This portion of the lab will consist of two lab group members performing individual finger pricks to draw blood and mixing the blood together to observe antigen and antibody reactions. Universal precautions will be observed and demonstrated by all students during this procedure. 2. Gather the appropriate equipment for this portion of the lab: Lancet for each individual performing the finger prick, a microscope slide, a toothpick, alcohol wipes, and Band-Aids. 3. Following the finger prick procedure from Module 01 Laboratory assignment, each individual should provide one drop of blood on the microscope slide. Try to get the drops of blood close to one another but without touching. 4. Another member will mix the two blood drops together with the toothpick and record any observations you see. There might be the random chance that each group member that provided the blood drop may have the same exact blood type, so it may have to be performed by a few different individuals. 5. Record any observations you see below: O neg & O positive: Formed cells, present on edges, obliterated cells may have been caused by excess agitation. A neg & A positive: Cells obliterated Post-Lab Evaluation Questions The post lab evaluation questions must be completed prior to your submission of the lab. Answers for these questions will be derived from the lab protocol, the weekly concepts associated with the lab and possibly research content from the book and/or online resources. Please cite your work for any reference source you utilize in answering these questions. 1. What did you learn or gain from the presentations you worked on in your group and/or from the other groups presenting about the specific topics?

The perception of the same process is different in every individual. There are many ways to say the same thing. 2. A lot of individuals get the influenza vaccine each year, but it is highly recommended for the young and elderly. Why is this the case? Why do some people who get the influenza vaccine still come down with the flu? The young and old are encouraged to get the flu vaccine because these populations are more susceptible to illness due to either their developing immune system or their declining immune system respectively. The flu vaccine is merely a guess at what this year’s influenza may look like, and on its best year only 40-60% effective (Influenza, 2018). 3. Why isn’t there a vaccine for the common cold but one for chicken pox virus (Varicella Zoster vaccine)? The common cold is difficult to vaccinate against due to its antigenic variability. Since the common cold does not pose a life threat in the typical patient, the uncertainty of vaccinations does not outweigh the risks (Simancas-Racines, 2013). Varicella Zoster is a more serious, potentially life threatening disease that has an established vaccine with limited risks.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
