title: [Determination of alpha-1-fetoprotein in maternal serum dried on filter paper by an enzyme immunoassay].
abstract: The suitability of different carrier materials for absorption of serum was investigated with respect to a centralised screening for AFP serum levels in pregnant women, which needs a transmission of the samples. AFP was quantified in an indirect two-site binding enzyme immunoassay. AFP concentrations of native serum and of the eluate from the samples dried on filter paper were in a good agreement with a coefficient of correlation of 0.902. But storage of dried serum samples should not exceed one week because a two week storage diminished the coefficient of correlation to 0.766 and AFP concentrations of paper dried samples were overestimated.
