Charcot-Leyden crystals in stool may be associated with an immune response and are thought to be the breakdown products of:
The risk of HbS polymerization is enhanced by a low (acid) pH, a state of dehydration, and increased levels of
2,3-DPG. Increased temperature (above 37°C) also adds to the risk.
Hematology
Which group of conditions INCREASES the risk of HbS polymerization?
Hybridization is a technique used to determine presence of target DNA or RNA by adding a synthetic strand that binds by complementary base pairing to the target.
Microbiology
In molecular diagnostic testing, hybridization employs complementary base pair binding of a synthetic strand to DNA or RNA.
Transfusion of red cells of any ABO type other than O to a group O patient is of course likely to cause a hemolytic transfusion reaction.
