Question

Answer the following questions: 1. Describe the area on the slide where the RBC morphology should be perform 2. Which WBC type is usually increased in viral infections? 3. Which WBC type is usually elevated in a bacterial infection? 4. Which WBC type is usually increased in a parasitic infection? 5. Draw a slide and using arrows show the direction that should be followed when performing a differential

Answer 1

1. The area on the slide where the R. B. C morphology should be performed is the peripheral area of the slide. The blood drop should be put at one end of the slide and should be smeared using a spreader and the film should be very thin for better result.

2. Lymphocytes are the white blood cells which increases during the viral infections in the patient. If there is a viral infection, there will be increase in lymphocytes and decrease in neutrophils.

3. The type of white blood cell that usually increases in bacterial infection is neutrophils, where neutrophil increases and lymphocytes decreases.

4. Eosinophils are increased during the time of parasitic infections in the patient.

5. The slide should be made in a very thin film. The blood drop is put on the one end of the slide and taking the spreader put it over the first slide and first smear the blood in a line and the keeping the spreader in 45° angle push it down wards to the other end of the slide.
