Lewis Blood Group Test

The Lewis test is for secretor/non-secretor status.

The results can be either:

  • Lea+ Leb- (non-secretor),
  • Lea- Leb+ (secretor), or
  • Lea- Leb- (Lewis negative)

About 5% of people are Lewis negative, these people can't find their secretor status with the Lewis test, they should use a saliva test or DNA test.

Secretor status is used for following the blood group diet at an advanced level, as in the book Live Right 4 Your Type, or to calculate your GenoType in The GenoType Diet: Change Your Genetic Destiny.
