Remarks:
Remarkable differences are observed between different methods used for the determination of the
Anticardiolipin IgG antibodies. This results also in a heterogeneous pattern in the classification of this
sample. About 23% classified the sample as negative, while the other participants showed a wide variation
in the classification from borderline to high positive.
