To assess how EIA results would agree with those by the gold standard method of plaque reduction neutralization (PRN) we compared the results from the two methods in 43 pairs of maternal and umbilical cord sera, and sera from the corresponding infants when aged 11 - 14 months. In maternal-cord sera, the differences between mean antibody levels by EIA or PRN were not statistically significant, though in individual sera, differences could be large. However, agreement was less good for infants sera, in which levels of mIgG were very low. The conclusions of a study of transplacental transport of mIgG would not be affected by the use of either technique. When studying waning immunity in infants, PRN should be the method of choice, while results from studies using EIA should be interpreted with caution.<\/jats:p>","DOI":"10.1590\/s0036-46651999000100005","type":"journal-article","created":{"date-parts":[[2005,4,27]],"date-time":"2005-04-27T13:26:27Z","timestamp":1114608387000},"page":"21-26","source":"Crossref","is-referenced-by-count":9,"title":["COMPARISON OF A COMMERCIAL ENZYME IMMUNOASSAY WITH PLAQUE REDUCTION NEUTRALIZATION FOR MATERNAL AND INFANT MEASLES ANTIBODY MEASUREMENT"],"prefix":"10.1590","volume":"41","author":[{"given":"Guilherme","family":"GON\u00c7ALVES","sequence":"first","affiliation":[{"name":"Instituto Nacional de Sa\u00fade Dr Ricardo Jorge, Portugal"}]},{"given":"Felicity","family":"CUTTS","sequence":"additional","affiliation":[{"name":"London School of Hygiene and Tropical Medicine, UK"}]},{"given":"Timothy","family":"FORSEY","sequence":"additional","affiliation":[{"name":"National Institute for Biological Standards and Control"}]},{"given":"Helena Rebelo","family":"ANDRADE","sequence":"additional","affiliation":[{"name":"Instituto Nacional de Sa\u00fade Dr Ricardo Jorge, Portugal"}]}],"member":"530","reference":[{"key":"ref1","doi-asserted-by":"crossref","first-page":"251","DOI":"10.1016\/0166-0934(81)90062-8","article-title":"Role of virus strain in conventional and enhanced measles plaque neutralization test","volume":"3","author":"ALBRECHT P.","year":"1981","journal-title":"J. virol.
