RESUMO
An enzymeimmunoassay (EIA) for H-TSH (human thyrotropin) in dried blood on filter paper using an anti-H-TSH conjugate with ß-D-galactosidase and tubes coated with an anti-H-TSH was performed fo the screening program for detection of congenital hypothyroidism. The blood volume needed in this assay was 8.7 µl. The precision was evaluated by coefficients of variance within and between assays: 11.86 percent and 14.36 percent for H-TSH levels of 18.5 µU/ml and 35 µU/ml. A good correlation was observed between H-TSH concentration measured by EIA and RIA (r=0.91)
