ANA – antinuclear antibodies, CRP – C-reactive protein, ESR – erythrocyte sedimentation rate, LDG – lactate dehydrogenase, RF – rheumatoid factor. In the table the highest levels of parameters are presented: na – not available, doubtful – 14.2 IU/ml in the first test, all other determinations < 10 IU/ml.
