A patient parks her bicycle at the front and walks into the lab for a regularly scheduled checkup. You draw here blood, perform a complete blood count (CBC), and notice irregularly high neutrophil counts + low lymphocyte counts. She as no elevated blood pressure, no fever, and no other symptoms of infection. You decide to perform a nose swab for COVID-19 and culture a throat swab to look for the presence of any hemolytic bacteria. Just as an extra precaution, you even perform a chest x-ray. All results are negative. What is likely the cause of her irregular blood cell counts? A COVID-19 B Group A Strep (Strep throat) Pneumonia Allergies Exercise

**Case Study: Irregular Blood Cell Counts in a Routine Checkup** A patient arrives for her regularly scheduled checkup at the lab, traveling by bicycle. During the examination, blood is drawn, and a complete blood count (CBC) is performed. The results show irregularly high neutrophil counts and low lymphocyte counts. The patient does not exhibit elevated blood pressure, fever, or other symptoms of infection. To ensure a comprehensive evaluation, a nose swab for COVID-19 and a throat swab for hemolytic bacteria are conducted, along with a chest x-ray. All tests return negative results. **Question:** Given the circumstances, what is likely the cause of her irregular blood cell counts? **Options:** - **A)** COVID-19 - **B)** Group A Strep (Strep throat) - **C)** Pneumonia - **D)** Allergies - **E)** Exercise **Explanation**: The scenario described suggests considering potential causes of elevated neutrophils and decreased lymphocytes. Based on the information provided and the negative test results for infections, the most plausible explanation could relate to physical activity, such as **Exercise (E)**, which can temporarily alter blood cell counts.
