化學中兩個用詞 中文是什麼?

句子: It is possible to get a false-positive or a false- negative result when testing for ions.

Propose a situation that could lead to a false positive for a particular ion. Choose a different ion and show how a false negative could result. Which do you think is more likely to happen? Explain.

    偽陰性false-nagative:有過危險性行為的人若在空窗期之內接受愛滋病毒檢驗,即使呈陰性反應(未被感染),這個檢驗結果也不可靠,此即偽陰性。

    偽陽性false positive:目前的檢驗方法敏感度非常高,有可能因其他病毒而產生陽性反應,這只是試劑過度敏感,不一定表示真的受到感染,此即偽陽性。若您的檢驗報告請您回去複檢,請勿過於慌張,記得回同一家醫療院所進行另一種檢驗即可!

    A false-negative test result is one that does not detect what is being tested even though it is present. A false-negative test result may thus suggest that a person does not have a disease or condition being tested for when in fact he or she does.

    For example, a false-negative pregnancy test result would be one that does not detect the substance (human chorionic gonadotropin) that would confirm pregnancy, when in reality the woman is pregnant.

    通常此兩個名詞用在生物學比較多.特別是孕婦那方面的 化學比較少用 剪下一篇文章跟你分享
