SECRETOR SALIVA TEST
Postage to laboratory not included.
A person can be either a secretor or a non-secretor. This is
completely independent of whether your blood type is A, B, AB or O. In a
simplified sense, a secretor is defined as a person who secretes their blood
type antigens into body fluids and secretions like the saliva in your mouth, the
mucus in your digestive tract and respiratory cavities, etc. A non-secretor on
the other hand puts little to none of their blood type into these same fluids.
Many metabolic traits, such as carbohydrate intolerance, and immune
susceptibilities are linked genetically to secretor subtype.
With respect to the ABO blood types, it is very difficult to
state that one type is more advantageous than another. Each blood type has its
own strengths and characteristic weaknesses. However, this does not appear to be
the case with the Secretor gene. As a generality, being a Non-secretor (based on
all of the available information) does actually appear to be a potential health
disadvantage. At a very basic level, being able to secrete blood type into your
saliva, mucus, etc. allows for an added degree of protection against the
environment, particularly with respect to microorganisms and lectins.
An additional advantage of being a Secretor might be a
generalized tendency to promote a stabilized, blood-type friendly intestinal
bacterial ecosystem. Many of the friendly (probiotic) bacteria in your digestive
system actually use your blood type as one of their preferential foods. Since
Secretors have a steady supply of blood type in the mucus that lines the
digestive tract, their bacteria have a much more constant food
