Answer:
The correct answer is option d. "Polyclonal antibodies".
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is very useful in comparison to other immunoassay methods for being highly accurate, sensitive and specific. Polyclonal antibodies for the detection step could be used on order to ensure that a mutation in a single surface protein would not make obsolete an ELISA used to detect a new viral pathogen. Unlike monoclonal antibodies, polyclonal antibodies are a collection of antibodies that recognize multiple epitopes of the same antigen. Therefore, a mutation in one epitope that affects the binding of one antibody would not affect the bind of the others and the ELISA will be able to recognize the pathogen.
60 seconds
To ensure that all bacteria are removed from the puncture site for blood cultures, the site should be cleansed using friction for a minimum of 60 seconds.
<h3>Where exactly is the puncture site?</h3>
- The proper location must be cleansed and punctured with a lancet so that a drop of blood can be softly expressed before blood can be collected using a capillary tube.
<h3>But what constitutes a
suitable location? </h3>
- Finger: In both adults and children, the third or fourth finger is typically favored location as a puncture site
<h3>Where on the body does a skin puncture most frequently occur?</h3>
- The most frequently used site is the distal end of the third or fourth finger.
- Because the bone is so close to the skin surface, there is a higher risk of puncturing the bone at the very tip of the finger.
