sure how that went I'm sure I will know on Monday. My new Rhuem is concerned with my hematacrit, Hemoglobin and RBC they are all high and have been high for years she's the only one who is actually investigating it. Possibly she will send me to hemotolgist. She also said it's looking like lupus but's its such a large umbrella. I have been on baby asprin and 400mg of plaquinel for 5 months now. Just thoguht I'd say Hi as I have been reading a lot of info here.
