TEST REAGENT WITH IMPROVED SPECIFICITY BY SUPPRESSING FALSE NEGATIVES
This invention relates to a specimen-extracting solution containing a component capable of strongly suppressing false negatives, which could not be suppressed by conventional techniques, a method for extracting specimens, and a test reagent using such specimen-extracting solution and such method, when detecting virus, bacteria, target protein, or other antigens from specimens derived from body fluids, such as nasal swab specimens, nasal aspirate specimens, nasal wash specimens, nasal secretion specimens collected by nose blowing, pharyngeal swab specimens, saliva specimens, fecal specimens, serum specimens, plasma specimens, and urine specimens, with the use of a detection reagent utilizing the antigen-antibody reactions or the reactions between substances interactive with each other. The specimen-extracting solution as a constitutional unit of the test reagent or a member brought into contact with the specimens in a step performed before the detection reaction or a step performed simultaneously with the detection reaction is supplemented with a water-soluble compound comprising a phenyl, benzyl, tolyl, or xylyl group and, bound thereto, at least a carboxyl group, a functional group comprising methylated/ethylated atoms thereof, or a hydroxyl group.
