抗体検査 まだ使い物にならない、と

まあ、ちゃんとした検査試薬も確立していないわけだから、いきなり１０分でできる、血液１滴でわかるという類の謳い文句の商品に飛びつかないことですね。そもそも検査は、臨床的意味があるか、感度・特異度はどうか、検査としての安定性は、といった当たり前で普通の点を全てクリアしないといけません

まだまともなコロナウイルスの抗体検査が存在しないとのニュース。未だに、先進各国(G7)のどの国も使い物になる迅速テストを見つけていないし、つくれていないとのこと。 https://t.co/A8FACtcU1s

World leaders say they have so far failed to identify a single coronavirus antibody test which is accurate enough for use

If successful, such tests could allow the roll-out of so-called "immunity passports" allowing people to leave the coronavirus lockdown early.
However, the UK's Health Secretary Matt Hancock revealed that no leading industrial nation has yet identified a test which is accurate enough for use.
"On the G7 call earlier it was clear that no G7 country has found a home antibody test that works," Hancock said.
Spain was recently forced to return thousands of testing kits after they were found to have a 30% detection rate.

英国の出口戦略である「免疫成立証明書」発行の予定は、購入した抗体検査の性能が芳しくない様子。いったん挫折の可能性
＊ここは焦らず、まず抗体量を精密に評価できる定量検査（ELISA）を開発し、それを参照しつつ迅速検査（免疫クロマト法）で性能のよいのを作るべきかhttps://t.co/2PYR4pkqwQ

使い物にならないかもしれないけど、できることはすべてやるとかいって買っちゃった、って言っていたようねえ。

Hancock said work was progressing with the antibody tests but that the results of many of the early tests had been “poor” and he was more hopeful about later ones that have been acquired. The government has bought options on up to 17.5m antibody tests of different types that are currently being tested, but cannot say definitively when they will be safe to use.

When the antibody tests are available, Hancock said, the government was looking at the possibility of issuing immunity certificates, so that some of the population “can get back to work as much as possible”.

However, some critics fear that this could lead to resentment in the population who have not had the virus, and that people might even deliberately try to get infected in order to obtain an immunity certificate.
