immunoassay
C2CEFR level
95/100Rarity: very rare
TechnicalRegister
A test that uses antibody-antigen binding to detect or quantify a target substance.
The immunoassay flagged a possible interference, so the sample was rerun by an alternative method.
Rarity runs from 0 (a word everyone knows) to 100 (almost never seen outside specialist or literary writing). Level is the word's real difficulty on the CEFR scale, from A1 to C2.
