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 eosinophil count. She as no elevated blood pressure and no fever. 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 counts? A Pneumonia в COVID-19 Group A Strep (Strep throat) D Allergies E Exercise

**Case Study: Diagnosing Irregular Blood Counts**

*Scenario:*
A patient arrives for a routine checkup. After parking her bicycle, she enters the lab where a Complete Blood Count (CBC) is performed. The test reveals an unusually high eosinophil count. The patient does not exhibit elevated blood pressure or fever.

*Investigations performed:*
- **Nose Swab for COVID-19:** Negative
- **Throat Swab for Hemolytic Bacteria:** Negative
- **Chest X-ray:** Negative

*Question:*
What is likely the cause of her irregular blood counts?

*Options:*
- A) Pneumonia
- B) COVID-19
- C) Group A Strep (Strep throat)
- D) Allergies
- E) Exercise

**Analysis:**
This case involves a female patient with a high eosinophil count, normal vital signs, and negative results for common infections and pneumonia. Assessment should consider alternative causes for elevated eosinophils.

**Correct Answer:**
D) Allergies

Elevated eosinophil levels often indicate allergic reactions or conditions. Given her negative test results for infections and no other significant symptoms, allergies are the most plausible cause of the irregular blood count in this scenario.

**Graphs/Diagrams Explanation:**
There are no graphs or diagrams in the provided case study.
