Question 10

Complete blood count and differential is the initial laboratory test for symptomatic diverticulosis.

A complete blood count and differential is crucial for evaluating symptomatic diverticulosis as it helps identify signs of infection or inflammation, which are common in this condition.

A) Basic metabolic panel and enzymes

The basic metabolic panel measures glucose, electrolytes, and kidney function but does not specifically assess signs of diverticulosis or related complications. Therefore, it is not the appropriate initial test for this condition.

B) Coagulation panel

A coagulation panel evaluates blood clotting capabilities and is not relevant for diagnosing or evaluating diverticulosis. This test does not provide information about signs of infection or inflammation associated with diverticulosis.

C) Complete blood count and differential

The complete blood count and differential is vital in assessing for leukocytosis, which may indicate infection due to diverticulitis, a potential complication of diverticulosis. This test provides essential information that guides the clinical management of symptomatic patients.

D) Blood enzyme test

Blood enzyme tests focus on specific organ functions, such as liver or cardiac enzymes, and do not directly address the symptoms or complications associated with diverticulosis. Thus, it is not suitable as an initial test for this condition.

Conclusion

The complete blood count and differential is the most relevant initial laboratory test for symptomatic diverticulosis, as it assists in identifying potential complications like diverticulitis. The other options fail to provide pertinent information regarding the condition's diagnosis or management. Therefore, option C is the definitive correct answer.
