The SLE-Latex is a rapid agglutination test for the direct detection and semiquantification in slide of anti-deoxyribonucleoprotein (anti-DNP) antibodies present in human serum. The determination is made by assaying a suspension of latex particles coated with deoxyribonucleoprotein (DNP) against problem sera. The presence or absence of visible agglutination is indicative of the presence or absence of anti-DNP antibodies in the tested samples.
