- Individuals with group B blood are more common among which populations?
- An AB males mates with an AB female. What could be the genotype of the offspring?
- The forward group of a patient showed no agglutination of patient cells with anti-A, anti-B, or anti-AB reagent antisera. The reverse grouping showed agglutination with A1 and B cells. What is this person's ABO group?
- A patient was previously typed as a blood group O. Forward grouping was negative with anti-A and anti-B. Reverse group showed reactivity with A1 cells and B cells. The technologist reported this patient's type as A. What technical error occurred?
- All of the following are technical errors that could result in ABO discrepancies except:
- What is used to stimulate saliva secretion in secretor studies?
- If a type-A person contains anti-M in their serum, what might their reverse grouping type as?
- The state in which an individual's red blood cells are agglutinated by all sera regardless of blood type is called:
- Which blood group contains the highest concentration of H antigen?
- A type-A person demonstrates a 3+ reactivity with A1 cells (reverse grouping). The forward grouping with anti-A is 4+. Therefore, the possibility of a subgroup is excluded. B cells demonstrate a 4+ reaction. The antibody screen is weakly positive at 37C, but shows no reactivity at the AHG phase. An antibody panel is performed and anti-M is identified. The patient phenotypes negative for M antigen. How is the ABO discrepancy resolved?
- What percentage of A2 individuals produce anti-A1?
- Mixed-field agglutination encountered in ABO forward grouping may be caused by:
- Reverse grouping showed negative reactions with A1 and B cells. Forward grouping showed positive reactions with A, B, and AB antisera. What blood type is consistent with these results?
- ¿Cuántos goles mete Enrique en diez minutos?
- Approximately how many antigen sites can be found on A2 cells?
- What percentage of the white population has type-O blood?
- An elderly patient is document as being type O. The forward grouping is negative with anti-A and anti-B. The reverse grouping shows no reactivity with A1 cells and B cells. What can be done to correct the discrepancy?
- What is the only possible phenotype of an offspring produced from two group O parents?
- All of the following may result in weak or missing antigens except:
- What percentage of the type A population is A2?
