Answer: For detection and confirmation of HIV antibodies in blood samples.
Explanation: As the name implies ELISA( Enzyme-linked immunosorbent assay) is the first test widely used for determining the presence of HIV in a person's serum because of its high sensitivity. In an ELISA, a person's serum is diluted 400 times and applied to a plate to which HIV antigens are attached. If antibodies to HIV are present in the serum, they may bind to these HIV antigens. The plate is then washed to remove all other components of the serum. A specially prepared "secondary antibody" (an antibody that binds to other antibodies) is then applied to the plate, followed by another wash. This secondary antibody is chemically linked in advance to an enzyme.
Thus, the plate will contain enzyme in proportion to the amount of secondary antibody bound to the plate. A substrate for the enzyme is applied, and catalysis by the enzyme leads to a change in color or fluorescence. ELISA results are reported as a number; the most controversial aspect of this test is determining the "cut-off" point between a positive and a negative result. A cut-off point may be determined by comparing it with a known standard. Unknown samples that generate a stronger signal than the known or control sample or are called "positive" while those that generate weaker signal are "negative".

Answer:
b) Dementia
Explanation:
Pernicious anemia is a type of autoimmune disorder in which there is a reduction or inhibition of the intrinsic factor responsible for the synthesis of vitamin B12 in the intestine. This disease is mainly caused by stomach wall atrophy or other disorders that prevent the correct production of glycoprotein called intrinsic factor.
Despite being associated with possible gastric alterations, pernicious anemia does not always present symptoms, or presents symptoms that may be associated with other diseases, which may make its diagnosis difficult. The most recurrent symptoms may include weakness, malaise, dementia, headaches, and memory and concentration disorders. Dementia is a symptom that can be confused with another condition in older adults.
