External Quality Assessment of Serum Alpha-Fetoprotein Assays
Annals of Clinical Biochemistry: International Journal of Laboratory Medicine, 1980Adequate control of performance in immunoassays of maternal serum alpha-fetoprotein is an essential part of screening for neural tube defects. Information derived from external quality assessment schemes may be of limited value in monitoring individual laboratory performance and stresses the need for proper internal quality control.

External Quality Assessment Schemes for Immunoassays
1981Radioimmunoassays (RIAs) are complex and expensive procedures, yet when properly performed they yield information which has much greater clinical value than most of the simpler analyses in clinical chemistry. Thus, assays of T3, T4 and TSH together provide a very precise measure of the status of the pituitary—thyroid axis; in so doing, they replace ...
