My C3,C4 and CBC w/Differential
lupie1997 posted:
My C3 was 97.6 and my C4 was 17.7 both on the lower normal side. I went in to the dermatologist and he ordered a lupus panel, due to hair loss, lesions, mouth sores, joint pain, muscle pain, photo sensitivity, eye damage, and more. The Differential shows so far 6 abnormal tests WBC was above the 3.4 to 10.5, it was 11.8 my MCV was 102.3, above 82.0to 98.0, MCH was above the normal of 27.0 to 33.0, it was 33.6, the Neutrophils Relative was above normal at 79.3, normal range 45.0-75.0, Lymphocytes Relative, this was lower than normal at 14.2, normal range 17.0 to 43.0 and the Neutrophils Absolute was higher than normal at 9.36, normal range 1.60 to 6.50. My A.N.A is not showing on here, but my platelets show 229, and the normal range is showing to be 150-450. I don't know what all this means, and I don't have a visit with my doctor for several weeks. Should I be concerned?
