Final answer:
When polys and lymphs are close together in a blood smear, it suggests an ongoing immune reaction.
Step-by-step explanation:
When polymorphonuclear leukocytes (polys) and lymphocytes (lymphs) are close together in a blood smear, you should consider the presence of an immune response. Polys, specifically neutrophils, are part of the innate immune system and are the first responders to infection or inflammation. Lymphocytes, on the other hand, are part of the adaptive immune system and are responsible for coordinating a more targeted immune response. The close proximity of these two types of leukocytes suggests an ongoing immune reaction in the body. This could be due to an infection, an autoimmune condition, or any other condition that triggers an immune response.
