Exercise 11: Blood Analysis: Activity 2: Erythrocyte Sedimentation Rate Lab Report
Pre-lab Quiz Results
You scored 100% by answering 3 out of 3 questions correctly.
  1. The erythrocyte sedimentation rate (ESR)
    You correctly answered: c. is increased whenever fibrinogen and immunoglobulins cause the RBCs to clump together, stack
    up, and form a column.
  2. The ESR cannot be used to follow the progression of which of the following diseases?
    You correctly answered: d. gingivitis
  3. The ESR can be used to evaluate a patient with
    You correctly answered: e. all of the above.
Experiment Results
Predict Question:
Predict Question: How will the sedimentation rate for sample 6 (individual with angina pectoris) compare with the
sedimentation rate for sample 1 (healthy individual)?
Your answer : b. It will be lower.
Stop & Think Questions:
What is in the beige-colored portion of the sedimentation tube?
You correctly answered: c. plasma
Experiment Data:
Blood sample Distance RBCs have settled Time elapsed Sedimentation rate
1 5 mm 60 min 5 mm/hr
2 15 mm 60 min 15 mm/hr
3 0 mm 60 min 0 mm/hr
4 30 mm 60 min 30 mm/hr
5 40 mm 60 min 40 mm/hr
6 5 mm 60 min 5 mm/hr
Post-lab Quiz Results
You scored 100% by answering 3 out of 3 questions correctly.
  1. The erythrocyte sedimentation rate (ESR) measures
    You correctly answered: d. the settling of RBCs in a vertical, stationary tube of whole blood during one hour.
  2. An increase in the ESR is
    You correctly answered: c. associated with worsening of anemia.
  3. To properly measure the ESR, you need
    You correctly answered: c. a 1-hour timer.
Review Sheet Results
  1. Describe the effect that sickle cell anemia has on the sedimentation rate (sample 3). Why do you think that it has this
    effect?
    Your answer:
    Sickle cell anemia has no effect on sedimentation rate.
  2. How did the sedimentation rate for the menstruating female (sample 2) compare with the sedimentation rate for the
    healthy individual (sample 1)? Why do you think this occurs?
    Your answer:
    It is elevated due to the hormones being secreted in the menstruating female.
  3. How did the sedimentation rate for the individual with angina pectoris (sample 6) compare with the sedimentation rate
    for the healthy individual (sample 1)? Why? How well did the results compare with your prediction?
    Your answer:
    It is same which incorrect with my prediction.
  4. What effect does iron-deficiency anemia (sample 4) have on the sedimentation rate?
    Your answer:
    When I check results, it increase sedimentation rate.
  5. Compare the sedimentation rate for the individual suffering a myocardial infarction (sample 5) with the sedimentation
    rate for the individual with angina pectoris (sample 6). Explain how you might use this data to monitor heart conditions.
    Your answer:
    We can use this date to find out the person with a myocardial infarction, because the person with a myocardial infarction has
    significantly high rate of sedimentation.
