title: [Serological Characteristics and Family Survey of 3 Cases of H-deficient Blood Group].
abstract: OBJECTIVE
  To investigate the serological characteristics and the genetic status of the family of H-deficient blood group in Jining area of Shandong province in China.
  
  
  METHODS
  ABO, H, and Lewis blood groups in 3 probands were screened out by the serological method, and saliva testing was performed on all the individuals. The presence of weak A or B on the RBC was confirmed by using the adsorption-elution procedure.
  
  
  RESULTS
  Three cases of H-deficient blood group were identified to be para-Bombay blood group (secretor), out of 3 cases, 2 cases were Bh, 1 case was Ah, and anti-H or anti-HI antibody was detected in their serum.
  
  
  CONCLUSIONS
  Three cases of H-deficerent blood group are para-Bombay phenotype, among them one proband's parents have been confirmed to be consanguineous relationship.
