ALB and systemic lupus erythematosus: Interestingly, SLE patients (n = 8) tended to have more albumin (HSA)-IgG immune complexes than healthy controls (n = 8), but had not significantly increased overall levels of albumin (HSA)-IgG complexes compared to matched controls (Figure 2C, p = 0.25), not even after normalization for either the peak IgG value, or the peak HSA value or both (data not shown).
