What blood type lacks A and B antigens?

Blood group O has no antigens, but both anti-A and anti-B antibodies in the plasma, as well as some special “anti-A,B” antibodies. Blood group AB has both A and B antigens, but no antibodies. Blood group B has B antigens with anti-A antibodies in the plasma.

What blood types are secretors?

If you’re a secretor, it means that your ABO blood type (A, B, AB, or O) is not only in your blood, but also in other body fluids like saliva and mucus. Whether you’re a secretor or not is caused by one particular gene, which you can figure out with DNA testing kits.

What is are the clinical significance of those who are non secretors?

Secretor status of a person can be quite useful to determine certain doubtful cases of ABO blood grouping and also has clinical significance. Non secretors are more prone to different varieties of auto-immune diseases and TTIs infections. Alcoholism has been associated with the Non-secretor blood type.

What blood type has A and B agglutination?

Type O blood contains both anti-A and anti-B antibodies. So, for example, if agglutination occurs when your serum is mixed with type B blood cells, you have type A blood.

How do you know if your blood type is A secretor?

In simple terms, a person is said to be a secretor if he or she secretes their blood type antigens into their body fluids like the saliva, the mucus, whereas on the other hand, a Non-secretor does not put or if so at all very little of their blood type antigens into these fluids [5].

What blood type is the rarest blood type?

What’s the rarest blood type? AB negative is the rarest of the eight main blood types – just 1% of our donors have it.

How do I know if I am a secretor or non secretor?

What substances are found in a Group A secretor?

Definition: The term secretor, as used in blood banking, refers to secretion of ABH antigens in fluids such as saliva, sweat, tears, semen, and serum.

What blood type has no agglutination?

Type O Negative (right) has none of the antigens (A, B or Rh) on its membrane. Agglutination (clumping) of type A red blood cells (RBCs) by anti-A antibodies.

Where do non-secretors not secrete ABO antigens?

Non-secretors do not secrete ABO antigens in their mucous membranes. This includes their saliva and the intestinal lining. Not having protective antigens can lead to autoimmunity. Each blood type has specific ABO molecules on the surface of their cells that only people with that same blood type have.

Which is the gene for secretors and non secretors?

The gene is designated as (Se) for Secretors and (se) for Non-secretors and it is entirely independent of the blood type A, B, AB or O. The individuals secreting antigens in the body fluid are designated as ‘ABH secretors’ in blood banks.

What does it mean to be an ABH secretor?

The term “ABH secretor,” as used in blood banking, refers to secretion of ABO blood group antigens in fluids such as saliva, sweat, tears, semen, and serum. If people are ABH secretors, they will secrete antigens according to their blood groups.

How are blood group antigens secreted into the body?

SECRETOR AND NON-SECRETOR. A person secreting blood group antigens into the body fluids and other secretions like saliva, semen, tear, mucous in the digestive tract and respiratory cavities are named as secretors. In similar terms they put their blood type antigens in the body fluids.
