Advice please. My son is 5 and his blood was being monitored as they suspected Systemic Lupus. 4 of his blood tests showed low C4 with regular leg pains and limping occurances, permanantly swollen glands in his neck. Iron deficiency, sudden bed wetting etc. Then after Iron supplements his C4 improved but apparently only slightly low C3. All the other symptoms are still there but because the last blood test showed improvement my son has been dismissed by 'the new doctor' who only saw him that once! I went away and left it but he seems to be going downhill again.
Confused about the blood tests. Does and increased c4 and C3 mean that it isn't lupus? As that is what the doctor told me. She said if its up and down then it is more likely to be the cause of an infection.
