This is David Noah’s results from the ALPS study, taken back in 2010–most of the equations with C3 in it are lower than the ‘reference range’ for the study–

The diagnosis was not consistent with ALPS, but they didn’t write ‘normal’ either–most of the tests that were normal, they just wrote ‘normal’, but this study they did not–

(I’m just wondering if the ‘C3’ they’re talking about in these results, is the same ‘C3’ in the complement articles I’m reading about–)
