DRB3/4/5 Recognition Improvements:

  • DRB3 → recognizes all DRB3 alleles (DRB3*01, DRB3*02, DRB3*03, etc.)
  • DRB3*01 → recognizes all DRB3*01 subtypes (DRB3*01:01, DRB3*01:62, etc.)
  • DRB4 and DRB5 → same logic applied
  • Each allele now has its specific frequency instead of combined values
  • Mode differentiation: DR51/DR52/DR53 → fill USG modes, DRB3/DRB4/DRB5 → UA mode only
  • Column renamed: USG+C/DP → USG+C/DP/DQA
  • Interface: automatic field clearing when switching between Single/Batch modes
