Article Synopsis
- The expression of ABO (ABH) antigens on red blood cells and the secretion of ABH substances in bodily fluids are controlled by different genes, with the Secretor gene determining secretor status.
- A study conducted on 318 blood donors in South India from Jan 2020 to Dec 2021 found that 72% were secretors while 28% were nonsecretors, revealing a clear relationship between secretor status and Lewis phenotyping.
- The findings suggest that knowing the Lewis phenotype can help identify blood group secretor status, which is crucial for resolving discrepancies in ABO blood groups in medical settings.
The P blood group system was introduced in 1927 by Landsteiner and Levine. About 75% of the population possesses P1 phenotype. P2 simply implies P1 negative and there is no P2 antigen.
