Question

Quizplus · Accepted Answer

Cold agglutinin titer testing is primarily used to confirm the presence of atypical pneumonia, which is caused by mycoplasma pneumoniae infection. In this condition, cold agglutinins are produced that cause clumping of red blood cells at low temperatures. The other options, von Willebrand disease, Down syndrome, and Tay-Sachs syndrome, do not involve the production or detection of cold agglutinins.
