The granularity of each cell is measured by side scatter. Many of the cells flowing through the instrument chamber produce increased side scatter. What does this finding tell you about the cells in this patient’s sample? A. The cells have high granularity B. The cells have low granularity 2. With increased forward and side scatter, which type of cell population can be expected? A. Monocytes B. Granulocytes (neutrophils, eosinophils, basophils) C. Lymphocytes 3. The digital readout for this patient’s CBC reveals an increased population of neutrophils. Based on what you know about immunity, does this finding correlate with the patient’s possible diagnosis of meningitis? A. Yes. Increased neutrophils are an indication of active infection. B. No. Increased neutrophils do not correlate with infection.
A patient visits an urgent care center with complaints of a stiff neck and headache. While collecting the medical history, the urgent care physician assistant (PA) discovers that the patient had a lumbar tap 5 days ago. The patient’s current temperature is 101°F. The PA is concerned that the patient may have contracted meningitis. The PA orders laboratory analysis immediately, including a CBC that uses flow cytometry technology.
