美國西奈山伊坎醫學院Florian Krammer團隊開發了血清學分析來檢測人類中新冠病毒的血清轉換。相關論文於2020年5月11日在線發表在《自然—醫學》雜誌上。
研究人員利用血清酶聯免疫吸附測定來篩選和鑑定了人類SARS-CoV-2血清轉化。該測定不需要處理傳染性病毒,可以調整來檢測血清和血漿中的不同抗體類型,並且可以按比例縮放。
血清學檢測對於幫助確定人群中暴露過SARS-CoV-2的風險,確定用於恢復性血漿療法的高反應性人類供體以及研究保護相關性至關重要。

Abstract: Here, we describe a serological enzyme-linked immunosorbent assay for the screening and identification of human SARS-CoV-2 seroconverters. This assay does not require the handling of infectious virus, can be adjusted to detect different antibody types in serum and plasma and is amenable to scaling. Serological assays are of critical importance to help define previous exposure to SARS-CoV-2 in populations, identify highly reactive human donors for convalescent plasma therapy and investigate correlates of protection.
