Final answer:
In the presence of a hemolytic process due to G6PD deficiency, the direct antiglobulin test is usually negative.
Step-by-step explanation:
A direct antiglobulin test (also known as a Coombs' test) is used to detect antibodies or complement proteins bound to the surface of red blood cells. In a hemolytic process, such as autoimmune hemolytic anemia or transfusion reactions, the direct antiglobulin test is typically positive. However, in the presence of a hemolytic process due to glucose-6-phosphate dehydrogenase (G6PD) deficiency, the direct antiglobulin test is usually negative. This is because the hemolysis in G6PD deficiency is not immune-mediated.
