Rapid Microbial Testing

Question 1

Immuno=basey assays

Answer 1

Tests that utilize products of the immune system to detect the presence of a substance via a protein (antigen/antibody)

Question 2

How does the Group-A Strep Test work?

Answer 2

The strip has anti-GAS antibodies on one end (with a dye), which will change colors when Strep A antigens bind with the strip.

Question 3

What does the control region of the Strep Test have?

Answer 3

Fixed antibodies that will bind to dye-labeled antibodies regardless if they are bound to a specific region

Question 4

What does the control region of the strep test being higher than the test region ensure?

Answer 4

It ensures that both samples have fully travelled across the test region and the antibodies used in the test region haven’t been destroyed

Question 5

If a strep test strip doesn’t have the top control line, is it valid?

Answer 5

No

Question 6

How does the rapid Staph test work?

Answer 6

the latex beads agglutinate when a specific antigen is present

Question 7

What does a positive rapid staph test look like?

Answer 7

The test region is agglutinated, and the Negative Control region is NOT agglutinated
