New test to detect carriers of gene for cystic fibrosis [news].

Development of a new test to detect carriers of the gene for 
cystic fibrosis was announced. The test involves the interaction between red 
blood cells from a mouse and a small amount of a 
person's blood serum. The gene for cystic fibrosis is associated with 
a lectin, a factor in the person's blood serum that acts 
to agglutinate (or cluster) the red blood cells of the mouse.
