Final answer:
Implied consent in phlebotomy is inferred from the patient's action of extending the arm in preparation for blood draw. If a blood sample agglutinates with both anti-A and anti-B antibodies, it indicates a normal response for an AB blood type.
Step-by-step explanation:
When a phlebotomist is preparing to draw blood and the patient extends his arm and turns his head away, this indicates implied consent. Implied consent is a form of consent which is not expressly granted by a person, but rather inferred from a person's actions and the facts and circumstances of a particular situation. In this case, the action of extending the arm suggests that the patient agrees to the procedure.If a patient has blood drawn and the sample agglutinates in both the anti-A and anti-B antibody solutions, this is a normal response for a certain blood type. This indicates that the patient has AB blood type. Agglutination in both well reactions is expected for this result, suggesting that the technician has not made an error in this blood typing procedure.
