• To measure blood pressure

• To determine blood sugar levels

• To check cholesterol levels

Which type of antibodies does the direct Coombs test detect?

• IgA antibodies

• IgG antibodies

• IgE antibodies

• IgM antibodies

What is the result of a positive direct Coombs test?

• Red blood cells change color

• Red blood cells dissolve

• Red blood cells clump together

• No change in red blood cells

What does the indirect Coombs test focus on?

• Detecting antibodies on the surface of red blood cells

• Identifying free-floating antibodies in the serum

• Measuring the size of red blood cells

• Counting the number of white blood cells

In what scenario is the indirect Coombs test particularly useful?

• Measuring blood pressure

• Checking blood before transfusion
