The Lutheran b blood antigen is a high prevalence antigen occurring in 99.8% of Caucasians. Consequently, antibody formation against Lutheran b is very rare. While this antibody can cause hemolytic reactions in adults, there is limited clinical information on its effects on the fetus and newborn.

What ethnicity is B negative blood?
This means an approximately 1.5% of the population has a B negative blood. Note however that not all of the ethnic groups share the same proportions of the B negative blood type. This blood type is present in about 2% in Caucasians, 1% in African American, 1% in Hispanic, and 0.4% in Asian. 2. Inheritance Patterns
Who can give blood to B negative?
Learn More About Your Blood Type Compatibility
- About 9% of the population have B positive blood.
- B positive red blood cells can be given to both B positive and AB positive patients.
- B positive patients can receive blood from B positive, B negative, O positive and O negative donors.
What does it mean to have B- negative blood?
The first one is known as Rh+/Rh- blood group system, while the other one is called ABO. People who have B negative blood type are often called as those who have the most precious blood on the planet.
What makes the B positive blood type?
The two important blood group classifications in humans are the ABO and the Rh systems. The ABO system has four major blood groups – A, B, AB, and O. Blood type A has the antigen A, blood type B has the B antigen, and O has no antigen on its surface . Each of these groups is either Rh positive (D) or Rh negative, which means there are eight major blood groups in all.
How rare is Lutheran B negative?
The rare blood group phenotype lacking Lutheran antigens, Lu(a-b-), is known to have two genetic backgrounds. Tests on 250000 blood donors show the frequency of Lu(a-b-) to be approximately 1 in 3000.

The most common Lutheran phenotype is Lu(a−b+), 92.4%, while only 7.4% of the population is Lu(a+b+) (Answer D).
Is Lutheran clinically significant?
Nine blood group systems (ABO, Rhesus, Kell, Kidd, Duffy, MNS, P, Lewis, and Lutheran) are considered to be clinically significant as these are known to cause hemolytic transfusion reactions (HTR) and hemolytic disease of fetus and newborn (HDFN) [1–4].
How rare is B negative blood?
2%Less than 2% of the population have B negative blood. B negative red blood cells can be given to both B and AB patients. B negative patients can only receive blood from other B negative donors or from type O negative donors (who are the universal donors).
Is Lutheran antibody significant?
In the context of transfusion, anti-Lua is rarely clinically significant for most patients. It does not contribute to acute hemolytic transfusion reactions and is very rarely associated with mild, delayed hemolytic transfusion reactions and mild hemolytic disease of the fetus and newborn (HDFN).
What is Lutheran antibody?
Abstract. The Lutheran b blood antigen is a high prevalence antigen occurring in 99.8% of Caucasians. Consequently, antibody formation against Lutheran b is very rare. While this antibody can cause hemolytic reactions in adults, there is limited clinical information on its effects on the fetus and newborn.

How many people have B negative blood?
It is only present in 1 out of 67 individuals. This means an approximately 1.5% of the population has a B negative blood. Note however that not all of the ethnic groups share the same proportions of the B negative blood type. This blood type is present in about 2% in Caucasians, 1% in African American, 1% in Hispanic, and 0.4% in Asian.
What are some examples of blood type B?
It should not be aerobically intense but instead a mixture with mental challenges. Great examples would be hiking, cycling, golf, tennis and martial arts.
What is the ABO gene?
The ABO gene found on chromosome 9 determines the ABO blood group system. A and B genes are codominant in relationship, making the expression of both antigens A and B when either alleles A or B is present. Blood Group B has a B antigen on red cells with the A antibody in the plasma.
What is the second rarest blood type?
1. The Second Rarest Blood Type. Negative blood types are actually rarer compared to positive types. The B Negative blood type is one of the rarest and second to AB Negative, being the rarest of the blood types. Being rare, it is extremely important to maintain sufficient supply for this blood type considering that it’s one ...
How many times can a B+ donor donate blood?
This is because of the presence of antigen B and the absence Rh antigen in the donor’s blood. Male individuals can donate blood for up to 4 times each year while females can have it for up to 3 times a year.
Can B receive AB?
5. Plasma Type Compatibility: B Can Receive B and AB. Blood Type B doesn’t carry the B antibody, making blood type B group to be compatible in receiving plasma from groups B and AB. However, blood type B plasma can only be given to type O and B recipients. 6.

What is the Lutheran blood group system?
The Lutheran blood group system (BGS) consists of a large number of antigens, 24 being recognised by the International Society of Blood Transfusion at the time of writing, and is also of interest in terms of the various backgrounds to the (apparent) Lu (a-b-) phenotypes.
When was the cognate antibody discovered?
The first antigen described within this particular BGS, Lu a, was described briefly by Callender et al in 1945, and in more detail by Callender and Race in 1946. The cognate antibody was discovered in a patient with lupus erythematosus, who also produced the first described anti-C w of the Rh BGS and anti-Kp c of the Kell BGS.
Can Lutheran antibodies cause HTR?
With rare exceptions, and where data is available, Lutheran antibodies cause neither a haemolytic transfusion reaction (HTR), nor haemolytic disease of the foetus and newborn (HDFN).
Is the Lutheran BGS incorrectly named?
The Lutheran BGS is also incorrectly named, as will be explained shortly. There are four antithetical pairs of antigens within the BGS, but certain antigens (for example, Lu10) appear to be missing. This is the result of so-called para-Lutheran antigens, reported as possibly belonging to the Lutheran BGS but later proved to belong elsewhere.
Is Lutheran B a high prevalence antigen?
Abstract. The Lutheran b blood antigen is a high prevalence antigen occurring in 99.8% of Caucasians. Consequently, antibody formation against Lutheran b is very rare. While this antibody can cause hemolytic reactions in adults, there is limited clinical information on its effects on the fetus and newborn. As a high prevalence antigen, it may be ...
Is Lutheran B blood negative?
The Lutheran b blood antigen is a high prevalence antigen occurring in 99.8% of Caucasians. Consequently, antibody formation against Lutheran b is very rare. While this antibody can cause hemolytic reactions in adults, there is limited clinical information on its effects on the fetus and newborn. As a high prevalence antigen, it may be difficult to obtain Lutheran b-negative blood for possible maternal transfusion. We describe two cases of pregnancy complicated by Lutheran b alloimmunization. These cases highlight the potential fetal and maternal complications associated with this antibody and we review options to maximize perinatal outcome.
What would happen if a man donated blood in Switzerland?
It was quicker that way: If the man donated in Switzerland, his blood would be delayed while paperwork was filled out and authorizations sought. The nurse in Annemasse, France, could tell from the label on the blood bag destined for Paris that this blood was pretty unusual.

What time did Francisca's blood fly to Kumbo?
Her blood flew the rest of the way to Kumbo and arrived at 2 p.m., just after Francisca had been wheeled into the operating room.
How many antigens are there in the blood?
On the surface of every one of our red blood cells, we have up to 342 antigens—molecules capable of triggering the production of specialized proteins called antibodies. It is the presence or absence of particular antigens that determines someone’s blood type.
How many blood groups are there in the human body?
There are 35 blood-group systems, organized according to the genes that carry the information to produce the antigens within each system. The majority of the 342 blood-group antigens belong to one of these systems. The Rh system (formerly known as “Rhesus”) is the largest, containing 61 antigens.
