Detection of Del Phenotype in RHD-negative blood using heat elution technique and sequence specific primerpolymerase chain reaction / Nor Elizatul Izzati Maswan
DEL is the weakest RhD-positive phenotype that commonly mistyped as RhDnegative. It may induce alloimmunization when transfused to RhD-negative recipients. Serologically, it can only be detected via adsorption-elution test. In Malaysia, few data exist regarding DEL phenotype. The objective of this s...

DEL is the weakest RhD-positive phenotype that commonly mistyped as RhDnegative. It may induce alloimmunization when transfused to RhD-negative recipients.
