- What percentage of the type A population is A2?
- What other consideration should be made before beginning a subgroup investigation?
- If a group O mother gives birth to a group A baby, which of the following antibodies is usually responsible for crossing the placenta and causing hemolytic disease of the newborn (HDN)?
- All of the following may result in weak or missing antigens except:
- What immunodominant sugar is responsible for H specificity?
- When performing secretor studies, what is omitted in the control tube but present in the patient tube?
- What substances are found in a group A secretor?
- Secretor studies were performed on a person who expressed weak reactions in forward grouping. Only B and H substance were present in the saliva. What is this person's ABO group?
- What is the biochemical structure of secreted A, B, and H substances?
- Serum from a group B individual contains anti-A. When A2 cells are added to serum and centrifuged, the cells with attached anti-A are removed from serum. What is the name of this technique?
- Which of the following is not characteristic of antibodies within the ABO system?
- Which ABO group's reaction will be the weakest with anti-H lectin?
- Two drops of serum are added to one drop of A1 cells, and two drop s are added to one drop of B cells; the two tubes are centrifuged. The tubes show reactivity when read macroscopically. This is an example of:
- A group O person with warm autoimmune hemolytic anemia may demonstrate weak reactions in the forward grouping due to:
- Where will the ABO discrepancy occur in cis-AB individuals?
- ¿Qué pasa con la cámara y el teléfono de Peter en la jungla?
- What ABO group contains the least amount of H substance?
- ¿Qué comida come Peter en Cartagena?
- Cord blood was sent to the laboratory for blood type determination on twins A and B. Baby A demonstrated mixed-field reactions with anti-A and anti-AB and no reactivity with anti-B. Reverse grouping was not performed. Baby B showed a 1+ reaction with anti-A and anti-AB. What could be the reason for the variable reactions?
- Approximately how many antigen sites exist on a type-A1 individual's RBC?
